 We've got us a what I think is gonna be pretty typical package unit here. Let's go take a look I've never liked this unit because I think it's a snap together kind of a chintzy thing made out of plastic everything strips out Screws don't work very well, and you can't really check the charge without propping this door on this video is brought to you in part by TrueTech tools quality tools essential support What's going on guys, so we're gonna get started here on this job Got a new toy got two new toys Got thermal imager here. We're gonna be doing a Few calls with here. Maybe we'll check it out here today. It's supposed to be pretty it's been pretty cool so far Now finally got me a posi lock This thing here is for pulling those hubs that I can't get sometimes this thing is wicked Looking forward to using this thing. They are expensive, but they're made in America So it gives you two different monster hubs here, and you can see how big that sucker is And then the locking mechanism goes down onto this cage deal here So yeah, Madden mark assembled in America. Anyhow, this here tightens up the cage and you can pull it So anyhow, we've got us a what I think is going to be pretty typical package unit here. Let's go take a look it's Had a tendency to freeze up and It's got a little bit of history It's always a really good sign when you walk up on it and it has our 22 bottle laying there Which has refrigerant in it. So what we've got going on here is dirty hasn't been cleaned out from what I can gather I mean it you can see some light through the coil back here, but he had it freeze up and then Turned it off and then turned it back on so it could freeze up again Missing a trap there. So we're draining out on different areas Disconnect box left open. So let's get it open see what we got Got here's we get what it keeps freezing up that don't look good and Feels like it's fine if not overcharged So why is it freezing up? Let's get a look at that evaporator. See if it's dirty go ahead and took the side off here Vaporator don't look too horrible. I'm gonna morsh it out. I don't get too worried about it when When it's outside here just drains on the ground and through the bottom of it I'm gonna need to put this cover on it's kind of a bad design if you just try to wash it out with that Oh, if you're gonna get it all in that control board the Burners and stuff there need cleaned out and blown out may blow that out here in a little bit That should make it a little easier to get in there to that we's able to run the Gird knows up to that window Now that could look clean and but not be clean so we may have to yank The blower or we'll see if we can get through it With the hose there Most of it's all coming out through the drain If we got good suction pressure, we'll know that we Aren't restricted too badly Mainly comes down just basic magnets as usual I think it's gonna be an airflow issue The return air is on this side of the building which is one little business and he's got the thermostat is on the other side And this guy on this side here with most supply registers has no return air So it's not the greatest design thermostat like I said Can be it turned down kind of low at night and freeze up so it's kind of a Little bit of a mess the way it is. Okay, we got that done. No water got into the board, which is good that back washed out through here Make sure there's no Crap cotton middle of the coil. I never know We'll look at the other side and see if a bunch of black crap come out if it did And we know we need to pull that blower and get in there really big time Yeah, I do not see anything on this side of the coil. So I'd say we're probably good there Let's go ahead and get this thing back together and check refrigerant charge a feeling that we're probably not going to find anything because the mixture between airflow issue and Riding it too cold. This is gonna be done by super heat because there's no TXV So we've got everything probed up I've never liked this unit because I think it's a snap together kind of a chintzy thing made out of plastic Everything strips out screws don't work very well And you can't really check the charge without propping this door on so we're gonna try to get that on there Usually just run a screw into that cross member. They're going vertical That'll hold the door on good enough for while we're doing our tests keeps the return air pulling through the evaporator So right now we're running a 36 degree of an operator. It just came on so obviously we can't get too crazy Super heat's already eight and diving. It's probably overcharged beans are simple needs 28 degrees 97 degree liquid temperature hot door temperature. I'm gonna guesstimate probably seven areas. So about to check that. Yep Chances are this was charged by the handbrake method or beer can cold in other words Yep to two degrees there What it was they probably did that to push the suction temperature up saturated suction temperature to above freezing Would not surprise me, but it's overcharged Now we're up to 30 and don't forget where condenser coil is still wet. That's it's gonna change even more as it runs Also, it's a so-called commercial application, but no fan cycle switch on it either We're gonna go ahead and check our super heat here. So I've got the probes on Drilled a hole now. I've got a poke a hole through the insulation Because they did insulate it. Oh They got two boxes there. That's really convenient for the service guy in it So they just got a fake box on the outside. Let's