I understand that..... the evaporator is pulling in the warm, humid air and cooling it so the moisture condenses and cools. There must be a drain for a drip pan for the evaporator that exits the unit on the roof. I didn't see anything while insulating the metal box around the evaporator so I assumed the condensation was from the metal being cool and condensing the humid air on the roof.
I remember that one of my home A/C units was rated extra quiet and it was because they placed an insulated bag around the compressor to quiet the noise. I just started wondering if there was more efficiency to be had by insulating the compressor on the roof to minimize a loss in cooling around the compressor.
