WEBVTT 00:00:00.000 --> 00:00:03.600 Dude, I think I gotta stop impulse buying stuff the forum sends me. 00:00:03.600 --> 00:00:11.600 That's probably a good idea. I mean, on the one hand, who could resist the idea of doubling their environmental chamber testing capacity for such a low price? 00:00:11.600 --> 00:00:15.400 On the other hand, oh my god, it's huge! 00:00:15.400 --> 00:00:22.000 Did you guys know it was this big? Roughly. I knew it wouldn't fit under the fume hood we have. We'll see if it fits inside. 00:00:22.000 --> 00:00:25.500 Oh, this is gonna go well. That's as close as they can get. 00:00:25.500 --> 00:00:29.300 How are we supposed to move it once it's off the... like, can our forklift move it? 00:00:29.300 --> 00:00:33.500 No, not even close. I see. How are we moving it? 00:00:33.500 --> 00:00:39.000 That's a wonderful question, Linus. We're thinking maybe we drop it in the parking lot and then rent a forklift. 00:00:52.500 --> 00:00:56.200 I sincerely hope we didn't just buy someone else's garbage. 00:00:56.200 --> 00:01:01.600 It's apparently been stored outside for almost 10 years. The driver thinks it'll work on our little car dollies we have. 00:01:01.600 --> 00:01:06.000 They're good for about a ton and a half each. So he's gonna try to kind of back up, wiggle it into the doorway, 00:01:06.000 --> 00:01:10.000 and then we'll plant it onto those dollies and kind of hope for the best. 00:01:10.000 --> 00:01:13.100 How are we gonna get it off the dollies? That's future problem. 00:01:13.100 --> 00:01:19.000 We can probably test our existing environmental chamber inside of this one. 00:01:19.000 --> 00:01:26.300 I was thinking it didn't look that big. And I was thinking, hey, I mean, a low ball bid can't hurt, right? 00:01:26.300 --> 00:01:29.700 We only paid 1,300 bucks for it, I think? Something like that. 00:01:29.700 --> 00:01:33.500 So bottom line, we're paying a tenth of what we paid for our existing environmental chamber, 00:01:33.500 --> 00:01:37.300 even including the delivery. But we haven't fixed it up yet. Here's the issue. 00:01:37.300 --> 00:01:42.400 While the seller does believe it to be in working order, it certainly isn't in working order right now. 00:01:42.400 --> 00:01:46.800 All of the refrigerant was drained years ago and replaced with an inert gas, 00:01:46.800 --> 00:01:51.400 and it has been stored idle for almost a decade outside. 00:01:51.400 --> 00:01:56.100 We use our current environmental chamber for testing products that are sensitive to changes in temperature 00:01:56.100 --> 00:02:00.000 or humidity like power supplies or anything with a battery, 00:02:00.000 --> 00:02:03.200 as well as to conduct wacky science fair experiments. 00:02:03.200 --> 00:02:07.600 It's been great. The only issue is that sometimes it's a little bit on the small side, 00:02:07.600 --> 00:02:13.100 and since we only have one, it can be a bit of a production and testing bottleneck. 00:02:13.100 --> 00:02:17.500 I really don't know if that was the solution though. This is the plan. 00:02:17.500 --> 00:02:21.400 That's the plan. That's our best plan. 00:02:21.400 --> 00:02:24.800 Were we able to find an MSRP on this? Not so far. 00:02:24.800 --> 00:02:30.400 The company's been sold two or three times, and so we only have a generic service manual. 00:02:30.400 --> 00:02:33.600 Oh, no. Well, really? Yeah. Do we know what year it's from? 00:02:33.600 --> 00:02:37.000 2008, I think. Good year. 00:02:37.000 --> 00:02:41.400 Solid year. Do we have a plan for when this is up and running, 00:02:41.400 --> 00:02:44.500 or are we assuming nothing for now? I was kind of assuming nothing. 00:02:44.500 --> 00:02:49.000 I wasn't, like, planning any projects for next month or anything. I think the plan is, the line is, bought this thing now, what? 00:02:49.000 --> 00:02:51.900 It's amazing how many things have that plan around here. 00:02:52.100 --> 00:02:55.100 Someone work out that TV wall, phenomenal. 00:02:55.100 --> 00:02:58.200 Right? Phenomenal. This, maybe. 00:02:58.200 --> 00:03:01.300 I'm one for something. 