In my highschool shop class, a classmate was working on some older Japanese car, putting either the head gasket or valve cover back on and over torqued the bolt which broke off, recessed inside the engine block. I was right there and noticed it was prolly fucked and needed to get drilled out. Our teacher came over, and agreed, yup, its gonna be the hard way, and informed us the car was actually one of his personal cars, and he'll deal with it from here. He gets it out, calls us and few other students over and begins to explain to us what a tap and die is, what its used for, yada yada. So he begins his cruel journey and about halfway done, the tap broke damn near flush with the engine block. He stood up, stared at it for a good 3-5 seconds and chucked it across the shop floor, directly hitting his computer monitor on his desk, sending it to the floor. The "are you fucking kidding me" he let out was beyond epic and saddening at the same time, like a lone wolf howl. thus it became an inside joke among me and one of the classmates im still in touch with, and when i have some bs happen, ill mimic it nearly 10 years later. I have my tap and die set label with anger and sorrow because of that. Thankfully I've never had to use it.. yet.

Another HVAC tech here: Both the outdoor & indoor units have multiple sensors to measure the superheat and subcooling in real time in order to adjust the Thermal Expansion Valve (TXV) and the inverter that controls the compressor speed, to ensure proper cooling of the compressor by the returning refrigerant. Also, you need a substantial, uninterrupted *heat load* from the CPU to keep the whole set-up running, without which returning liquid refrigerant may kill the compressor or simply just cause it to stop(depends on how sophisticated it is). Either way this is not a long term/viable solution as something will definitely break in the short-medium term. Also, that a/c is way too large (capacity) for such a small heat load.

@chaoseclipse0121

Жыл бұрын

Fully agree with the last part, the mini-split was way too much for the heat load they were throwing on it (Guessing that was a half-ton split from the size of it). Would've been better if they butchered one of those mobile HVAC units with the plastic heat exhaust tube for windows, especially since the compressor inside those things are usually DC Voltage and you'd only need to use a power converter to run it (And even the ones that are AC Voltage, you'd only need single phase power), and possibly even use a contactor to allow the PSU to engage the compressor only when the PC runs...presuming you could find a 12VDC PTE contactor. Something else they could do to ensure they're not sending liquid refrigerant back to the compressor would be to have a secondary thermal exchanger / evap coil after the CPU cooling block to ensure they fully evaporate the coolant before it reaches the compressor, or possibly have another thermal exchanger to a liquid loop to provide chilled water cooling to the GPU and RAM.

Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) kzread.infoUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.

Good call from Brian on making a (bit of an) orifice on the copper tube end. That tube opening was quite large, leading to an inefficient throttling. You want a very small opening (relatively) for a good Joule-Thompson (adiabatic expansion of gas) effect. Also, a tip: put the motherboard in a big box en put either dry ice or a container of liquid nitrogen in there. The sublimated/evaporated gas will push out any 'normal' air and keep most of the moisture out. And finally: CPU temp sensors typically can't report negative numbers, so will just say 0.

Hey LTT! hvac tech here. The mini split you're using (as most of them are) is "inverter driven", which means the computer inside varies the speed of the compressor based on various sensor inputs. Even if you trick it into coming on, that doesn't mean it will run at full power. It could run at as little as 10% capacity in some cases. It would be much easier to control and much more consistent if you replaced the 3 phase compressor with a single phase one, you could find in a window unit. You could just flip it on with a heavy duty light switch. Easiest solution is probably to take a working window unit, and steal the refrigerant lines going to the evap coil for your heat sink.

He obviously knows nothing about HVAC yet he owns a 4 port Brute manifold??? A half assed metering device at best in a half assed evaporator and ridiculous slugging potential. The only thing that saved that compressor from blowing the valves into a million pieces is the massive accumulator in the condenser (that was bypassing 99.999% of the air, thus rejecting little to no heat). A tiny window shaker would have been more than sufficient BUT you actually lose capacity when you fail to boil all of the refrigerant leaving the evaporator into vapor. Because of MASSIVE dynamic load changes the refrigerant MUST be metered with a TXV or EEV (if not multiples manifolded together to make some level of half assed load shedding), hands down, no way around it. What they rigged up would never last 7 days in continuous operation. I need to stop clicking on random videos that have morons playing with refrigerant.

They did in 1999. The product line lasted for a few years but ultimately remained too niche and too expensive.

By the way. Next time you try this if ever you should try a small plate exchanger. So refrigerant in and out one side of the plate then water pumped through and into a standard CPU cooler. Would be much easier to deal with. Essentially a small chiller system

"I'm legally required to say no, I think." Next time on Inside LTT: "Send it."

3 things... 1). Think about removing some refrigerant from your mini split, you have much less capacity on your heat sink, if you are frosting up your A/c unit, you may restrict refrigerant flow ( I've seen this on an overfilled A/C unit) 2). Two-staging a heat exchanger is super effective, I think Applied Science did one a few years back on his channel. 3). Invert you motherboard, let gravity work for you and let the eater drip away from the Motherboard. You are still thinking that you are pouring coolant into a reservoir on top of the heat sink...you don't have to do that now.

