This video is a live training, video that Jim Bergman did on his revolutionary measure, quick application, showing you how to use it to diagnose air conditioning systems. Here we go so this is Jim Berkman with measure quick, and we are here to do the first real live measure, quick training. We really haven't done this yet and it's pretty cool. We built this thing and I don't know that everybody has a great idea how we expected it to be used.

So I wanted to go over that a little bit tonight and just teach you guys a little bit about what measure quick does. Probably the first thing. I'm gon na go to the home screen here. My home screen looks just a hair different we're gon na do a release in the next day, or so we added some features.

You notice that the four Tenet's up in the front now I'm connected to a son of JobLink probes, so you guys can see how those work they're, probably right now, one of the best experiences with measure quicks. Just because it's streaming data, we had an opportunity to to really tie those in and do what we wanted to with them, because field piece sort opened the doors for us to do our full integration. So we're able to do a lot with the probe management really make those really shine. You know if you've been, if you haven't tried measure quick yet or where the JobLink probes you're in for a treat, because it's a really cool interface.

So what we've got here? You know our whole goal with measure quick from the get-go. Was that you you turn on the probes. You get started and you get worked. It works the way that you want to work.

You don't have to go through a certain process. You don't have to login. You don't have to do anything but turn on the app start in it and it works, and so I'm gon na start with just you know we're opening up the tool box here and I'm gon na hit the back key. Let you see you know right now: I've got this tied in with JobLink probes.

It's the only thing I have connected. Obviously, it works with the I manifold I connect and feel peace and redfish and testo, and we're integrating very quickly CPS capture hood, it's tied in with the energy conservatories, duct, testers and lowered, or some other things. Some of you guys haven't seen yet because they're parts of other programs - and we do a lot more than just what you guys see in the free version of the measure, quick application. So there's a lot more going on here than you might know about sometimes VSA.

Well, you know we haven't, hurt you guys for a while, it's because we actually have a lot of irons in the fire as we go. You know, I've got a tight end tools and, let's just start with some of the basics, so on the home screen there. We got a refrigerant, and this is really what I consider the most basic of profiles, all right. Let's talk about what a profile is.

First, a profile is an educated guess, a guess about how that piece of equipments gon na operate, we're making a judgment about how it's supposed to work, and we may or may not be right right. A profile is just a very educated guess about how the equipment supposed to operate so back in a day. Some of you guys that are older, know my age I used to say you know, AM BM plus 30 was the head pressure. We go back, I'm just going to click on this 13 to 16 seer to see that the design temperature difference or condenser tempo over ambient was ambient plus 30 degrees, and that's that's the way that that equipment worked and we'll walk up to a piece of 10 Seer, 12c, 13c or 17 C or whatever it is.

We have to make some assumptions about how that piece of equipment is how that piece of equipment is going to work, because there's not a lot of ways to skin the cat. All of the manufacturers, when they design a piece of equipment they design it pretty much the same way because they're all designing to a HRI design conditions. So when we're, when we're making assumptions about how this thing works, what we're doing is we're using typical design conditions that almost all manufacturers would use. So if you're looking at a six to nine seer piece of equipment, you know prior to the 1991, it's going to be typically 30 degrees hotter than the outdoor air, 10 to 12, seer, 25 degrees, hotter, 13 to 16, 16, 0, 20 degrees, hotter and obviously the Same thing with 17, if you get on to Lennox and Lennox always you know change things up a little bit, but you can see they have a whole different set of design temperature differences and then obviously we have custom which I'll show you in just a minute.

Here but each one of these design temperature differences, all our typical that's there of equipment and it's begun because everybody is designing to the same thing: HRI conditions or 80 degrees, return. Air 80 degree return air, wet dry wall, 50 percent, relative humidity, 95 degrees outside, and when you talk about seer rating, it's or erie ER, it's simply be to use for water power consumed. So you know the compressor is the primary load in there and, if they're gon na, if they're gon na over the amp draw the compressor, then you know typically what they do and if you watch all this hi-c recruitment, what they did is they raised the suction Pressure up and they lowered the head pressure down and you know, obviously we can use ECMs or TX vs, maybe to get a little bit more efficiency, but there's not a lot of variability there, and so so. This is an educated guess.

So I look at this when I walk up to unit the first thing I do is I say: okay, what's the refrigerant type, is it run off the nominal airflow, which typically is 400 CFM per ton? If I'm in Florida or a humid climate, you can see here, I might set up to 350 or from in the desert like an Arizona, I might set it to 450, but I said it for the climate that I'm going to work in. I set the seer which we just went into and then I set the type of metering device, thermostatic expansion valve piston, capillary, tube, the electronic expansion valve or automatic expansion valve, and each one of these settings is gon na basically give us some preliminary Diagnostics right now. We've been doing this for years and you guys have been doing profiling, even though you don't even think about really realize that when you walk up to a piece of equipment, you expect the suction line to be cool. You expect the liquid line to be warm.