00:03:01.300 --> 00:03:05.900 What did we pay for the other one? I think that one was somewhere between $30,000 and $40,000. 00:03:05.900 --> 00:03:09.400 Okay. So we would have to spend an awful lot refurbing this thing 00:03:09.400 --> 00:03:12.400 before we would be behind the eight ball on it. Do you know how much the gas costs? 00:03:12.400 --> 00:03:17.700 No. Oh, is the gas really expensive? One of the gases we have to buy is $4,000. 00:03:17.700 --> 00:03:21.300 Shut up. We have to buy a whole cylinder. That's just the gas, not their time to fill it. 00:03:21.300 --> 00:03:24.500 Why do we have to buy a whole cylinder? I don't know. That's not Alex's question. 00:03:24.500 --> 00:03:31.000 Because that's all, that's the lowest amount they'll sell it in. The techs have the easier to get gas, but they don't have this one. 00:03:31.000 --> 00:03:37.800 This one, they have to get from, like, a specialty supplier. And the supplier will only sell it in full tanks. 00:03:37.800 --> 00:03:41.000 Oh, okay. But we could sell the partial tank after. 00:03:41.000 --> 00:03:44.200 Maybe, unless we use it all. I think the tank's five kilograms. 00:03:44.200 --> 00:03:47.400 So we might need more than one tank. We might, hopefully not. 00:03:47.400 --> 00:03:50.900 The other one is 15 pounds worth of refrigerant. That one? No, no, no. 00:03:50.900 --> 00:03:54.300 Oh. This is two-stage, so it has... It's two-stage? 00:03:54.300 --> 00:03:59.600 Yeah, it's got two different refrigerants in it. Okay, I knew absolutely nothing about it other than, 00:03:59.600 --> 00:04:03.100 seems like a cheap environmental chamber. So does it go, like, lower in temperature? 00:04:03.100 --> 00:04:06.200 I think it's negative 177. So... Shut up. 00:04:06.200 --> 00:04:09.700 Really? I think. What? 00:04:12.700 --> 00:04:16.000 It's not going to fit under here. No, it really isn't. I mean... 00:04:16.000 --> 00:04:19.000 No, it really isn't. Does it do humidity control as well? 00:04:19.000 --> 00:04:22.600 Do you know? It must. It takes plumbing as well, so it's water. Okay. 00:04:22.600 --> 00:04:26.400 So it must do. Oh yeah, yes, paper and plumber too. Could, like, I get inside it? 00:04:26.400 --> 00:04:29.700 Oh, definitely. I imagine, yeah. What about you? 00:04:29.700 --> 00:04:36.900 I couldn't stand it, but I could probably fit in there. The size is one standing Linus or one folded Lucas. 00:04:36.900 --> 00:04:42.200 Oh my God. So that display interface on the side is cooked, hey? 00:04:42.200 --> 00:04:46.500 I haven't really looked. You know, do you really need to stand on a curb next to me? 00:04:46.500 --> 00:04:48.900 I'll take a knee. It's bad enough as it is. 00:04:55.900 --> 00:05:00.800 This may be the point where I start questioning the choice. I mean, at the price, it seems so obvious, 00:05:00.800 --> 00:05:04.000 but clearly nobody else bit above this. Yeah. 00:05:04.000 --> 00:05:07.700 I said don't fit more than it's worth in scrap metal, so... 00:05:07.700 --> 00:05:11.500 Okay, nobody told me that. They weren't kidding. 00:05:11.500 --> 00:05:12.600 That was the plan. 00:05:17.400 --> 00:05:21.400 How much you want to bet that display doesn't work? Oh yeah, there's no way. 00:05:21.400 --> 00:05:25.500 How are we going to get replacement parts? That's a you problem, isn't it? 00:05:25.500 --> 00:05:29.200 No. Damn. I think he's going to lift this just the end up and scoot it in. 00:05:29.200 --> 00:05:33.500 Oh, we've got a forklift here now. Those, the pallets, like, 2x6s is I think. 00:05:33.500 --> 00:05:37.200 I just noticed the pallets made of 2x6s, I think. 00:05:37.200 --> 00:05:39.400 They're just shredding. Just... 00:05:41.400 --> 00:05:45.300 This is ridiculous. So it seems what they're trying to do is 00:05:45.300 --> 00:05:50.600 lift her up a little bit with the forklift to take enough strain off of those little rollers 00:05:50.600 --> 00:05:54.500 that we can get it over the lip. I don't know if it's going to work. 00:05:54.500 --> 00:05:58.300 There we go. Oh. It worked. 00:06:03.500 --> 00:06:09.600 Oh, okay. Putting the cables up against the thing in front of the bay door was a strategic choice. 