Refrigeration reason of freezer refrigerator

The refrigerating room of the freezer lowers the temperature through the refrigeration cycle to keep the food fresh and preserved. In order to realize this process, we need to understand the following important factors:

1. compressor: The key to the refrigeration cycle of the freezer is the compressor, which generates high-pressure and high-temperature gas by compressing refrigerant.

2. Evaporator: The high-pressure and high-temperature gas is cooled by the evaporator and becomes condensed liquid. The condensed liquid absorbs the heat inside the freezer through heat transfer, making the freezer colder.

3. Expansion valve: the liquid refrigerant is decompressed through the expansion valve to reduce the temperature and pressure, and then returns to the compressor to enter the cycle to be compressed and cooled again.

Therefore, the refrigeration principle of freezer refrigeration room is to convert the refrigerant from high-pressure and high-temperature gas into low-pressure and low-temperature liquid by circulating compression refrigeration, and adjust the temperature and pressure through the expansion valve, so that the liquid refrigerant can circulate continuously and absorb the heat in the freezer in the evaporator to achieve the effect of cooling.
