1
00:00:00,000 --> 00:00:03,600
Dude, I think I gotta stop impulse buying stuff the forum sends me.

2
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?

3
00:00:11,600 --> 00:00:15,400
On the other hand, oh my god, it's huge!

4
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.

5
00:00:22,000 --> 00:00:25,500
Oh, this is gonna go well. That's as close as they can get.

6
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?

7
00:00:29,300 --> 00:00:33,500
No, not even close. I see. How are we moving it?

8
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.

9
00:00:52,500 --> 00:00:56,200
I sincerely hope we didn't just buy someone else's garbage.

10
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.

11
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,

12
00:01:06,000 --> 00:01:10,000
and then we'll plant it onto those dollies and kind of hope for the best.

13
00:01:10,000 --> 00:01:13,100
How are we gonna get it off the dollies? That's future problem.

14
00:01:13,100 --> 00:01:19,000
We can probably test our existing environmental chamber inside of this one.

15
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?

16
00:01:26,300 --> 00:01:29,700
We only paid 1,300 bucks for it, I think? Something like that.

17
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,

18
00:01:33,500 --> 00:01:37,300
even including the delivery. But we haven't fixed it up yet. Here's the issue.

19
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.

20
00:01:42,400 --> 00:01:46,800
All of the refrigerant was drained years ago and replaced with an inert gas,

21
00:01:46,800 --> 00:01:51,400
and it has been stored idle for almost a decade outside.

22
00:01:51,400 --> 00:01:56,100
We use our current environmental chamber for testing products that are sensitive to changes in temperature

23
00:01:56,100 --> 00:02:00,000
or humidity like power supplies or anything with a battery,

24
00:02:00,000 --> 00:02:03,200
as well as to conduct wacky science fair experiments.

25
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,

26
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.

27
00:02:13,100 --> 00:02:17,500
I really don't know if that was the solution though. This is the plan.

28
00:02:17,500 --> 00:02:21,400
That's the plan. That's our best plan.

29
00:02:21,400 --> 00:02:24,800
Were we able to find an MSRP on this? Not so far.

30
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.

31
00:02:30,400 --> 00:02:33,600
Oh, no. Well, really? Yeah. Do we know what year it's from?

32
00:02:33,600 --> 00:02:37,000
2008, I think. Good year.

33
00:02:37,000 --> 00:02:41,400
Solid year. Do we have a plan for when this is up and running,

34
00:02:41,400 --> 00:02:44,500
or are we assuming nothing for now? I was kind of assuming nothing.

35
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?

36
00:02:49,000 --> 00:02:51,900
It's amazing how many things have that plan around here.

37
00:02:52,100 --> 00:02:55,100
Someone work out that TV wall, phenomenal.

38
00:02:55,100 --> 00:02:58,200
Right? Phenomenal. This, maybe.

39
00:02:58,200 --> 00:03:01,300
I'm one for something.

40
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.

41
00:03:05,900 --> 00:03:09,400
Okay. So we would have to spend an awful lot refurbing this thing

42
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?

43
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.

44
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.

45
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.

46
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.

47
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.

48
00:03:37,800 --> 00:03:41,000
Oh, okay. But we could sell the partial tank after.

49
00:03:41,000 --> 00:03:44,200
Maybe, unless we use it all. I think the tank's five kilograms.

50
00:03:44,200 --> 00:03:47,400
So we might need more than one tank. We might, hopefully not.

51
00:03:47,400 --> 00:03:50,900
The other one is 15 pounds worth of refrigerant. That one? No, no, no.

52
00:03:50,900 --> 00:03:54,300
Oh. This is two-stage, so it has... It's two-stage?

53
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,

54
00:03:59,600 --> 00:04:03,100
seems like a cheap environmental chamber. So does it go, like, lower in temperature?

55
00:04:03,100 --> 00:04:06,200
I think it's negative 177. So... Shut up.

56
00:04:06,200 --> 00:04:09,700
Really? I think. What?

57
00:04:12,700 --> 00:04:16,000
It's not going to fit under here. No, it really isn't. I mean...

58
00:04:16,000 --> 00:04:19,000
No, it really isn't. Does it do humidity control as well?

