Phase change project - need advice.

Hello,

I am currently using a phase change CPU cooling system.

My current compressor and condenser is good for about 250 watts.

I am upgrading CPU's to a setup that will require upwards of 500 watts of cooling (possibly more).

I also want to run a 220v-240v compressor for power consumption reasons.

I was thinking about this setup:

Danfoss SC12G
A new 17" x 16" condenser and 12v fan from a BMW e36.

I figure my condenser should be able to shed up to 1500 watts.

This compressor says r143a, but is there a better choice?

Am I on the right track?

Suggestions?

Thanks!

Correction if I may, the compressor is rated for R134a and -35°C evaporating temperature.

Don't forget to keep the compressor in the inlet side of the condenser fan and to pipe up the oil cooling circuit.

What cpu are you going to use that puts out 500w ?
Most peeps when building for 300w+ would be charging with r507 when using in a single stage. It runs at high pressure though, so care needs to be taken.

your thinking is really great and thanks for your post

Will you dump 1500W of heat inside your office? Dont you think a outdoor unit will be better.. at least for summer use?

wow... what a thought, a separate condenser sitting outside, right next to the house AC, just for the computer.

also, 134a is the only refrigerant you can get without an EPA license.
