The world's matter has three states: gaseous, solid, and liquid. Under certain conditions, the three states can be transformed into each other.

When the liquid changes from a liquid state to a gaseous state, it absorbs a lot of heat, which is simply referred to as “liquid vaporization endothermâ€, and the refrigerator uses the liquid vaporization heat absorption to cool.
Function of various components of the compressor
The compressor refrigeration system consists of compressors, condensers, drying filters, capillary tubes, evaporators and other components.
The power comes from the compressor, the dry filter is used to filter dirt and dry water, the capillary is used to throttle the pressure drop, and the heat exchanger is the condenser and evaporator.
Circulatory system
• 1. The refrigeration compressor draws in the low-temperature and low-pressure gas refrigerant from the evaporator, and after compression, it becomes a high-temperature and high-pressure superheated vapor and is discharged into the condenser;
• 2. The gas refrigerant in the condenser dissipates heat to the surrounding air to become a high pressure liquid;
• 3. The high-pressure liquid flows into the capillary through the drying filter to reduce the pressure and becomes a low-pressure liquid state;
• 4. The low pressure liquid enters the evaporator to vaporize, absorbing the heat of the surrounding cooled items, and lowering the temperature to the desired value;
• 5. The vaporized gas refrigerant is again sucked by the compressor through the return pipe, and a cycle is completed. The continuous operation of the compressor cold cycle ensures the continuity of the refrigeration process.