00:06:09.600 --> 00:06:16.300 I thought it was an accident before. I feel like we may have been better off with the rollers in the middle to 4x4s. 00:06:16.300 --> 00:06:20.200 Maybe I should say something before we completely unstrap it. 00:06:20.200 --> 00:06:23.900 Right now, the pallet is bowing in the middle. 00:06:23.900 --> 00:06:29.800 Would we be better off taking the rollers and putting them on the middle 4x4s? 00:06:29.800 --> 00:06:36.900 Uh, I mean, maybe. Well, I just mean if the whole idea is that these rollers are going to lift the thing, 00:06:36.900 --> 00:06:40.500 then we might as well put them in a position where they're not going to... 00:06:40.500 --> 00:06:44.100 Yeah, because we're going to have to run to forklift to get this thing off anyway. 00:06:44.100 --> 00:06:47.600 Because I just think it might roll a lot easier because we'll have the mass over the rollers. 00:06:47.600 --> 00:06:53.800 Yeah, no, I think you're right. Okay, cool. As long as the pallet survives being lifted one more time. 00:06:57.700 --> 00:07:01.200 Wait, wait, wait. It's not in the right spot over there. That way. 00:07:01.200 --> 00:07:08.200 It turns out supervising is a job. Yeah, I think now the pallet is more off the... 00:07:08.200 --> 00:07:11.700 It's off the ground now because it was getting hung up in the middle there. 00:07:11.700 --> 00:07:14.800 And that's it. We're kind of dragging. 00:07:14.800 --> 00:07:18.900 Oh, Alex. I think this bent. 00:07:18.900 --> 00:07:22.100 Like, I just don't think it has the weight anymore. Oh, yeah. 00:07:22.100 --> 00:07:26.400 Yeah, the car dolly totally just bent. Yeah, that's why. I mean, should we... 00:07:26.400 --> 00:07:30.900 Should we look at it? That's a satisfying handle, hey? 00:07:35.700 --> 00:07:38.700 What the... It's like a baseball. 00:07:38.700 --> 00:07:41.800 I like the two-man lift logo. Yeah, yeah, yeah. 00:07:41.800 --> 00:07:45.900 Yeah, two-man lift. This panel. Yeah. 00:07:53.900 --> 00:07:57.700 So here's our fans that blow through the evap. 00:07:57.700 --> 00:08:02.600 And then it comes out like this. This seems to be humidity control. 00:08:02.600 --> 00:08:05.600 They kind of look like sprinkler heads or something. 00:08:05.600 --> 00:08:11.100 Well, time for us to do some learning. I like that you cut reusable straps. 00:08:11.100 --> 00:08:15.900 Oh, what? Okay. So she's a little beefier than the old one. 00:08:15.900 --> 00:08:20.900 Oh my God, this is going to be a hell of a project. Like, all that plumbing for sure has to come out. 00:08:20.900 --> 00:08:24.600 Look at it. Look at the color of it, Lucas. 00:08:24.600 --> 00:08:28.100 You know, all things considered though, it's not that rusty. 00:08:28.100 --> 00:08:33.400 Oh, gross. Yeah, the plumbing has to come out for sure. 00:08:33.900 --> 00:08:37.800 Oh, here's another access panel. Pressure gauge. 00:08:37.800 --> 00:08:41.100 I know what that is. Moisture release thing. 00:08:41.100 --> 00:08:45.200 Those are, I can't remember the name, but they are magnetic 00:08:45.200 --> 00:08:48.900 and they start and stop flow. Ah, I appear to be tethered. 00:08:48.900 --> 00:08:52.200 No one leaped to my aid at once. You didn't ask for help. 00:08:52.200 --> 00:08:56.300 Okay, cool. Ah, you have got to be kidding me. 00:08:56.300 --> 00:08:59.900 Are these the compressors? Holy crap. 00:08:59.900 --> 00:09:04.400 The compressors themselves have cooling fans that ask 00:09:04.400 --> 00:09:08.300 for freaking 208 volt, 1.3 amp. 00:09:08.300 --> 00:09:12.100 The compressors have 250 watt cooling fans. 00:09:12.100 --> 00:09:16.400 Freakin' what? Okay, there's got to be a heat exchanger in here somewhere. 00:09:18.400 --> 00:09:21.500 Oh, fiberglass, yuck. Okay, a little rusty, a little dusty. 00:09:21.500 --> 00:09:25.300 Condenser water inlet. Oh, the whole thing is liquid cooled. 00:09:25.300 --> 00:09:28.600 There's no, there's no like air cooled fan condenser. 