If you grab a liquid line, you feel it's hot, you know there's something going on with heat rejection. If you see frost on a suction line on an air conditioner, you know that you probably have an airflow issue or you have a charge issue and that's all profiling. It's nothing! It's nothing new in there. The reason that we put these pulmonary profiles in there is so we can go right into Diagnostics and find you know what's wrong with the system and in this system here you can see I've got.

You know right now the liquid lines for the outdoor air temperature and the reason this is because we have a window air conditioner that has a slinger in it. That's throwing water up in the condenser right and then obviously we're showing low air flow, and it's because, I'm literally, on top of the evaporator, I can't get a good air flow measurement off this and there's three symptoms of low airflow on this system. So when I tap on the plus down here, I can see my supplier dry bulb. Temperature is too low.

My condenser is too low. My estimated airflow is low, my temp splits too high. These are all indicators, and you saw those changing, because this is again all happening, live and then there's some things that aren't defined like EE, R, NC R, because we haven't put in Electrical data in yet. But this is a basic profile of an air-conditioner and allows us still get some pulmonary lemon Airy idea of how the equipment's supposed to run now.

There's some there's some Easter eggs hidden in here. I just want to make sure you understand at the top here where that triangles that over the suction gage by tap on that, it's going to tell me the current value 109, what the design target this is, what measure quick is calculating, so we're measuring 109 point. 8, our design targets 114 and then there's an allowable range there. Okay, it should be between 107 and 120 and that's all based upon allowable saturation temperatures in there.

So we talked you know it's a plus or minus 5 degrees of superheat. So we look at 5 degrees of saturation, that's a allowable range in there and that's and we pick a target based upon design temperature differences. And then you know, touch indicators on brandish, got touch up longer here. It's all based upon designed temperature differences, and then it shows you if that measurement is in or out of range same thing here.

If we tap on the high side, gage I'll, try and tap it long enough that we can see it here, it's telling us that this is below the allowable range. What the current value is the design target is, and then the allowable range of bed pressure on here and then obviously down on the information screen down here, where the eye is it's telling us that you know what what what we're looking for there. So if the, if the condenser pressure is low and saturation temperature is low, then it doesn't occur as a singular problem, but it could be the result of a wet condenser at which we have write a low refrigerant charge, low load, all those things. So eventually, we should probably put a profile in here for window air conditioners, but we don't have one end because nobody uses it now.

If we, if we take a look also here at the we can scroll through, we can see our suction line. Temp superheat sub cooled liquid light. Now again, all these are our targets that that measure quick is calculating, and this is a big upgrade from what we did in the I manifold system, because I manifold gave you suction line temperature, but it didn't tell you what the current value is, what the calculator Target was and what the ideal range is. This is one of the ways that we significantly significantly expanded the troubleshooting ability of the measure application.

It can do things now. We just couldn't do in the I manifold app same thing with super heat. If you tap on any one of those - and in some of these things like if there's details on there, like I'm super heat, Brian happened to write an article about HVAC school about super heat on there and we tied those things in so you can go and Read that article we call it Just In Time education there. So we know, what's our my super heat B and it goes through and walks you through that article in there and we're tying in as Brian's writing more and more articles we're tying those in.

So we can help you guys out is if you get lost on what something should be, so we got sub cooling, wet liquid line sort of the same thing. Everything, though, has a target on there. I'm gon na slip the slip, the sweet screen again. You can see our outdoor temperature and some things you wouldn't think would have a target like out the where well we tap on outdoor, where it does have a definitive target, because, typically, when you look at design of an air conditioning system, it's designed to operate between 170 and 115 right and if we're outside of those conditions, it's really not ideal for the air conditioner operate, you may find it on some manufacturers extended extended tables, but if it's 70 degrees outdoors and 70 degrees in the house, it's you know or even though, there's Really not a lot of we typically don't run air conditioning except for commercial applications.

When it's you know when, in the outdoor temperatures to equal the indoor temperature, we may have some some other loads in the house. We're required to run it, but what I'm getting at is there are allowable ranges for that, and there are ambient conditions that that are drivers in there, and so, when we get too cold out there, it's again just flag in that it's not it's less than ideal To check the equipment now approach, you can see that we have a negative approach here, and I've told you guys the answer to this two times already. What is approach approaches? How close is the liquid line temperature to the outdoor air temperature, in fact that liquid line temperature should always be a bit warmer than the outdoor air temperature? But in this case here, because we have that water, it's a window units swing them into the into the condenser and we're evaporating. We have a evaporative type condenser on there and what that's doing is it is boiling water off the off the condenser, coil and cooling.

The liquid down below the shop temperature here right, so that's why we have that negative approach on there. Typically, that would be in the green on a regular system on this window. Air conditioner, obviously we're not compression ratio is just a again if you, if you didn't know what that was, there's article here on the HVC school work, we're talking with the current value is, and the ideal value is and a measure quicker. We can calculate the exact compression ratio because I'm calculating exactly what the suction pressure should be and exactly what the liquid pressure should be.