59
00:04:19,000 --> 00:04:22,600
Do you know? It must. It takes plumbing as well, so it's water. Okay.

60
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?

61
00:04:26,400 --> 00:04:29,700
Oh, definitely. I imagine, yeah. What about you?

62
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.

63
00:04:36,900 --> 00:04:42,200
Oh my God. So that display interface on the side is cooked, hey?

64
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?

65
00:04:46,500 --> 00:04:48,900
I'll take a knee. It's bad enough as it is.

66
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,

67
00:05:00,800 --> 00:05:04,000
but clearly nobody else bit above this. Yeah.

68
00:05:04,000 --> 00:05:07,700
I said don't fit more than it's worth in scrap metal, so...

69
00:05:07,700 --> 00:05:11,500
Okay, nobody told me that. They weren't kidding.

70
00:05:11,500 --> 00:05:12,600
That was the plan.

71
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.

72
00:05:21,400 --> 00:05:25,500
How are we going to get replacement parts? That's a you problem, isn't it?

73
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.

74
00:05:29,200 --> 00:05:33,500
Oh, we've got a forklift here now. Those, the pallets, like, 2x6s is I think.

75
00:05:33,500 --> 00:05:37,200
I just noticed the pallets made of 2x6s, I think.

76
00:05:37,200 --> 00:05:39,400
They're just shredding. Just...

77
00:05:41,400 --> 00:05:45,300
This is ridiculous. So it seems what they're trying to do is

78
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

79
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.

80
00:05:54,500 --> 00:05:58,300
There we go. Oh. It worked.

81
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.

82
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.

83
00:06:16,300 --> 00:06:20,200
Maybe I should say something before we completely unstrap it.

84
00:06:20,200 --> 00:06:23,900
Right now, the pallet is bowing in the middle.

85
00:06:23,900 --> 00:06:29,800
Would we be better off taking the rollers and putting them on the middle 4x4s?

86
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,

87
00:06:36,900 --> 00:06:40,500
then we might as well put them in a position where they're not going to...

88
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.

89
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.

90
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.

91
00:06:57,700 --> 00:07:01,200
Wait, wait, wait. It's not in the right spot over there. That way.

92
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...

93
00:07:08,200 --> 00:07:11,700
It's off the ground now because it was getting hung up in the middle there.

94
00:07:11,700 --> 00:07:14,800
And that's it. We're kind of dragging.

95
00:07:14,800 --> 00:07:18,900
Oh, Alex. I think this bent.

96
00:07:18,900 --> 00:07:22,100
Like, I just don't think it has the weight anymore. Oh, yeah.

97
00:07:22,100 --> 00:07:26,400
Yeah, the car dolly totally just bent. Yeah, that's why. I mean, should we...

98
00:07:26,400 --> 00:07:30,900
Should we look at it? That's a satisfying handle, hey?

99
00:07:35,700 --> 00:07:38,700
What the... It's like a baseball.

100
00:07:38,700 --> 00:07:41,800
I like the two-man lift logo. Yeah, yeah, yeah.

101
00:07:41,800 --> 00:07:45,900
Yeah, two-man lift. This panel. Yeah.

102
00:07:53,900 --> 00:07:57,700
So here's our fans that blow through the evap.

103
00:07:57,700 --> 00:08:02,600
And then it comes out like this. This seems to be humidity control.

104
00:08:02,600 --> 00:08:05,600
They kind of look like sprinkler heads or something.

105
00:08:05,600 --> 00:08:11,100
Well, time for us to do some learning. I like that you cut reusable straps.

106
00:08:11,100 --> 00:08:15,900
Oh, what? Okay. So she's a little beefier than the old one.

107
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.

108
00:08:20,900 --> 00:08:24,600
Look at it. Look at the color of it, Lucas.

109
00:08:24,600 --> 00:08:28,100
You know, all things considered though, it's not that rusty.

110
00:08:28,100 --> 00:08:33,400
Oh, gross. Yeah, the plumbing has to come out for sure.

111
00:08:33,900 --> 00:08:37,800
Oh, here's another access panel. Pressure gauge.

112
00:08:37,800 --> 00:08:41,100
I know what that is. Moisture release thing.

