The amount of Canuckistanian drawl coming from Brian's mouth is freaking hilarious

hey you guys what refrigerant is in this airconditioner? if you guys change it to r507 or r404 you can reach much deeper temps fyi. Heck even r290 Propane would work better than r407 what i think is in this unit.

 

i worked in the airconditioning industrie in germany its my what do you guys call it a education and training thing  we call it an "Ausbildung".

They're using R410A from what I understand which is a HBP refrigerant which is why the unit performs so poorly, they're also not using a correct metering device either, a crimped tube is pretty awful. A correctly sized capillary tube would be much better, or better yet us an EEV.

Yes i would sign that.

Really enjoyed this video! I love these types of experimental, “let’s see what happens” videos that take place in the workshop. Would love to see more like this!

Always fun how complicated it can be to dumb down an AC unit, or other electronics for that matter.

 

It can be a fun challenge at times, but truly something that one shouldn't attempt unless one has a good few years of experience with electronics.

 

Though, this chip doesn't really have an "enable" pin, or rather, it is likely some transistor array that needs a bit more fancy control signals than a crude on/off switch.

But its actual text is on the other side of it, could take it off and look up the part number and take a look through its datasheet and see if it states something interesting.

Personally, I think it looks a bit small to be fair. Though, the compressor likely don't run much above 1 kW to be fair, so that is likely somewhat sufficient. Or there is a larger device elsewhere that does the actual job of inverting the DC back to three phase AC.

You''ll get it. Alex mentioned they're gonna use a 12th gen Intel proc in a future video. I do hope they're gonna do some Threadripper CPU as well, and perhaps a Ryzen 9 series proc too.

good you didn't have longer hair that day or a hat on, brian the electrician, at the end of 3:59. and safety gl... I mean glasses on

when you see alex and brian become a team against linus and colin. next episode of tech mythbusters! oh...

No matter how much you try to fool the sensors, you won't fool the compressor which will draw liquid any moment there - not having enough thermal load, will make the refrigerant not completely boil inside the vaporizer (CPU block) and you'll get liquid inside the compressor. You won't notice it first, just after you burn out the motor's coils.

What refrigerant did u use ? R134a ?

 

Im guessing it was as its the most commonly used nowadays. That is likely why u couldnt get below -20c. It only boils at -25c. You shoulda tried Propene R1270 which boils at -47c.

So why not dunk the board in oil to beat condensation and water on the block and board?

Great video! One of the more polished "lets try something crazy without much planning" ones.

I mean - I know someone using his homes slab at the heat sink for his Server farm technically.

The compressor is too small. I like at the end of the video they where suggesting building a cascade unit. Yes, do that!  

 

I never gotten into SS or cascade for all the work and energy required to run it, can just get some Dry Ice and actually get some decently cold temps -75c would be no problem even with a home made Dice pot.

 

Cool video though. Brings me back to many years ago when Drewmiester and Sparkey247 where building units locally by me. I got to watch several builds take place.

First off I enjoy watching these videos and appreciate Linus allowing this type of content creation. It is in my opinion the root of "Hacking" and exploration anyone can do.

 

1. Have you thought about using PLC to control the AC system? 

2. I've thought about the condensation issue some regarding OC in general.... What if you placed a wall around the open test bench, sealed to the desk and a couple of inches / Cm above the tallest point of the test bench. Then pour Argon (Ar) into the walled container until it displaces all of the air. Would this no solve the condensation issue? There is most likely a better gas that's heavier but Ar is cheap and safe for experimenting.

@Squashy I have merged your thread into the official video thread. 

[da na]

Sounds like something that I, the man who invented "passive watercooling", would do... 

turns out GT 210 handles 100% OCs quite well when at room temp... 

until it doesn't

Ohh wow, Brian and Alex really work very well together. I watched the Linus + Brian videos too, but I prefer this one.