00:09:28.600 --> 00:09:33.200 Like, I don't, I don't see one. So there's, there's the water inlet. So the plumbing is not necessarily just 00:09:33.200 --> 00:09:38.200 for humidity control, it's for cooling. So we are going to have to have like a cooling tower 00:09:38.200 --> 00:09:42.700 or something. Wait, do we still have a bunch of those big radiators 00:09:42.700 --> 00:09:46.700 and those like server rack things? Yeah, we do, yeah. I mean, we're going to have to figure out what kind 00:09:46.700 --> 00:09:52.900 of capacity we need, but oh boy. This right here is my condenser for which one? 00:09:52.900 --> 00:09:56.600 Oh, maybe it's both. Broad strokes, I think I figured out the flow path. 00:09:56.600 --> 00:10:02.400 That back there is our first stage compressor. It's cooled by this liquid cooled condenser 00:10:02.400 --> 00:10:06.300 that we're going to have to have water hookups to this chamber in order to operate. 00:10:06.300 --> 00:10:10.600 That cools through this heat exchanger right here, 00:10:10.600 --> 00:10:13.800 the hot side of my second stage compressor, 00:10:13.800 --> 00:10:19.200 which is over there. That guy uses this giant effectively reservoir 00:10:19.200 --> 00:10:26.600 to store the gaseous refrigerant when the system isn't running. Wait, huh, it's also when it is running. 00:10:26.600 --> 00:10:30.500 It's kind of complicated. The accumulator also plays a crucial role 00:10:30.500 --> 00:10:34.900 in preventing liquid from entering the compressor in the first place. You should just check out our recent video 00:10:34.900 --> 00:10:39.300 about the three stage children if you want to learn more. All right. 00:10:39.300 --> 00:10:42.400 The cold side of that boy comes right up here 00:10:42.400 --> 00:10:46.000 and goes, there we go, into the evaporator 00:10:46.000 --> 00:10:50.400 inside the chamber. So the operating range was what, negative 77 to 170? 00:10:50.400 --> 00:10:53.900 She's not as fast as our existing chamber, but a big part of the reason for that 00:10:53.900 --> 00:10:57.700 is the internal volume has got to be six-tip 8x, 00:10:57.700 --> 00:11:02.700 the other one, so we could easily test like a large system in here. 00:11:02.700 --> 00:11:06.300 If we can get it working, boy, are there ever a lot of little parts 00:11:06.300 --> 00:11:10.600 that are looking rusted shut. Feel free to tell me I'm wrong about any of this, you guys. 00:11:10.600 --> 00:11:14.400 I know just enough about the refrigeration cycle to be dangerous. You'll have to get a little taller. 00:11:14.400 --> 00:11:18.100 Wolf? Come on, there we go. 00:11:18.100 --> 00:11:25.700 Oh, well, that was anticlimactic. Are these the motors for the internal fans? 00:11:25.800 --> 00:11:29.600 575 volts, two amps. 00:11:29.600 --> 00:11:35.200 These are 1,000-watt fan motors. About a horsepower and a half. 00:11:37.200 --> 00:11:41.600 Each! Z-Arc. Oh, look at the size of those guys. 00:11:41.600 --> 00:11:44.900 Oh, there's a PC in here. There sure is. 00:11:44.900 --> 00:11:48.300 What are the flipping odds that that works? 00:11:48.300 --> 00:11:51.800 Windows Vista Business Edition. Found the keys to the city. 00:11:51.800 --> 00:11:54.900 You got a Dell. Dude! Same thing as the bottom, though. 00:11:54.900 --> 00:11:59.400 There's far less corrosion in here than I expected. It must have been at least under cover outside. 00:11:59.400 --> 00:12:02.800 This seems like probably the way to do things. 00:12:02.800 --> 00:12:07.300 Oh, my God, there's a lot of time back here. Wait, is that a RAM stick? 00:12:07.300 --> 00:12:10.700 Old-timey automation? The f**k is this? 00:12:10.700 --> 00:12:15.300 Oh, Jesus. Okay, this is another computer. What about second computer? 00:12:15.300 --> 00:12:18.300 Why, you're in the schematic here. I'm what? 00:12:18.300 --> 00:12:22.500 You're in the schematic. Oh, stop it. L-S, small. 00:12:22.500 --> 00:12:25.900 Wait a second. Jordan, you hooked up the Dell? I did. 00:12:25.900 --> 00:12:28.900 I mean, dude, if you're going to get a Dell, you got to know if your Dell works, right? 00:12:28.900 --> 00:12:32.100 Exactly. So this looks like an old Celeron. Vista Business. 00:12:32.100 --> 00:12:36.100 And most of the interaction with the computer stuff here is all serial. 