go ahead and drill a hole through the door I'll tell you this much if you're gonna complain about me drilling a hole through that It's a whole lot worse on that compressor being flooded back like it's doing right now. We got a 41.9 degree evaporator versus a 41.5 Saturated temperature. We're actually coming back liquid That's a whole lot worse. I'm putting a stupid hole in the door So before you leave a comment about it I'll put a piece of tape or a piece of silicone whatever not a big deal. So let's go ahead and get us a supply temp also which Probably pretty sure we can go on this side of the door here We could go inside might be able to actually yeah, I'm not sure how this is kind of a Interesting design here There we go. Yep So they got insulated duct trunk there And they just wrap this around it to hide it maybe a flex duck even I don't know Supply must go right into the inside. So we got our probe set up Get the return there. We got our outdoor temperature here since we're doing super heat on this particular one We're actually using the 605 eyes Sometimes depending on what it is you're doing if you're doing temperature rise you'll have to use the 915 Which is capable of doing just regular old temperature only. So what we did is we came into our settings And we picked smart probe or manual inputs. You can do either or so it's 77 degrees according to that right there Which within a degree or two what it actually was they returned coming in 62 which is kind of surprising So what we did is we told the gauges that I wanted to do super heat super heat target is 14 degrees We literally can have this thing charge itself if it was low I can put my wireless Silinoid on there and actually charge it. So what we're going to do is recover some of this into a tank and Like right now it shows right here That we have point one super heat, but we do know that we need a 14 degree super heat So we can escape back out of here. That was charging by super heat. We got charging by sub cooling Then you got recovery So back to regular old refrigerant charge We know that we are overcharged sub cooling. There's 26 which we can write down. So we remember And we had pretty much zero on super heat So let's go ahead and get this blown into a container and see what we're coming at We're getting closer there outdoor temperature here like I was saying earlier now is Outdoor dry bulb temperature 76.6. I've got 75. So we're within a degree degree and a half our return bulb temperature 62 wet bulb and Calculated super heat is 15 degrees now We can see our pressures over here is this kind of a clone of the gauge and you can see your sub cooling super heat everything's on the App here, but it clones it So you got to do your changes here and it shows up over here and you do get more More to see with the phone app target is 15. We're at 13. So we're right in there This is very sensitive. I took up just a little bit out how to add just a touch more in I'm talking probably not even Six ounces eight ounces. It's very minuscule So it's it was easy for whoever to overcharge it Yeah, this kind of show off what it can do here Your weight scale part process here target max capacity You can set exactly how much the max that way if it doesn't make a mistake. It won't overdo it. So right now We're nine ten fluctuating down to six. I hate super heat It's why I prefer everything be stuff cooling and with a TXV But we're making it do we are doing it off the discharge Which you're supposed to do off the liquid line as you already know, but liquid line is probably hidden Somewhere back in there. It's got a crap Bristol compressor in there. We know that they aren't reliable surprisingly it's still running and This is a can't tell dates too far gone Far as discharge temperature what we're getting out of it. We've got our other sensor down there You can see up here that we have four Bluetooth Connected plus a phone All my test of stuff can be had a TrueTech tools from a code survival for 8% off You guys are interested in that stuff check out TrueTech tools links are stuff for down in the description down below Inter-survival save yourself 8% off your total order What I hear there's some exclusions, but that just depends on tool manufacturer It's nothing that TrueTech tools has going on. It's just manufacturer preferences on some things At least we're not flooding back. We're at seven degrees and it's coming back up I don't get too excited right now with the way that one is so we got 53 degree discharge I think we got 60 something coming back This is where it gets a little wonky Trying to do things That's coming back off of warm if that's the case. Let's stick the regular old thermometer in there See if we've got an issue going on here May have found our issue but it's freezing up Yeah, we're coming back 74 degrees Maybe it's finally reading that accurately now Okay, so maybe it was I was probably you know what it was. I was looking at wet bulb Can you believe that I made a mistake? Holy crap? So we are looking at true temperature. So there's the 117 So we got 53 out It can probably do the subtraction for you But I don't use this very often I'm doing mainly refrigeration anymore. So there's 338 so I don't really need it that often So it's just kind of need to show it off for the people that might be interested in it's a 74 53 minus 6 74. Let's just say it's 73. So 63 73. That's 20 21 degree rise there So we got a good rise We're not coming back to cold We're going out of a moderate decent rate