113
00:08:41,100 --> 00:08:45,200
Those are, I can't remember the name, but they are magnetic

114
00:08:45,200 --> 00:08:48,900
and they start and stop flow. Ah, I appear to be tethered.

115
00:08:48,900 --> 00:08:52,200
No one leaped to my aid at once. You didn't ask for help.

116
00:08:52,200 --> 00:08:56,300
Okay, cool. Ah, you have got to be kidding me.

117
00:08:56,300 --> 00:08:59,900
Are these the compressors? Holy crap.

118
00:08:59,900 --> 00:09:04,400
The compressors themselves have cooling fans that ask

119
00:09:04,400 --> 00:09:08,300
for freaking 208 volt, 1.3 amp.

120
00:09:08,300 --> 00:09:12,100
The compressors have 250 watt cooling fans.

121
00:09:12,100 --> 00:09:16,400
Freakin' what? Okay, there's got to be a heat exchanger in here somewhere.

122
00:09:18,400 --> 00:09:21,500
Oh, fiberglass, yuck. Okay, a little rusty, a little dusty.

123
00:09:21,500 --> 00:09:25,300
Condenser water inlet. Oh, the whole thing is liquid cooled.

124
00:09:25,300 --> 00:09:28,600
There's no, there's no like air cooled fan condenser.

125
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

126
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

127
00:09:38,200 --> 00:09:42,700
or something. Wait, do we still have a bunch of those big radiators

128
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

129
00:09:46,700 --> 00:09:52,900
of capacity we need, but oh boy. This right here is my condenser for which one?

130
00:09:52,900 --> 00:09:56,600
Oh, maybe it's both. Broad strokes, I think I figured out the flow path.

131
00:09:56,600 --> 00:10:02,400
That back there is our first stage compressor. It's cooled by this liquid cooled condenser

132
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.

133
00:10:06,300 --> 00:10:10,600
That cools through this heat exchanger right here,

134
00:10:10,600 --> 00:10:13,800
the hot side of my second stage compressor,

135
00:10:13,800 --> 00:10:19,200
which is over there. That guy uses this giant effectively reservoir

136
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.

137
00:10:26,600 --> 00:10:30,500
It's kind of complicated. The accumulator also plays a crucial role

138
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

139
00:10:34,900 --> 00:10:39,300
about the three stage children if you want to learn more. All right.

140
00:10:39,300 --> 00:10:42,400
The cold side of that boy comes right up here

141
00:10:42,400 --> 00:10:46,000
and goes, there we go, into the evaporator

142
00:10:46,000 --> 00:10:50,400
inside the chamber. So the operating range was what, negative 77 to 170?

143
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

144
00:10:53,900 --> 00:10:57,700
is the internal volume has got to be six-tip 8x,

145
00:10:57,700 --> 00:11:02,700
the other one, so we could easily test like a large system in here.

146
00:11:02,700 --> 00:11:06,300
If we can get it working, boy, are there ever a lot of little parts

147
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.

148
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.

149
00:11:14,400 --> 00:11:18,100
Wolf? Come on, there we go.

150
00:11:18,100 --> 00:11:25,700
Oh, well, that was anticlimactic. Are these the motors for the internal fans?

151
00:11:25,800 --> 00:11:29,600
575 volts, two amps.

152
00:11:29,600 --> 00:11:35,200
These are 1,000-watt fan motors. About a horsepower and a half.

153
00:11:37,200 --> 00:11:41,600
Each! Z-Arc. Oh, look at the size of those guys.

154
00:11:41,600 --> 00:11:44,900
Oh, there's a PC in here. There sure is.

155
00:11:44,900 --> 00:11:48,300
What are the flipping odds that that works?

156
00:11:48,300 --> 00:11:51,800
Windows Vista Business Edition. Found the keys to the city.

157
00:11:51,800 --> 00:11:54,900
You got a Dell. Dude! Same thing as the bottom, though.

158
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.

159
00:11:59,400 --> 00:12:02,800
This seems like probably the way to do things.

160
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?

161
00:12:07,300 --> 00:12:10,700
Old-timey automation? The f**k is this?

162
00:12:10,700 --> 00:12:15,300
Oh, Jesus. Okay, this is another computer. What about second computer?