Alex is made for this stuff, it's even better when there's no linus rushing and breaking stuff.

As other comments have pointed out, i'm not convinced that evaporator block is actually causing all the refrigerant to evaporate and there is lost potential to get even better cooling performance. I'm also pretty sure that when the CPU is off/idle, there is less energy to facilitate the phase change, a lot of the refrigerant remains a liquid. The low pressure line (blue I think) shouldn't have frost on it, as this suggests to me liquid is going back to the compressor (backed up by the compressor getting all frosted). Liquid going into compressor = bad. Maybe try a larger volume/more heat fins for the CPU block? Somebody else suggested an expansion valve instead of an orifice which might help.

I like how the thumbnail shows the exhaust blowing the cpu.

You should consider putting the mini split evaporator inline after the cpu block but without its txv to avoid sending liquid to the compressor. With a heat load being so small you might still grenade your compressor. If you put the evaporator back inline you’ll still be able to maintain -20c because that’s the temp your refrigerant can change phase at 40psi assuming it’s a 410a unit. Then the evaporator can fix the heat load issue and you won’t need to trick the sensors. Also you could direct the evaporators fan at the pc to help remove some humidity in the air and cool the rest of the pc.

Agreed, with everything you said. I would imagine this unit is also over-pressurizing and tripping the safeties to protect the compressor. If they really wanted to control the system well, they could drop the evap coil in a bucket of water with a circulator and some propylene glycol (maybe even a small heater) to artificially load the AC unit and keep it from tripping, and keep the AC unit running for as long as they need.

A mini split was probably the worst type of AC unit to do this with lol, they have an incredible amount of sensors and safeties integral to the system. Im actually surprised you guys got it to run at all. A small window unit may be a better choice, much less going on internally. Also, you may consider simply running the cooling block in line with the evap coil, after the metering device and before the coil, although this may not reach the temps you guys would like. Perhaps a fix to that may be to restrict the airflow through the coil, either by disabling the fan, or blocking most of the coil. Also note that the compressor will suffer damage from all of this, and the head pressure may jump to extreme levels- worst case scenario it ruptures a line, especially if the high pressure safety is bypassed. If it does, evacuate the room and ventilate it, as refrigerant displaces oxygen. -HVAC Tech

Worked with these AC units for a couple years but mostly did the refrigerating in grocery stores. When the compressor suction line is getting frosted it means that gas did not return to liquid yet basically and the "black thing" next to the compressor is a filter to catch that liquid to an extent. (Compressors do not like liquid and the valve plate inside will bend from it rather quickly) To go a little more in depth the liquid gets sprayed in the evaporator block and this will be 100% liquid vapor and when the warmer air gets pulled through the evaporator with the right settings it should return to gas form ideally 0% liquid vapor. Usually this is controlled by an automatic valve in AC and in grocery stores or bigger applications its a valve that shoots controllable burst of liquid vapor to control both temp and to ensure that the refrigerant returns to Gas. If this project ever gets a sequel or for any DIYers out there "Danfoss" makes both the valve and programmable regulators for it. Split units and their circuit boards are so complicated that any AC mechanic calls the supplier when something is wrong other then an easy to fix code. While it can literally be compressor with a simple pressure regulator that turns the compressor off before it reaches vacuum and set to turn on when it reaches a certain amount above the pressure set for shutting it off on low pressure. The pressure regulator compressor control technique is not even that getto, its used a lot for businesses that need refrigeration on a small scale like a bakeries for example. Ac's are made to not be fixed and are overly complicated. Hope this info is still useful on an old video. ^^

That looked like a lot of work. I think a more practical setup is to cool the coolant vs direct cool... take that frosty line and wrap it like a spring around the CPU coolant reservoir. I've thought about doing that in the past, just haven't gotten around to it yet.

@Turtle1631991

Жыл бұрын

You could just replace radiator with heat exchanger (acting ad the condenser at the same time) between coolant and PC cooling liquid (you can 3d print copper these days). That would also allow you to cool both GPU and CPU easier (unless you want to pass the coolant through GPU before sending it to compressor or make double condenser setup). You could set up temperature sensor at the intake side of the exchanger to have to cooling system go on and off based on liquid temperature. Also bigger reservoir so that doesn't happen every minute. For more practical solution I would scavenge system from a fridge. Those are simpler and easier to service. and oftentimes are literally just controlled by single thermostat. alternatively if one really wanted direct cool, It would seal the case as airtight as I can (maybe with some small pressure equalizing hole) and set up some kind of silica gel dehydrator (possibly with some really slow noiseless fan to make it more effective) That would take care of water condensation

This is exactly what I have been wanting to do for fifteen years --- a phase-change sub-ambient cooling system. But my plan involves using either a mini-fridge compressor or one of the really cool tiny compressors from Aspen, and cooling a liquid loop via an evaporative coil-to-water block interface so that multiple components can be cooled, and also to eliminate condensation on the components themselves. In addition, a fail-safe bypass liquid circuit is necessary so that the coolant can flow through a standard radiator if the refrigeration fails. I live in a desert with a very low relative humidity, so I believe I can get the liquid temperature significantly below ambient without any condensation problems.

