Guys I'm looking for some info on sizes for and evaporator and condesor for a freon cooling system. There must be some way to calculate how big of a condensor/evaporator you need to balance out the system. Also I need to know where in the system the dryer goes. Is it right on the return line just before the compressor? I've come across lots of great info here on the forums on building freon cooled systems, but no one seems to have assembled one from just old parts. (except scfoster) Any help would be appreciated.

I picked up a 1/4HP Tecumseh oil cooled unit. Its very srong and the guy said it should have no trouble running 24/7 as long as its well ventilated. I was thinking of using a 1/4" copper tubing wound into a 4" diameter coil, about 6" long (about 10' of straight tubing). Is this too much? I will be cooling between 2 and 5 liters of 66:33 water/methanol mixture. The pump flow rate is 230gph at one foot. Should I use a capiliary tube or would a "tx" valve better? (TX valve is sometimes known as a CPE valve keeps the pressure constant going into the evaporator.)

Thanks
