HOWEVER the U570 ( a Type VIIC )capture report states that they had............
"A small refrigerator, combined with little stowage for food and a small galley, "
From U-Historia..... In the submersible, a refrigeration plant is installed for food preservation and ice production. It consists of a refrigeration unit, located in the control room, and a refrigeration chamber in the NCO room. The cooling unit consists of a compressor with its drive motor and condenser. The refrigeration chamber houses the evaporator. The cooling is achieved by collecting external heat by means of a coolant (freon), which thus vaporizes. The process is maintained, when the freon vapor is extracted, pressurized by the compressor, and condensed to liquid. The side of the evaporator of the compressor, provides the low pressure required to evaporate the refrigerant, while the side of the condenser, provides the high pressure necessary for the condensation of the vapor. The movements of coolant, from the condenser to the evaporator, circulate through a regulating valve. The valve maintains the constant flow of refrigerant and despite its double state changes, it does not allow it to vary anywhere in the refrigeration circuit. The compressor is an air cooler, 1 stage, 2-cylinder, piston and vertical design type. Both cylinders and cylinder heads are presented as a block, which is screwed to the crankcase. The compressor is driven by a shunt DC motor with auxiliary series winding. The motor cover is protected against splashing water, and is resistant to humidity and to the inclination of the submersible up to 30 |