there on that Running right in there at 13.2 on the super heat It's fluctuating some like I said, that's why I hate about super heat. So we're good on that Gonna go ahead and compare this top down top dawn. I guess Go ahead and turn it on hit the power button Go hit the hik micro hit the power button on it There's a hk micro coming on top dawn now You can see it's a bigger screen, but it's not really the effective measuring screen It's bigger. This is Android driven As you can see boom instantly hk micro is immediately ready to go And we've got it pointing out our hottest and our coldest spot Which this can do live video recording can't really I don't want to bother with trying to transfer this stuff That just sucks Glare is a freaking issue. There we go It just sucks So I'm not recording with that So going into the top dawn I Really don't like seeing myself in the picture. So go into there You can see it's window driven hit thermal imager This thing can do regular pictures all kinds of different stuff got a little bit of a splash screen there and you can see that same freaking reflections just mean it's it's it's a nice unit you can see that it's Picking up quite a bit of heat and what's going on there It's not quite the resolution that the From a long distance away, it's not got quite the resolution that the other ones got but It's a little cheaper You can see the heat on the compressor there Mean it's it's got some range the resolution is pretty much the same according to the spec sheet So when you compare the size of the screen it technically is about the same maybe just a little bit off Coming back to here. You it's finer detail on the you know the hik micro So you can see the same things with it. I hate the fact. It's getting me in that that glare There's just no good way to do it without Covering things up and then recording it's kind of difficult to hold them both you can see The outline a little better. This one here. I think has that It's definitely more vibrant, but I had the color turned down on the hik Hik Hik micro Both shown 158 149 Going to the center there center is 95 go to the center there 94 point 95.9. So they're both accurate far as in the center pointer No, just something I thought I'd show you guys I'll have links for it down below both of them This one here can be had on true tech tools that one there's an Amazon link Depending on what the price is because I know the hik the hik micro has gone up in cost. It used to be like 599 I got rid of the FLIR. I sold that fairly cheap That thing has gone up to over seven hundred dollars Just because I already have two of these now. I think we're good to go. We got 13 degrees there We've got that siliconed up and We've got that siliconed up. So we're good to go. Everything's put back together We're going to I recommended that we add a fan cycle control to it He said if it freezes up again, he'll do that I said alternatively you can also put a thermostat in the evaporator coil or on the suction line to shut it down So if it gets too cold and freezes up it can shut down But it make more sense to have the fan cycle control that way It should be able to cycle the fan preventing it from freezing up which would then actually keep it running They are doing things in there when it's probably moderate temperatures out So they are asking more of it. And so it's uh, it definitely would benefit from it Not my gas don't know where it came from chances are if somebody probably got it for him You can tell how full that is off of the Line right there. So it's a third fool. I'm going to give him a cap And tell him exactly that he's probably got about eight pounds in there and that he should probably put it inside That's going to wrap this one up guys haven't had a whole lot going on stuff I've been doing is just off the wall Stuff that either the video is going to be too long or Just may not be all that interesting to people But like I was saying guys these videos I do them because you guys watch them So I do want to say thank you so much. I'm finally into 30 30 some thousand subscribers range Which not everybody's watching all those videos So obviously I'd be getting 30 000 on every video if you would click notification bell that way You're actually notified that I've released them. So if you do enjoy them, you'll at least know that I've got one going on Honestly, thank you so much everybody that has been watching that leaves comments down below The people that leave the comments are the reason why I'm still doing this I make money at it But honestly the real reward I get is when I hear that It has helped somebody that was struggling or just people enjoy watching them because it takes a lot of time I mean, I'll have four or five hours in these videos editing them down by the time you get them Uploaded stuff like that. Yeah, you can do it on your phone things like that But you just don't have quite the same quality level and I want to make sure I cut all the dead spots and things like that Out of it that just makes it boring. I hate videos of drag on I try to make them quick as possible straight to the point. That's why when people miss things that I put in there and Say I didn't do some particular thing I know for a fact that they end up skipping ahead and then just hit the fast forward button which or that to the left Button and you can skip 5 10 15 20 seconds at a time So anyhow guys, I appreciate you all watching. I appreciate you subscribing and until next time. We'll catch you on the next one later
