I've been working for a while on an electric air conditioning system for my RV-10 and thought it might be interesting for some folks.
The basic system consists of a 28V electric compressor (purple), a ~14x20" parallel flow condenser (right), and a ~10x10" evaporator controlled by a TXV (left inside cardboard "evaporator plenum"). The photo above shows the full setup running on the bench for testing. During the test shown, the ambient temperature was 90F and the system produced between 11-12K BTU/hr of cooling. The compressor drew about 34A and the fans 12A at 28V.
Here's a view facing the aft cabin bulkhead. The "final" evaporator inlet is on the left and the outlet to feed the overhead vents is at right.
Inlet side of evaporator box.
Other side and outlet duct. This was my first complex fiberglass part and it shows!
Finally a overhead duct mockup for testing pressure drop and vent location.
