Introduce The Refrigeration System Of China Freezer

Update:14 Apr 2021

We can see the existence of china freezer in many foreign merchants, which shows that China freezer is still very practical.

The freezer refrigeration system mainly consists of four parts: compressor, condenser, evaporator, and capillary tube, forming a closed-loop system by itself. The evaporator is installed above the inside of the refrigerator, and other parts 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. Freon 12 is vaporized from a low-pressure liquid into gas in the evaporator, absorbs the heat in the refrigerator, and reduces the temperature in the box. The Freon 12 that has become gaseous is sucked by the compressor, compressed into a high-temperature and high-pressure gas by the compressor, and then discharged into the condenser. In the condenser, the gaseous Freon 12 continuously radiates heat to the surrounding space and gradually liquefies into a liquid. These high-pressure liquids must flow through the capillary tube, throttling and reducing the pressure to slowly flow into the evaporator, and maintain it in the evaporator to continue to vaporize and absorb heat and cool down. In this way, the refrigerator uses electric energy to do work, and with the help of the change in the state of the refrigerant, the heat around the evaporator in the box is transported to the condenser after the box to release it, and it circulates again and again to achieve the purpose of refrigeration.
