Refrigeration system of freezer & cooler
Refrigerator refrigeration system mainly consists of compressor, condenser, evaporator and capillary four parts, from itself into a closed circulatory system. The evaporator is arranged above the inner part of the refrigerator, and other parts are arranged on the back of the refrigerator. The system of filling a called "Freon 12 (CF2Cl2, international symbol R12)" substance as refrigerant. Freon 12 in the evaporator by low pressure liquid vaporization of the gas absorption refrigerator, heat, the temperature decreases. A gas Freon 12 compressor suction, by compressor compresses it into high temperature and high pressure gas, and then discharged into the condenser. Freon gaseous in condenser in the space around the 12 continue to heat, gradually form liquefied liquid. These high-pressure liquid must flow through the capillary tube, throttling, reducing pressure can slowly flow into the evaporator, and maintain in the evaporator continue to vaporize, endothermic cooling. In this way, the use of electric refrigerator can do work, with the change of refrigerant to the evaporator in the state, the surrounding heat transported to the condenser to the box after the release, so the cycle continuously, in order to achieve the purpose of refrigeration.