So those are targets based upon the load condition. This isn't based upon HRI conditions. This is on to the conditions you're running on discharge line temperature, a lot of guys, don't measure it. It's actually, in my mind, probably one of the most important measurements, because we always want to make sure that discharge line is below 225, because high discharge line temperature is linked to oil failure.

And we want to make sure that we don't break down the oil and ruin the compressor I'll slide again here and you see we got returner, wet balls and drywall supplier, wet balls and dry bolts slide again here and you can see our change in enthalpy air Flow temperature split all these different readings on here now again, what's really interesting here, when you think about the Diagnostics know, we know it's showing a low airflow there we can see, we have low standard CFM. We have a high change in enthalpy. A high change. Numpy is indicative of a of a low airflow.

We have a high temp sweat, which is indicative of a low airflow right I'll slide back here. Just a little bit, we have a low supplier, drywall temperature, which is indicative of low air flow. So all these things when look at these might app on us again, you can see there's four symptoms and low airflow and that's what those are. If we get up to five symptoms of low airflow, then the will not allow you to clear it out on the Diagnostics, but we made it so you could clear it out so that if you, if you've, checked something like a system condenser, maybe dirty.

If you want to clear that toute, you can clear it out if, if you know you've measured the airflow over the Captur hood, you know it's not low airflow. You just have bad probe position. You could clear that out and that will be used for Diagnostics reports in the future slide across again we have our BTUs total, sensible, late and sensible heat ratio and then slide across again, and you can see we have a er now this just all with the Blanks, because we have nothing here and I'm going to go ahead and put in a couple of other electrical readings, 1:21 and we'll do Oh point seven, because I've measured these before and you can see it the first time I got those readings. They came from the redfish meter, that's what the little redfish meter is in the corner and I'm just going to go ahead and submit here now and now you can see we have our EE.

Are we ever seer running on our piece of equipment? Now what we didn't talk about here is on the bottom here I'll walk through that in just a minute, but all the data in here pretty much streaming off probes. We can also manually input data I'll make sure you guys know where that's done, we'll slide. One more screen here we have weather data. This is current outdoor air temperature, relative humidity, atmospheric pressure elevation.

We use this for some corrections for air density and calculations like if you're in Colorado or something we know you're at a high altitude. We might make some suggestions for air flow and things like that in the in any application. Now, if I go back the to the let's go to the outdoor, so there's these buttons across the bottom are information basic senses of information. The sunshine is your outdoor readings.

Everything you'd measure outdoor the home is everything in measure indoor, the lightning bolt is all your performance and your electrical and then the obviously the weather icon there. If I tap on outdoor measurements, what that does is it brings up all the data you can see. All this data is streaming in live from JobLink probes. If I were to turn off the outdoor air temperature probe, that would actually go to user input box, like we saw a few seconds ago on that on that job, leg screen or I'll sue me on that electrical screen and each will these things it's really cool.

We measure quick is, we know every single tool, that's being used in your in your application, what it's being used to measure so for some of our utility clients and things like that that that's really important because they want to. You know we want to know well the quality of tools that are being used to make the measurements, if they're approved, for the program that they're doing in California. There's approve tool lists, and things like that. So we need to make sure that we know what all the measurements came from if their user input measurements things like that, so we can give what's called a confidence score for the for the tests, because we know if everything came off probes and everything that came Off high quality probes that the odds are, although all the data is really really good, because there's no transcriptional errors, there's no fat fingering! There's nothing like that.

That's going to screw up that up that data indoors here will tap on the indoor measurements. You can see that we have a return, air and supplier, but now you'll see down here that we have a calculator. So that's a calculated value because the probes, the field piece probes, they read, returned air temperature and every return air relative humidity and then from those values we're calculating the return. Air, wet, bulb, temperature right same thing with supply.

We get temperature and humidity and we're calculating the supplier wet ball and then from that we're measuring our estimated CFM. That's a calculated value if we had a measured, CFM and I'll show you this here. Let me just go here: I'm just going to toolbox, I'm gon na turn on the test: Oh 420, which is a capture, hood and I'll, go back to the home screen and go back to the indoor measurements. If I, if I wanted to measure that with a test of capture hood, I could just hit the measure key and if I had to, could activate it and we'll pull that hold that out.

If I have multiple grills like in California, you know they have a lot of Central returns and I want to add a grill in there. I get to sit at a grill and it would add another grill and I can make a second measurement and then it'll add those together and give us the total air flow on there, and I can add, multiple grills on there remove the grill. If I want to remove it total external static pressure, we do not yet support the I manifold manometer, eventually we'll have that supported there's. Also, if you look here, you can't see where my fingers tapping, but at the top of my keyboard there are up and down arrows and sometimes that makes it a whole heck wat easier to navigate through fields in the application.

