    needmorstuff's Chiller

    This was an interresting build over the last few weeks, alot of experimenting invloved.

    Gary contacted me asking for a chiller to hold 400w at 15c, sounds easy rigth, well its not.

    Firstly I had a Danfoss FR8.5 compressor, it held the load but sounded really really bad. Then I moved on to a Electrolux MP90FB 9cc compressor, a little better but was running quite high pressures, more silent though. Eventually I popped the final compressor in, a R12 1/3hp 12cc Tecumseh. It runs alot better, little noisy when starting for a few seconds but then smoothes out nicely and runs nice and smooth.

    Gary also told me budget is tigth so no fancy cases, controllers etc. I ended up using a Ranco Thermostat and it works perfectly. Current setting holds water temp between 14 and 17c. Capable of sub zero if needed but Gary wants nothing of that No condensation issues or insulating pipes.

    It holds 400w of resistor load easy which in real life is alot more. I believe it can hold 2 or 3 pc's to the current setting.

    Some specs:

    Compressor Tecumseh 1/3hp 12cc
    Evap: Coaxal HX 8' long
    Controller: Ranco O16
    Condensor: From old Ice machine, big though with custom shroud
    Fans: 2 Papst typ9956
    Gas: R22
    Captube: 5 feet 5 inches 0.031
