The refrigerator consists of a cabinet, a refrigeration system, a control system, and accessories. In the refrigeration system, the main components are a compressor, a condenser, an evaporator and a capillary restrictor, which form a closed circulation system. The evaporator is installed above the inside of the refrigerator, and other components are installed on the back of the refrigerator. The system is filled with a substance called "Freon 12 (CF2Cl2, International Symbol R12)" as a refrigerant. R12 is vaporized into a gas by a low-pressure liquid in the evaporator, absorbing heat from the refrigerator to lower the temperature inside the tank. The R12 that has become gaseous is sucked into the compressor, and it is compressed by a compressor to compress it into a high-temperature and high-pressure gas, and then discharged into a condenser. In the condenser, R12 continuously releases heat to the surrounding space and gradually condenses into a liquid. These high-pressure liquids must flow through the capillary tube, and the pressure-reducing pressure can slowly flow into the evaporator, and continue to vaporize in the evaporator, and absorb heat and cool down. In this way, the refrigerator uses electric energy to do work, and by means of the change of the state of the refrigerant R12, the heat around the evaporator in the tank is transferred to the condenser in the tank to be discharged, so that the cycle is repeated continuously to achieve the purpose of refrigeration.