So you can, you can tap on those and those will go up and down fields. You can see it's going from the 2 to the 3 as I'm capping that and we use those a lot in the in akin to go to the next field. On there and now when I hit submit - and I go to that indoor - go to my performance readings here, I'll tap - that again, you can see it's a got: a half an inch total external static pressure. So there's multiple ways to move to the app two.

I can either do it. You can see my hand here, I'm doing a swipe right, so I can swipe back and forth and make those move or I can just tap on the outdoor and you can see when there's two little dots oops it's touchy because I'm touching certain spots here, but There's two little dots down there. That means there's two screens. So when I tap that outdoor again it goes the second screen indoor first screen indoor second screen, then we go to like outdoor air temperature.

Weather conditions is only one if I tap on the weather conditions. It's telling me, you know: here's the pressures, elevation, temperatures etc and again for a utility clients when they have like very specific requirements that you're above seventy, when you're checking the air conditioner of things like that. This is how we confirm that that's done, and that goes in by a geolocation on there. So the next question we always get is okay.

Well, Hajin tend to use this because this is just like a basic overview. So these are all the things you can do without ever really starting a project on here now. Let me show you how I intended this thing to actually be used and by the way we did add this for 10a at the refrigerant at the top. If you tap that now, you can just change your refrigerant.

You notice that around the gauges here, this gauge band changes color. So that's green, indicating the refrigerant it just wasn't quite enough for me when I was working and I take this out and use it. You know on some systems, actually go in the field and do testing it. Just wasn't quite enough, so I had Bobby add that at the top, so you can have a quick access and that's cool as you can access it from any screen on unmeasured, quick.

It makes it really easy to use so, let's take you through and let me show you how we do a project on this thing and and how the project works. So you can see we have a system test, a non-evasive test, Energy, Star checklist. We have some stuff that's coming soon, if you're in utility programs things like that, there's a lot more stuff. You might see on this there's projects that are hidden because not everybody has the same accesses in here.

So we're gon na go through a general system test. It's going to ask you if you want to create a new project now. One thing I want to drive home here, because Bobby's put a ton of time and putting pop-ups in here that are always very, very relevant. Read the pop ups follow the directions, because, if it tells you to do something before you hit continue sometimes like with electrical it's moving, you it's saying you know, remove your your meter reads, put in your clamp and then hit continue, because it's looking for the clamp In there - and if you don't do it in that order, it's going to give you.

You know some challenges. You have to go back and redo it again, but these pop ups are here so that it makes the app work better. Not just be an annoyance, and I don't know how many times people have just closed a pop-up before they even read it. Then they call for tech, support and - and you know, we're walking them through all those things now.

The second thing is, I want to drive home. Is we have just to over 20,000 downloads of our application out there? You guys all know that none of you have paid a dime to use this application and we wanted to keep a lot of this at no charge here and it'll remain that way. Things like putting your tools in your toolbox and stuff like that, but it's tough when you get that many customers out there and we're trying to really support the product, and you guys know we pick up the phone and answer questions we're trying to put the stuff In to help you guys make sure you're taking advantage of it so that we don't so we eliminate phone calls and any guys get the most out. So there's a whole.

Let me back up just one step here. One really cool thing is: is we're coming out with a with a desktop application for this and I'll talk a little bit in a little while about how we are going to fund this cuz? Eventually, you know we do have multiple revenue streams. We have some big clients that are using this stuff and they're using it for very specific projects, and that helps subsidize what we give away for free - and you know I'm a big buff on education, and so one of the things that we're trying to do is Not charge anybody anything unless we're increasing your productivity and that that means beyond what you guys see here tonight. That means like pre-population of job sites and pre-population of equipment.

Things like that we'll get in that later, but our desktop application will actually allow you to have somebody at the office. Pre populate all of the data here on measure, quick, so that when you come out in the field literally, all you do is go to your measurements screen and save the data. You know look up your probes set them out. There review everything and save the data.

So what I'm going to show you here, you may not have to do in the future, because once you've been out to a job once that data is stored, you shouldn't have to come back out there again and I'll show you that when we get to the End here so notes will be something your your office could put notes in there. You could put notes in there. You know about the job site. It's just a place to add notes that I'll end up on the report there, I'm just going to put tests there.

Now, job site, this is physically marking the location of the site where and I'm in the corner of the building. Here it doesn't know I'm not in this building. Gps is not hyper precision when you're in a building like this, because I'm tied to Wi-Fi when you get it when you get on a jobsite, it might be a lot more accurate or it might be less accurate. It all depends on where you're at so what you want to do on this is drag and drop the pin over and Mark the building.

The first time we're doing this. We're marking the building on here you'll see it automatically generated a site name, I'm going to click on the customer information, and this is where I'll enter in my information, and you can see it automatically populated my address for me, my city, my state, my zip code, Where I'm at here at the office I had submit - and now I hit submit here and you can see that went green now. This next step is probably the most important step when we're doing a system here, and so what I want to do next, I'm going to drag the pin over drop it on the building, but then I'm going to zoom in on the map. What I want to do here is mark physically mark the piece of equipment I'm working on, so I'm going to mark that rooftop yet there.

