Marine Refrigeration
So how exactly does Marine refrigeration work? The main areas of an Electricity refrigeration system range from the refrigerant, a compressor, along with a condenser, an air conditioning for condenser, along with a plate or plates within the refrigeration box.
The compressor belongs to a shut loop pumping refrigerant with the system and thru the evaporator plate within the ice box. The compressor has two sides our prime side or discharge side. The release side pumps refrigerant pressurized towards the condenser. The suction side or low side and sucks refrigerant after it goes through the evaporator plate to the compressor. The cold plates within the fridge space have either expansion valves or capillary tube that separate the high and low pressure sides from the refrigeration system.
The refrigerant within the compressor starts like a gas. The compressor compresses the refrigerant gas, from low pressure to ruthless between 100-150 psi. Once the pressure is elevated such as this its temperature increases dramatically. This hot ruthless refrigerant will be given to some condenser, where it’s cooled and switched right into a liquid. The condenser is cooled by either air or water. The refrigerant has become an awesome ruthless liquid and it is given for an evaporator plate within the motorboats refrigerator box.
The evaporator plate takes the refrigerant in the condenser and here it boils quickly & evaporates to a gas, in a really low temperature. This transformation of condition absorbs huge amounts of sensible heat in the evaporator which removes heat in the insulated refrigeration box, therefore lowering its temperature. The BTU may be the measurement of warmth removed. In the evaporator plate the refrigerant is came back towards the low side from the compressor, to begin the procedure again.
Evaporator or Holding Plates
Marine refrigeration systems use either an evaporator plate or perhaps a holding plate within the motorboats refrigeration space or freezer space. Each kind of plate works differently in drawing heat in the motorboats refrigerator and ice box space.
Marine Evaporator
Marine evaporator is similar to those present in household refrigerators. They are able to get quite cold (thermostat setting) and lots of evaporators be capable of make ice near the evaporator plate or within the evaporator box. Evaporators are available in several sizes and shapes they may be horizontal plates, vertical plates and folded plates.
Thermostat controlled evaporator temperature. Use lower ice box temperature. Evaporator plates are less costly, but need Constant power.
Marine Holding plates
Marine Refrigerator Holding Plates behave like large blocks of ice and also the winter from the holding plate sucks heat from the motorboats refrigeration box. Holding plates will keep ice boxes cold for lengthy periods.
The primary benefit of a holding plate over an evaporator is they only have to be recharged one or two occasions each day. This charging can coincide with attaching to shore power, running the engine so the refrigerator doesn’t depend around the battery bank. When integrated into a correctly designed system, holdover plates can considerably reduce energy consumption.