00:12:36.100 --> 00:12:39.100 Okay. Dan by LED is on. 00:12:39.100 --> 00:12:43.300 Yeah. That's a good sign. Well, that's not a good sign. Well, let's solve it now. 00:12:43.300 --> 00:12:47.300 Oh, was it flashing before? I don't know. Who makes an orange power LED, though? 00:12:47.300 --> 00:12:51.500 There's no way. Oh, this is BTX. Okay, stupid question. 00:12:51.500 --> 00:12:55.400 Is that power button even hooked up? If it's meant to be turned on somehow, else here. 00:12:55.400 --> 00:13:01.600 That is a not stupid question. For future us, very cool piece of equipment. 00:13:01.600 --> 00:13:05.600 I'm glad we didn't pay full price for it in its current condition, though, because there's no way that this is alive. 00:13:05.600 --> 00:13:09.600 I mean, wait, does it have a power plug? 00:13:09.600 --> 00:13:13.100 Sorry. Sorry. It's still good. Ah, it's this. 00:13:13.100 --> 00:13:16.500 Okay, here, let's power it. Oh, dude. 00:13:16.500 --> 00:13:19.600 No way. Dude. No way. The display works. 00:13:19.600 --> 00:13:23.500 Are you kidding me right now? Dude, she works. 00:13:23.500 --> 00:13:26.900 To be clear, I'm not worried that we would be able to find, you know, 00:13:26.900 --> 00:13:31.000 another display with similar inputs. I'm just worried that using something 00:13:31.000 --> 00:13:34.000 that's not part of the expected equipment for this thing 00:13:34.000 --> 00:13:37.300 could have unforeseen consequences. This is a relief for me, 00:13:37.300 --> 00:13:40.900 because this is the interface. When you don't have an interface, you got nothing. 00:13:40.900 --> 00:13:44.300 At least we got a big nothing. Yeah. Oh, what's this? 00:13:44.300 --> 00:13:47.900 Documentation, apparently. I think I found that it uses two different refrigerants, 00:13:47.900 --> 00:13:51.200 so that checks out. Okay, that makes it definitely a two-stage. 00:13:51.200 --> 00:13:55.000 It's got, you know, up-to-date calibration or maintenance records from 2014. 00:13:55.000 --> 00:13:58.600 She seems like a pretty good manual. Ellen, two cooling. Whoa, whoa, whoa, whoa, whoa, whoa. 00:13:58.600 --> 00:14:02.600 It's saying if you want to additionally use liquid nitrogen cooling, there's a vent. 00:14:02.600 --> 00:14:05.900 So you should vent. We can get the quantum computing in there. 00:14:05.900 --> 00:14:10.300 Yeah. There's a lot to learn, but this does not look like a generic manual. 00:14:10.300 --> 00:14:15.200 This looks like the proper manual for this chamber. For this one, yeah. That's actually very promising, then, I guess. 00:14:15.200 --> 00:14:20.000 And it has some, like, schematics on the back for some electrical and stuff you can see. 00:14:20.000 --> 00:14:23.900 Dude, without this, we'd probably be S.O.I. That would be so lost, yeah. We might still be lost, but... 00:14:23.900 --> 00:14:28.000 Cool. Got a lot to learn. And this is going to be a huge project. 00:14:28.000 --> 00:14:33.500 In short, that we know of so far, we need to get some kind of external cooling tower. 00:14:33.500 --> 00:14:36.900 We need to charge the refrigerant in both of the stages. 00:14:36.900 --> 00:14:39.900 We need to go through and inspect for any failed valves 00:14:39.900 --> 00:14:44.400 or sensors or other components. We need to replace the PC and also figure out 00:14:44.400 --> 00:14:51.200 what kind of control software they were using. And we need to find a place to put it and a way to move it. 00:14:51.200 --> 00:14:55.200 Whew. And we also have to tell you about our sponsor. 00:14:55.200 --> 00:14:59.300 If you guys enjoyed this video, make sure you subscribe for the rest of our adventure. 00:14:59.300 --> 00:15:03.900 Hopefully getting this thing into service. And if you want to check out another refrigeration video, 00:15:03.900 --> 00:15:08.300 why not check out the time that I bought the world's greatest CPU cooler? 00:15:08.300 --> 00:15:11.700 It's not just two-stage, but it's a three-stage cascade 00:15:11.700 --> 00:15:16.300 chiller that goes directly onto a CPU and brings it down to negative 100 Celsius. 00:15:16.300 --> 00:15:20.800 It's pretty cool. What do you think was the worst in scrap? Hopefully more than $1,300.