If I couldn't mark the piece of equipment because maybe wasn't a bush, I might just mark the general location of the equipment. What I'm trying to do here mark the equipment location, so somebody knows what piece of equipment was serviced and when I, when I pull this up later, I know that each piece it was serviced the date and time it was serviced. And when I pull up my map, when I, when I arrive at the job site, it'll, show me what a piece of equipment needs service, I'll click on that pin and I'll just start start the job and I'll show you how that works in just a minute. Here so system information we're just going to make this a package just to make it easy.

You can see that we're doing splits mini splits package units. This is going to open up by the way very quickly into gas heating, and things like that. We're going to go ahead and put in a make so we'll just say a window unit: they notice that automatically it it. It capitalizes those things as we go to the next field.

If I wanted to take a photo of anything, just click on the photo I'll. Just take a photo of a television here and I had use that photo and then that photo will come up in a report later and I hit submit and that's in there installation information now there's a lot of good information here you want to collect. You know it's a rooftop unit on the ground is its own system. What's the filter type is a pleated throwaway, the filter manufacturer.

If we know that we can add that in there put it in our filter size, so we'll just say it's a sixteen by twenty by one and then if we have to add in there or remove, we can do that at a return. Grill we'll hit submit. So now our profile now you'll notice that in the profile here there's a lot of different settings. So this is again it's a package instance.

I would say it's a three-quarter ton. That's what it is. It's a little window. Air conditioner well keep that 13 to 16 and we'll mark.

This is a capillary tube, because that's what the metering device is on there you'll notice that the super heats auto calculated on there all right. Whenever you have all the probes that are like JobLink probes and things like that, we can calculate those targets, superheat should be. We can put in our total external static pressure. This is we get off the label of the air hand where the furnace, this is, are available, static and I'll.

Put that in there and hit submit now before you'd submit here, I'm going to open up the extended performance if you're. If you know what the extended performance is like, you've run a heat loss calculation and you know you're not using HR design you're using custom extended whatever that is. You can put all that data in here and instead of using nominal tonnage. -- is to estimate where your your capacity should be based on your load conditions that will actually use more detailed information.

You don't know it's no big deal just close that up and hit submit. So now we get into electrical information, and all this is asking us. You know it's a single-phase unit, a nominal voltage, 115 evaporator phase single phase nominal voltage, 115 evaporator fan type in this case is the PSC. The reason we have different kinds of motors PSC, ECM x13 is because they have different power factors and so we're doing electrical readings in there.

If you don't know the power factor we're using an assumed power factor, if you do know it like you're, using a watt meter test a watt meter or very soon here, the red fish meter, you can it'll pull in the power factor, the actual power factor. That's there so now I'm going to hit submit so now all that data is in and we're to the point now or we're going to take measurements on the system you you may or may not have started the system before this point. You're right I mean it takes typically for a cap tube system. It takes about seven to eight minutes to actually get stabilized there.

On these view, you can view any of the measurements you want to view right and what we're doing here, the way what I use this for typically is just going through and making sure all the readings are populated, and I don't have anything I left out making Sure I got volts and amps everywhere, making sure that everything that I want in is in this is where I can review my performance calculations. I can see the system was stable. I can see my now. You can see here it's nominal titer, just three quarters of a ton so 0.75 times 12, thousands, nine thousand, but now it's normalized.

Now normalization is based upon several factors. It's based upon the outdoor air temperature right. It's based upon the return, air, wet, bulb and dry bulb. It's based upon the airflow that the machine has is based upon.

The liquid line. Length is based upon the voltage, there's several things here that actually impact the performance and when we normalize the system, what we're doing is normalizing for current load conditions. So you can see right here that we're doing eight thousand three hundred thirty-nine BTUs and it's going between. Ninety nine ninety seven hundred one percent of normal capacity, because the window air conditioner, is doing everything it's supposed to do so.

You're not chasing you're, not losing a thousand BTUs. It's under these load conditions. It's supposed to be doing about eight thousand BTUs of cooling and the reason it's a little touchy like this is that the field piece probes are extremely sensitive and I'm in a window. Air conditioner very, very close to the outlet and it's the air is a little turbulent in there.

Otherwise it'd be a little bit more stable. We can see our sensible is doing 86 % of our normalized capacity and our Layton's doing one hundred fifty-three percent. Now again, it's got low low. It looks like low air flow right here right now and that low air flow is gon na kick up our latent capacity and it's going to rob of sensible capacity.

So it's it's when we're looking at the total capacity. It's fine, but here's the thing you got to look at right here if we're only doing 86 % of our sensible capacity right, 140 percent of our latent capacity. What that means is is that our system, even though it's running at full capacity, it's going to run forever to try and satisfy the thermostat, because the only thing that satisfies the thermostat is sensible, heat right, the thermostat just measures temperature, it's not a comfort stat. It doesn't know when you're comfortable, it knows when the temperatures achieved and the sensible heat is.

