Attic Heat Pump
Hello All,
I'm currently working on a new project: ATTIC HEAT PUMP. The idea is to use refrigerant to pump heat from the attic of my home to a water cooled heat exchanger (condenser). It's an exciting concept; however, the endless little installation details make the project tedious!
I am using a 2 ton REFRIGERATION UNIT (R22) salvaged from a walk-in cooler. The EVAPORATOR is in the ATTIC, and the CONDENSER is WATER-COOLED (actually GLYCOL - closed loop).
The GLYCOL LOOP then heats potable water through a second exchanger. I wasn't comfortable running potable water through the used (dirty) condenser.
ATTIC temperatures are presently rising above 100F! Do I need to run the EVAPORATOR FANS at these very high temperatures?
