probaly really noob questions you guys havent heard in a while

good afternoon, im sorry if im going to ask questions that have been asked before but i tried searching the threads and am still a littly iffy.

I have been researching to converting a unit into a liquid chiller... so my first question is...

Would it be easier to convert an a/c unit to a liquid chiller or a mini fridge unit? (i learned a great deal reading through the 'chiller/ac unit' thread", so that is probaly easier, i just wanna know the cons to converting a mini fridge bc.. i have a spare one, its a haier 1.7 model bc-50, compressor is an LG nsa24lacg which displaces 2.4cm^3[dunno what that means but im sure u do])

What is high side vrs lowside?

Also if i used just 2 waterblocks in my loop for the cpu/gpu, what would be the optimum amount of liquid that one should use. basically when does it normally become an 'excess' of coolant for a chiller??

can someone explain casading/auto cascading??


try to not be harsh yo's.
thanks for your time

Ok real quick:

Use an AC unit; a minifridge cannot run long/hard enough to play with the big boys.

High side part of the refrigeration system that operates under high pressure; it begins at the discharge of the compressor and ends at the evap. The low side is the part that operates in low pressure, it begins at the evap and ends at the suction of the compressor.

The only bearing the amount of coolant has on performance is the "momentum" that the system has. Ie, a system with a large amount of liquid will take a long time to pull down to operating temperatures, but this will allow you to cycle the compressor. Systems will little fluid cannot cycle but has almost no pull down time.

A cascade is a system in which a compressor (in stead of a condenser) is used to chill the high side of a second compressor. This allows for the second compressor to use a refrigerant with a much lower boiling point, and thus achieve lower temps.

I hope that helps.
