2020-6-18 · BD systems use thin (half-inch), stainless steel cold plates. These direct evaporator plates provide excellent thermal conductivity for cooling efficiency. They're mounted on stand-offs to allow air to flow on both sides. Refrigerators require a single plate which should be mounted as high as possible in your insulated box.

2010-12-15 · Overcharging will increase the head pressure, which increases the flow rate through the expansion device until there is too much flow available for the heat transfer in the evaporator to boil the entire refrigerant off. Result – floodback. Low load is a major problem of most refrigeration systems.

2014-12-5 · The thinking on this is that if a constant cycling evaporator system (like mine) is inadequate to the task then one can move to a holding plate system. The plates themselves can be built with essentially two tubing systems in them, one with coolant driven by the engine when it is on and one by a high powered DC system which can be run while the .

Question: What equipment would be best for my needs? I plan to live aboard in the tropics and my box is smaller than 4 cubic ft, with three inches of good insulation. I also plan to live at anchor away from shore power. ANSWER: In the tropics with two people on board, I would expect your daily requirement to be 2400-3400 Btu. I would recommend a small 1 2-volt DC refrigeration conversion unit .

The air-cooled aftercooler looks very much like a car radiator, and acts like one as well. However, rather than coolant filling the interior tubes, the hot compressed air enters the bottom of the air-cooled aftercooler and tube system, discharging through the upper discharge port into a moisture separator.
