Very nice video. It's really hard to find valuable information on how these things work exactly. I fiddled with them a bit on my own but after seeing this video I can tell, that I did a lot of mistakes. Going to try to fix them now. Thank you.
Hope it helps! There is a lot of ways to configure a system like this but hopefully the simple phase change setup is a good starting point for you. It works well for cheap, but definitely people make a bunch of other really neat and functional systems too!
So... one thing I'm still unsure of, is how do you choose the pressure you add to your liquid pipes? Also why did you specifically set the pressure regulator you used to dump pollutant into the coolant loop to 250 kpa? Was there a reason or did you just randomly hit pressure-up a couple times because you just need 'some' input?
For your liquid pipes, you want enough pressure in the liquid pipe that any of your coolant gas stays a liquid when it gets pushed to your liquid pipe. If there isnt enough pressure, any condensed liquids from your condensation chamber will evaporate in your liquid pipes to get that pressure, if you were working at low temperatures, this could run the risk of freezing the coolant in your liquid pipes so as a safe measure you would want to pressurize the liquid pipes. As for adding coolant to the gas pipe, the number I chose was an arbitrary pressure. You dont want to overfill the chambers so pick a low enough pump rate on a volume pump or pressure regulator. You want to be watching the condensation chamber to see when condensation begins happening and then watch the evaporation chamber to see when it will reach the target pressure inside it. A slower pump rate is easier to react to because overfilling the system with a coolant brings a risk of rupturing pipes if one of the chambers stops working or if one side's temperature goes out of whack.
@@shadowdrake082 Alright.. and it's okay to use the same gas to pressurize the pipe, like I think I saw you just put pollutant in the liquid pipe to pressurize the liquid pipe right? You don't need to mix nitrogen in or something like that? I think that's right. I don't know why but the gasses just confuse the everloving hecc out of me, I don't know why they changed so much about it to make it such a friggin' headache!
@@KittenyKat For starting out, I would recommend pressurizing with the coolant gas. This is because as a safety measure, the coolant in the liquid pipes can evaporate or condense as needed when you have temperature and amount of liquid fluctuations. When you start getting ready to fine tune the system and get whatever little extra efficiency out of it as possible, then I would recommend pressurizing with a different gas that wont condense at those temperatures and pressures. But it does mean you would need to consider cases where the liquid temperature gets high or if the liquid pipe network fills up with liquid and then have to factor safety measures for overpressurization.
11:00 damn those powred vent are no joke i remember having an array of passive/active vent trying to fill some tank and here it take mere second to fill a tank lol
They really are. Got to be careful with them though, they dont really have safeties... it says they do but I still tend to explode my pipes if I leave them unattended or way overpressurize a room.
@@shadowdrake082 yeah they dont have pipe protection but should have room pressure protection based on the logic input it has the (PressureExternal) but missing PressureInternal
Not to my knowledge, they seem to work the same then compared to now. Just so long as you dont confuse it with the original heat exchanger and make sure you build the correct counterflow for what you need. Is there something weird you are seeing with yours?
Well it does depend. I think the context I was going for is that if you want to use a condensation chamber to heat, the evaporation chamber needs to be set low so that it can grab as much thermal energy as possible to go towards the heating in the condensation chamber. If you just want to cool to the lowest a coolant can occur, you can set that to be almost 0kpa and it will keep doing the cooling to the freezing point of the coolant gas.
I understood why you pressurized the liquid pipes because you want to keep the liquid from evaporating. You lost me when you pressurized the gas pipes. Why was a regulator needed here? Is it just to prevent condensation of the coolant from too much pressure?
That was how i filled the system. Once the whole system was filled to the desired amount, the pressure regulator can be shut off and removed. At the time i also didnt want to push too much too fast so that i didnt overfill the system or pressurize the gas pipes too much to cause condensation and potentially break the pipes.
Well put together video. Very helpful information. Vocal audio was a bit low. I'm still trying to wrap my head around the phase change update. I can't even collect gasses without having pipes stress out on me and burst or freeze then burst. Do you have a gas collection setup that works fairly well without having pipe destruction issues?
I did make a phase change mechanics video, hopefully that can help a bit. In short, phase changes happen due to low temps and/or high Pressures. It would require reading the phase change diagram of the gases and understanding the information provided to help with how you will want to store it. But if you store gases in regular tanks, you need to be watchful about the effects of heat gain/loss depending on the world you are in. First thing I can recommend is to make sure you have plenty of silicon and steel to make insulated pipes and tanks. The better you can control the temperature of your gases the less likely you will have phase change related issues.
I'll try to see if I can help, but without seeing the setup I may not be able to tell for sure which of these will work. If evaporation is happening in the liquid pipe, then: 1) Not enough pressure in the liquid pipe network yet, it will keep evaporating until there is enough pressure to contain the liquid at the given temp. 2) The temp in the liquid pipe exceeds the coolant's max condensation temperature. If you have a counterflow heat exchanger between the condensation chamber and evaporation chamber, then another possibility is that the evaporation chamber is trying to cool something extremely hot so that the evaporated gases are hot and warm up the liquid to the point of evaporation.

This was really well done! thank you for putting that together

This is just what I need. I salute you good sir!
Awesome job breaking it down
Hope it helps and or starts you off! Best of luck!
@@shadowdrake082 got 1500 hrs in the game and still learning. Going back through you other videos now. Thanks and same to you

Did the counterflow heat exchanger change? Seemed so simple 7 months ago, when I try it the whole thing goes kerfullie in a hurry

Only question I have is, why when on a cooling set up, you want to set the pressure as low as possible on the evaporation chamber?

Doesnt work, liquid evaporates on the liquid pipe no matter what pressure you presurise it to.

If evaporation is happening in the liquid pipe, then:
1) Not enough pressure in the liquid pipe network yet, it will keep evaporating until there is enough pressure to contain the liquid at the given temp.