What actually does that for us. So when we're running eighty six percent of our sons way of low air flow, if we were to adjust that up and get the air flow correct, then what we would see is we'd see a shift which your latent capacity go down or sensible capacity go up. Our total capacity would stay about the same, but now our system is gon na operate much much more efficiently because it's going to cycle off during the peak demand periods. So when you guys go out there and you see low air flow - and you know a lot of guys look at actual capacity, a total capacity go.

Ninety nine point: nine whew! That's great! No! It's not it's not great, because yeah you're getting full capacity out of the machine, but it's a wrong kind capacity right. So you want to make sure that you pay close attention to that sensible capacity, because that's always what your real target is. Sensible heat ratio just means we're doing 67 % sensible cooling right. If you look at that ratio, it's five five hundred and five thousand seven hundred BTUs, two thousand seven hundred, so that's a ratio of 68 % and typically we want to see that around point.

Seven. Four point: seven: five you get into like Brian's climate zone. This might be a little more normal, actually, where you see a higher latent capacity, typically even a toe in humid climates. We run about a point.

Seven, I say you're going to see that run from point. Seven two about point: seven: six is the typical range you'll see sensible heat ratio when everything's running normal, but if you've got a really really hot humid pull down, it's it may shift over to almost you know, to even a 50 % latent capacity until it gets In the into the load there now you also notice that we have air flow nominal. This is a 300 CFM per ton. Again, it's it's 0.75 times 400 right, so 75 % of 400 is 300.

Our estimated airflow is 191 you'll, see that there's two different types of air flow there. They are standard, CFM and actual CFM, and what these are are mass flows. So a standard CFM is point: zero, seven, five pounds per cubic foot so point zero, seven. Five times 400 is 30 pounds per minute per ton now because our air density, if you scroll down to the bottom here, you'll see our air density return.

Air density is point zero. Seven, two! It's not point zero, seven, five point: zero, seven, five standard air we're actually below that, so it requires more actual CFM, 206 actual CFM. To give us the 193 standard CFM that we're measuring across the coil right so depending on the type of measurement device you're using some, some of them measures standard CFM, some as your actual CFM some measure up in between. But this is what all of your air conditioning equations are based upon standard air.

So when we're talking about you need 400s CFM or 350s CFM, that's what you need across the quill list number you want to be paying close attention to now. We also have our temperature split, in this case, your tempter splits 27.1 and our target temperature, splits, 19 and a half so the target. You know it's got the little target right here next to it, and that's that showing us that that's what our split should be and then our actual is above the humidification we're pulling out 2.4 pounds per hour and it's about 0.3 gallons per hour. And then our eer sear and fan of efficacy.

Now all these ratings here are based upon that tonnage. You put in right if I turn this unit to a 2-ton. If I go into the information - and I tell my my system instead of being a 3/4 ton - that it's a 3 ton and I hit submit when I go back to this performance now - you can see we went to 32,000 BTUs and we're doing 3 tons of Cooling and it's still 97 %, and but now it thinks it's a 3 ton system measure quick can tell you how many pounds of air per ton you're moving across the coil or the or the CFM per ton. But it can't tell you the tonnage, so it just multiplies it.

So, instead of being, if we went to one ton of air, then we're multiplying it times, 3 wort 3 tons. That's all it's doing there. So it's very important that you put in the that you put in the right tonnage of the unit, otherwise you're going to get something: that's not reflective of what you're, what you're doing there by default. It goes so everything goes to 1 ton when you open up the app out there.

Let's go back to the performance for just a minute, we'll make sure we covered everything in there and we talked about dehumidification. We haven't quite done it. Yet we're going to have also returned air face velocity and that's just going to take the area of your filter and it's going to calculate your face. Velocity across your filter and typically you want at base velocities of about 200 feet per minute across your filter.

For it to effectively filter and different filters have different base, velocities that are that are acceptable, but if your face velocity gets too high, if you have too small of a filter, what's going to happen, is you're going to end up with a basically pulling the dirt Right through go back here, let me change one thing, because I see that I didn't change that to a I did. Okay, I got to change it in the project. We go back here. Sometimes I just noticed this on here and I'm going to go back again here I changed it there.

There are multiple places, things could be changed and because I changed that there I need to probably change it here. Let me see if that fixes that sometimes doing a project it can. You can make things you can screw stuff up, and I hope I didn't do that here, but I'll just make sure okay everything's back into place. I just had to update that the project, because when I changed on the home screen it didn't update in the project once you're a project.

You really should work in the project and not outside of it, but will actually fix that. So all the data ports back across there, alright so performance. Here we got all that kind of stuff. You can see our actual EE R 10.8 one enter approximate C R, there's a formula that you can convert EE R to see R and that's what we're doing so.

