for those 95+ deg days
Nap sounds good. But first I'll explain more Ole Thom. A tube in tube heat
exchanger replaced the air cooled condenser. In this device, hot refrigerant vapor passes through a 5/16" O.D. tube, which has been sealed inside a 7/8" O.D. tube. At both ends of the 7/8" tubing, access fittings were installed to allow fresh water to flow through the 7/8" and outside the 5/16" tubing. In doing so, picks up the heat for removal from the cabin. The refrigerant compressor is the 2nd pump you seek. It moves the refrigerant through the 5/16". It leaves the compressor as a hot vapor and arrives at the expansion device (capillary tube) as a sub-cooled, high pressure liquid. A water pump moves the cool fresh water from the tube-in-tube condenser, through hoses, to the 2nd heat exchanger, which is just a roll of 5/8" O.D. copper tubing, which is dropped into the bay when the AC is used. Otherwise, this 2nd heat exchanger is stored neatly away in a locker (the 22' of 5/8" tubing was shaped to fit in the locker). There is no condenser fan needed, nor is there a need for the old air cooled condensing coil, so I removed them. The indoor fan continues to work in the usual way, drawing warm air through the evaporator where it is cooled and discharged through the louvers.
