how air conditioner works exactly

acording to this {LINK REMOVED}https://ctrlv.cz/W5dY
it didnt changed temp to 20c ive put in the in/out tubes that it sucks out and puts into room but the room temp stays in night at -72 at day at 40c +- and it doesnt move an inch :/ its broken i think

What do you have the waste pipe filled with?

I filled mine with ~1MPa of cold CO2, because I was initially trying to remove heat, and hooked it up to 4 medium radiators. Now, with a proper gas filtration setup and the room moderating my water temp, I try to keep the waste pipe around 20C.

If I was doing it over again, I could easily get by with less radiators.
And depending on the exact situation it would likely be beneficial to have it hooked up to its own 5kw circuit, if you don't want to run heavy cable.

i need room filled with CO2 for plants , waste and input pipe are hooked together to passive vent so it sucks CO2 from room and outputs it again but as it goes i think that doesnt work anymore ?

Trying doing something to regulate the flow of gases. This could be as simple as adding more pipes or using one of the various devices that do that sort of thing.

Basically what I think is happening is it is letting to much gas flow through it to quickly to allow for it to actually cool down.

[h_LordEC[no-VC]]

Yeah, I don't think it can work that way anymore since the Aug '22 update.
I believe that is when they made the A/C unit work somewhat similar to a real A/C unit.
The waste pipe equals the opposite of whatever comes out the A/C's output pipe, so running it with the waste/input hooked together causes a neutral exchange in the room.

I could be wrong though since I haven't personally experimented with all the possible A/C setups.

Also, disregard the 5kw circuit comment I made. Rewatching a Cows are Evil youtube video, it appears the "new" A/C unit only pulls about 355w max.

The AC unit works as a controlled heat exchanger in that it will sink or pull heat from the waste line gas to maintain a desired temperature on the output line by heating or cooling the input line. Typically, when inputting and outputting gas from the same room you can get away with linking the input and output together. The waste line should always remain independent as it is this line which you are either taking heat from or disposing of heat to in order to maintain the desired temperature in your room.

Note that the AC efficiency will drop when your waste line temperature is hotter than your room temperature when trying to cool your room (i.e. transfer heat to the waste line), and vice versa when your waste line is colder than your room when attempting heat your room (i.e. transfer heat from the waste line). Edit: So when cooling your room it is preferable to have the waste line gas be colder than the desired room temperature, and when heating your room having the waste line gas be warmer than the desired room temperature.

Cheers!

so summary : If waste is hotter than in room temp i can heat with that but not cool but if the waste is cooler i can cool with it but not heat correct ?

Not exactly... You can still cool with a hot waste line and still heat with a cold waste line, it's just that the air conditioner will operate at a lower efficiency in such conditions. And the greater the disparity in these adverse conditions the more the operating efficiency drops.

If you hover your mouse over the upper left side (front) of the AC units, it will provide efficiency numbers and should indicate the problem.

There is an allowed temperature differencia. Example - you want to cool your room to 20, and have atmo of 80-100c. You put input in the room, aswell as output, but waste goes to passive pump outside. It will still be cooling by exchanging room excess temp to heat waste above 100, but somewhat ineffective, and if atmos say 463 (Venus) you wont be able to cool at all (until you chain ACs specific way to cool each other's waste).

yes if i hook AC in specific way but will that work on Vulcan too ? XD i kinda hoped it doesnt get so hot but 672 c is cookin

No it's way too hot. You can either collect night "cold" 127 air and cool it again at night only to use as temp accumulator, or use series of ACs, check youtube there a few good examples of required setup.

[Hotblack Desiato 42]

On hot planets, e.g. Venus and Vulcan, it was more prudent to pursue acquiring winterspawns and establishing a garden to create cold atmo for cooling, of course that involves trading.