It's an approximate see rating of that piece of equipment fan. Efficacy is just simply the CFM per watt of power consumed. They use this in California. A lot then make sure your fans running efficiently.

We go back to the performance saying and I slide a screen here. You can see the fan Africa see in this case is 0.41 by tap on that typical allowable range is 0.12 0.58, so we want to see at least our under 0.58 watts per CFM of power used on there. That's pretty typical and again. This is why we put all the targets in here, so you guys can you can see how things are running and see, see what's going on here and make sure things are all in the target range, so go back to performance for a minute here and we'll Scroll back down, we've also got here, are our bypass factor.

This is how much air is going through the coil and condition we've got to return our enthalpy or supply or enthalpy. Our change in enthalpy enthalpy is just B to user pounds. So it's how much how many BTUs are in each pound of air how many were removed? I returned our dew point supply our dew point. These are really important because a coil needs to be below the dew point temperature to remove humidity and then a return.

Air density and supplier density and these are used for calculations about air flow and things like that in the application, that's all of our performance. So, let's go back in this project here I'll hit submit now, I'm gon na go take my measurements, and literally all I have to do at this point is: I can check my Diagnostics, see if there's any Diagnostics, so you know I know, there's no restriction here And actually I'm over charged on this and I actually do have low airflow and it's because I've filled out a complete profile on here. So these are our two things that are wrong with that system and eventually, we'll have a fault report there and again. This is all of the minor faults we're not quite yet tied in to the HRI database I'll show.

So let me just asked about that so maybe to show you here in the equipment, information in the models and serial numbers once we get our cloud up and running which be in the next few weeks here, you'll be able to put in an H or a Reference number and it'll pull in all the model numbers for you on that package. You know all you have to do is put in the serial numbers. It does also have barcode scanning and that's what that is on the on the right there. The far rate, if I tap on that, if I tap on that barcode and what I'm going to do, is I'm just going to bring a barcode into the end of the screen there? Okay, to pick it up the QR code, let me scan it one more time here cover the QR code, with my thumb there pulled in the barcode that time so now you can see that pulled in the model number or serial number effectively.

Now, a lot of equipment - this is really hid. Miss some has QR codes, some has barcodes. Sometimes you have to go in and edit these things. You know - and you know edit on Apple just by pressing and holding it, and you go in there and you can edit the number you might have to wipe out half of it or something because, like Lennox, brings in a model and serial number in the same Barcode, so you do it once you wipe out the model.

Second time you wipe out the serial. If it works great, if it doesn't work, you got to enter it by hand. We can't control what the manufacturers put in their barcodes it just the way. It is.

It's not us, it's not that we can't read the barcode, it's that the manufacturers aren't always putting models and serial numbers in their barcodes. So we've seen some some of the guys. I think Lennox equipment does a very good job of it and other guys tell me you know it doesn't work, but it's because they're, you know maybe they're a pain dealer or something and for whatever reason they just don't do the bar coats the same, but it Is a little bit hit miss on there? So now I'm going to hit submit and I got my measurements and I'm just gon na hit. You know save data at this point and when I hit save data now all those measurements are in the project and I'm going to hit exit project here and it's saying that the project will be deactivated and it can't be reactivated from there.

It can be reactivated from results to have Ken something it. Okay and I'm gon na go to results now so now in the results. Tab and show me that my my AC system results and I'm gon na just hit hit the test results and I'm gon na. I can view my Diagnostics if there were any so in this case I had you know when I, when I did this test, I had low air flow.

I had liquid line temperature below ambient temperature. I can see uh, neither any of the stuff I had. I can see all my performance calculations. I can see in my environmental conditions that were in there and I can hit share at the bottom and export as a PDF and it'll pull up that report.

Now, if you notice, when we're right there, I marked the piece of equipment before I started with the exact location. So it's marking that piece of equipment on the roof that I did the job with notice that it's telling me it's a package unit. You know nominal tonnage here, refrigerant metering device, all that kind of stuff the system was stable. You can see what came off Jobling probes.

What was calculated. You can see that I had data enter by hand because there's nothing next to it on there and I can see compressor amperage those voltages all my capacities, my high sensible, my low weight and capacity all that stuff's in a report, and when I'm done with that Report - I just hit done, and let me do this again here - export PDF up at the top here. I can save that to Dropbox. I can mail it.

I can add it to notes. I could save it to my file and print that whatever I want to do that with that report on. Let me go to the home screen here and we're not in a project right now. So once the project submit wipes out some of the data and somebody's asking about superheat and what we're looking at for superheat right now, this is total superheat and almost every residential application.

We do do total superheat calculation, it's not evaporator superheated. We will have set up eventually in the tool box here the ability to map these probes out. So you can see here at the top. I have a you know: low pressure, high pressure, suction line town.

Eventually, we will have that we can have that suction line. Time of the condenser or suction line top of the evaporator we're going to be looking at both because I think we can run about 24 25 probes on this top link stuff right now. So it's very, very cool, we'll be able to see all the data and you can see we even though fuel piece doesn't have an outdoor air temperature, we're able to remap that hydrometer. You can obviously map this to return air map, the style thoria.

