hey guys,
been notified of these neck of the woods by marci (on
www.over-clock.com forums) a couple of months ago in an unrelated thread, but i think it's time i registered, and called upon your knowledge.
i`m in the first stages of a DIY phasechange project, and not having used phasechange cooling before i`m a n00b to stuff.
currently have the following kit:
danfoss SC21F compressor (495w)
Aspena T6215Z compressor (790w)
and a tiddly little danfoss rated at 73w.
to come:
condensor
mach 1 head
driers
tubing and valves/connectors etc
in the process of getting some valves so i can connect our aircon machine (r134a) at work upto it and gas it up FOC. 507 MIGHT be done later on.
i must stress this project is just for fun, and mainly for hands on rather than using it as a cooling method for my main rig. performance isnt essential, but 1/2 the reason i`m doing the project. main reason is for hands on and just for the hell of it - hence mach1 head, and not a baker/chilly evap head
1 main question i`m stuck on, and the other is a recommendation:
1 - capilary tube length. this is the main thing i`m stuck on. how do i know (roughly) what length i need as a starting point. i read the length has something todo with gas quantity,gas type, compressor size, condensor performance etc etc so i dont expect a specific figure.
there must be some way of guesstimating the length needed?
as for the recommendation, what should i be looking for in condensor terms?
cooling 790w is not to be taken lightly, so i`ll need a condensor to cool it. question is, how big do i need? size isnt too much of an issue, but obviously an 8foot condensor is a touch OTT.
would a 790w compressor do more damage than good?
i just though that using a 227w pelt on a GPU and you suffer from unwanted freezing and damages the card? would a 790w compressor be a similar situation, and the danfoss 495w be more realistic?
