I installed the refrigeration equipment. The second problem found in most marine refrigeration installations is that people install the compressor and evaporator in the engine room, which is the hottest place on board-even when the engine is not running. But the compressor needs cool air as a heat sink, otherwise the chilling process is inefficient and the motor needs to run all the time, using up power and wearing out the moving parts. I solved this by building a plywood housing around the refrigeration equipment and force-venting it with a fan and a deck-mounted mushroom vent.
