I have a Iso-Therm SP system with a Danfoss 50F
compressor. The condenser is the SP type, which is has a tubing wrapped in a coil inside a thru-hull. The motion of the
boat causes the seawater in the thru-hull to transfer the heat from the condenser tubing.
I have two boxes side-by-side for
refrigeration in the galley--one is a top loader, the
freezer, and the other a front loading
refrigerator. Up to now, they system has been adequate: the
freezer freezes things solid and the
refrigerator hovers between 38-42F.
My problem: the freezer still keeps things frozen, but the refrigerator is in the upper 50's. As near as I can tell, I do not have a spill-over system whereby there is an opening between the freezer and the refrigerator for the colder air to circulate from the freezer to the refrigerator. Is it possible for one
compressor to have two evaporators with a Y-valve in between? How does one compressor with (as far as I know) one evaporator do two boxes that are not connected by an opening to transfer the cold air?
Some might suspect low refrigerant, but on adding some, the compressor runs hot, as in real hot.