Now, there's some basic mapping in here and all you do is just tap on the tap on the probe, but you can do some basic mapping, but this allows it to come in. You also notice that they're going green, yellow orange green and what this does is. It's telling us each time new data comes in and how many seconds have elapsed on there if it goes longer than 3 seconds it changes color and then, if it's 5 seconds it goes the next color you can see these come in very consistently. So that return here when they're going yellow like that means it's been three seconds because it's got a reading, it goes to orange.

You might see one go to orange there. It might be five seconds. I think five seconds is red. I have to ask Bobby.

We might put it at the bottom there, but basically, what we did is we just watching the probes to making sure they're all coming in and coming out and then looking at the network traffic, yes more or less on there and we hold those readings in on There so they don't go to blanks, but they're only held in for refused in some cases for a few seconds in some cases, for a few minutes, so things like return, air and supplier, they don't change very quickly. I mean the house temperature just doesn't change dramatically. It's not going to change and you know, buy it like two or three degrees in in 10 minutes and what we decided to do here is to hold those readings in, but to tell you when those readings are going away, and we do that I'll show you In just a second, where we do that at we do it on this screen. Obviously, but we also do it on the home screen in the center and if I tap on this, it's going to go to the, but in the center right there right.

It's kind of when I tapped it goes in the menu, but in the center, where the needle is that'll actually go to red. If the probe loses can action to indicate from the home screen, you lost connection on there. You know it's, because these are Bluetooth. You get into a big job where you can't, in fact, if you watch their closely, you just saw whet Bob red for just a second.

For some reason, you don't get a reading in right away. What we do is we hold it so that, like let's say, you're on a big job and it's just the range just won't quite make it. You can walk into range, get a set a return, air and supplier readings, walk back to the condenser and it'll still run. All the Diagnostics is going to work off those readings for 10 minutes suction pressure and liquid line temperature.

I think it's only got a like. 30 seconds, because those change relatively quickly - and we don't want to hold those for a long period of time - and this goes - the guns goes back into our utility clients for our measurement confidence. We want to make sure that we have very consistent readings in there and that the readings aren't you know they are, they aren't going read. It hasn't been too long in there, even though it goes to read.

It just means it hasn't gotten a reading and, let's say three seconds or something like that, we may adjust the frequency on those timings we're playing with it still to see what's ideal. But the whole concept here is to let you know from the home screen that you lost connection to a probe and that, if you're going to you know it's like, if we're charging a fixed, orifice metering device or something that then it's been longer than 10 minutes, You need to go back and get another set of readings, so you don't over charge your under charge your unit inadvertently on there now a couple other things here. I want to go Trillian results, so one thing: if we go back to the results tab here, we can also view these on a map. So when I hit map what it does, it looks at the job I'm at and if i zoom in here, I can now pull up that project.

The one we just did and I can view it or I can set it as active or whatever I want to do so. I said this is active if I've been out to this job site once I said this is active now when I go to my home screen and I go into my project here notice, all the data is already in there. I can go into measurements tab and I can you know, redo those measurements. It saved data again and pull on a new set of measurements into that system.

There - and I just don't see it on here right now, when probably update this. There was a clear measurements button and I might be just missing it here, but we had at the top earlier clear it's button where you could clear out those measurements and then take a new set and we'll have to add that back in. But the whole concept here is at a local level if you've been out this job before you don't have to re-enter that data, and this right now would take if I save the data, it's taking a whole new set of data for that job. But if I go back here, you know just exit the project here, we'll go hit.

Okay, if I go back to results, you'll see, there's three test results, three different date and time stamps. So that's all new data that came in to that report and it's state and time-stamped when it's in so the concept here is you know you don't have to do that? The beauty of this is unless we go to a cloud-based stuff. Is everybody? That's at your company will have access to those projects, and this is where we get into a paid service. It might cost you a quarter to pull that data down and into your application right.

We're gon na. Have this set up with a we call them qubits, which are just credits, so you can buy a block of you, know ten bucks and you could get 40 cubits and basically, when you go out to a job site now, anybody in your company, this can be. Are used by company-wide right, it's like buying a big box of wire nuts. Everybody in the office goes and gets a few, but this is all managed electronically and when you go out and download that you know you pay a quarter and that's one of the ways we were financing measure quick now you don't have to do that.

If you want to store them locally, you know your one-man shop, that you could use this for free and and it's sitting there on your application, but cloud store just gon na allow you to you know to never lose those records like your device, gets stolen or Lost or whatever they're permanently stored up there and that's the beauty of the cloud site stuff. The concept here is you know for what you have to enter model number serial numbers equipment, information lines that length all that kind of stuff takes about 15 minutes. If you're, you know 10 minutes or so, if you're shops charge - and let's say you know all in that your cost to companies $ 60, an hour which is not unreasonable.