163
00:12:15,300 --> 00:12:18,300
Why, you're in the schematic here. I'm what?

164
00:12:18,300 --> 00:12:22,500
You're in the schematic. Oh, stop it. L-S, small.

165
00:12:22,500 --> 00:12:25,900
Wait a second. Jordan, you hooked up the Dell? I did.

166
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?

167
00:12:28,900 --> 00:12:32,100
Exactly. So this looks like an old Celeron. Vista Business.

168
00:12:32,100 --> 00:12:36,100
And most of the interaction with the computer stuff here is all serial.

169
00:12:36,100 --> 00:12:39,100
Okay. Dan by LED is on.

170
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.

171
00:12:43,300 --> 00:12:47,300
Oh, was it flashing before? I don't know. Who makes an orange power LED, though?

172
00:12:47,300 --> 00:12:51,500
There's no way. Oh, this is BTX. Okay, stupid question.

173
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.

174
00:12:55,400 --> 00:13:01,600
That is a not stupid question. For future us, very cool piece of equipment.

175
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.

176
00:13:05,600 --> 00:13:09,600
I mean, wait, does it have a power plug?

177
00:13:09,600 --> 00:13:13,100
Sorry. Sorry. It's still good. Ah, it's this.

178
00:13:13,100 --> 00:13:16,500
Okay, here, let's power it. Oh, dude.

179
00:13:16,500 --> 00:13:19,600
No way. Dude. No way. The display works.

180
00:13:19,600 --> 00:13:23,500
Are you kidding me right now? Dude, she works.

181
00:13:23,500 --> 00:13:26,900
To be clear, I'm not worried that we would be able to find, you know,

182
00:13:26,900 --> 00:13:31,000
another display with similar inputs. I'm just worried that using something

183
00:13:31,000 --> 00:13:34,000
that's not part of the expected equipment for this thing

184
00:13:34,000 --> 00:13:37,300
could have unforeseen consequences. This is a relief for me,

185
00:13:37,300 --> 00:13:40,900
because this is the interface. When you don't have an interface, you got nothing.

186
00:13:40,900 --> 00:13:44,300
At least we got a big nothing. Yeah. Oh, what's this?

187
00:13:44,300 --> 00:13:47,900
Documentation, apparently. I think I found that it uses two different refrigerants,

188
00:13:47,900 --> 00:13:51,200
so that checks out. Okay, that makes it definitely a two-stage.

189
00:13:51,200 --> 00:13:55,000
It's got, you know, up-to-date calibration or maintenance records from 2014.

190
00:13:55,000 --> 00:13:58,600
She seems like a pretty good manual. Ellen, two cooling. Whoa, whoa, whoa, whoa, whoa, whoa.

191
00:13:58,600 --> 00:14:02,600
It's saying if you want to additionally use liquid nitrogen cooling, there's a vent.

192
00:14:02,600 --> 00:14:05,900
So you should vent. We can get the quantum computing in there.

193
00:14:05,900 --> 00:14:10,300
Yeah. There's a lot to learn, but this does not look like a generic manual.

194
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.

195
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.

196
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...

197
00:14:23,900 --> 00:14:28,000
Cool. Got a lot to learn. And this is going to be a huge project.

198
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.

199
00:14:33,500 --> 00:14:36,900
We need to charge the refrigerant in both of the stages.

200
00:14:36,900 --> 00:14:39,900
We need to go through and inspect for any failed valves

201
00:14:39,900 --> 00:14:44,400
or sensors or other components. We need to replace the PC and also figure out

202
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.

203
00:14:51,200 --> 00:14:55,200
Whew. And we also have to tell you about our sponsor.

204
00:14:55,200 --> 00:14:59,300
If you guys enjoyed this video, make sure you subscribe for the rest of our adventure.

205
00:14:59,300 --> 00:15:03,900
Hopefully getting this thing into service. And if you want to check out another refrigeration video,

206
00:15:03,900 --> 00:15:08,300
why not check out the time that I bought the world's greatest CPU cooler?

207
00:15:08,300 --> 00:15:11,700
It's not just two-stage, but it's a three-stage cascade

208
00:15:11,700 --> 00:15:16,300
chiller that goes directly onto a CPU and brings it down to negative 100 Celsius.

209
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.