Too late

There's a super easy way to prevent the whole condensation issue with subzero cooling, just put the PC in an airtight enclosure. The volume of air in the enclosure won't contain anywhere near enough water vapor to cause problems, even if it condenses at a single point (you can do the math with the humidity and volume of air to see for yourself). You get condensation issues because you're exposing the cold elements to the entirety of the air in the room (plus more due to the room's ventilation), which does contain a significant amount of vaporized water. Using an airtight enclosure would allow you to bypass the standard sub-zero condensation mitigation practices that essentially ruin the PC components (vaseline etc.). This is not hard to achieve. While I have you here, to prevent algal formation in water-cooling loops (the gunk that you have to clean out of the loops periodically) simply boil the water for ~20 minutes before adding to the loop. This is not to sanitize the water. This is to degas the water, meaning there no dissolved CO2 for any biological contaminants to feed on.

Hi, mechanical engineer here, active in the field of HVAC&R, from residential stuff to big industrial/commercial. I would prefer a simpler on/off unit ( not a frequency inverter one ) mainly because i wouldn't need to reverse engineer the controller. I would just use a simple digital thermostat and a relay to power the compressor. Also, some of those have an electronically controlled expansion valve, PITA for your use case. I would try to design the evaporator as an assembly tightened with fasteners and flanges. We use a lot valves and filters in the field that are made similarly. And I would try to put a cavity for the probe of the digital thermostat. Did Bryan use an oxy-acetylene torch, or an acetylene only? An oxy--acetylene kit would be better for this one ( hotter flame, faster heating, faster brazing ). You evacuate the circuit, first of all because humidity can plug the expansion orifice ( capillary tube, orifice, or expansion valve ). Secondary, some refrigerants can form acids if there is humidity in the circuit , and this causes premature wear in the components. Thirdly, because with flammable refrigerants there is a possibility for explosion ( air and fuel under pressure, is what makes diesel engines go brrr ) The compressor in the unit is probably three-phase. I haven't seen a vfd driven unit with a single phase AC current compressor. Though, it might be higher voltage than the one provided in Canada, in order to use smaller cross section of cables for a given amperage, and ( if I am not wrong) better efficiency.

Thank you LTT for providing me with interesting content :) Edit: After watching the video i would love to see you use a proper expansion valve in the follow up video. It makes controlling temperatures and condensation much easier. It would also probably bypass most of the issues you are facing with controlling the hvac unit, since it's set up to be used with an evaporator that uses an EV. Due to the CPU thermal load characteristics an EEV (Electronic Expansion Valve) is probably a good option.

I greatly appreciate this type of content. More tinkering please!

When I did ammonia refrigeration for a poultry factory we used plate heat exchangers almost in every department with glycol. Very efficient till they have to be split and cleaned haha.

The comment about using the aircon to cool the cryocooler is actually pretty sensible. I used to work, many years ago, for a company that made and distributed heavy-duty cryo freezers for laboratory use, and at the extreme, they used up to four stages. This is for the type of labs that deal in class 4 pathogens, so each system of multi-stage compressors and refrigerants is dualled with a parallel one running from a completely independent power source with ultimate fallback to liquid nitrogen. Total redundancy there, but which thankfully, you don't need. If you think you know who we were supplying you may well be right, but I can't confirm or deny it. Those freezers are extremely bulky, extremely heavy, and eye-wateringly expensive! Less extreme ones though (2 or 3 loops, no redundancy) weren't nearly as bad in price or unwieldiness. The difficulty outside that very specialised industry is in obtaining suitable refrigerants, as each stage needs to operate within a different temperature range. The readily available ones just don't go as cold as you might want - they stop evaporating and go back to the compressor as liquid, with predictable and messy results., so as you get in from the outer loop towards the inner one(s) you need refrigerants which have lower and lower boiling points. And each stage needs to be thermally insulated inside the one outside it. I'm afraid that as a lowly entry-level into that company I do not know what compounds were used as inner loop refrigerants, and it may have changed since then anyway - this was back in the late '70s. The best way to avoid condensation and frosting is to run it in an anhydrous atmosphere - totally remove the humidity - and luckily the outer loop of refrigeration is rather good at doing that. Be careful of static in a completely dry (as in below 5% humidity) environment though. Normally, the water in the air gives a nice slow leak-down of static, but dry air doesn't do that. So grounded wrist straps all round, or one fingerpoken will cause spitzensparken mit puffensmoke und blitzkaput 😞.
