3. Working principle
The main components of the unit are: compressor, condenser, filter dryer, gas-liquid separator, expansion valve, evaporator, and control instruments and control components.
The working principle is as follows:
Principle of refrigeration: When the refrigeration system is working, the high-temperature and high-pressure refrigerant gas discharged from the compressor enters the condenser and is condensed into a medium-temperature supercooled liquid, which passes through the low-temperature expansion valve. The two-phase mixture of vapor and liquid that becomes low-temperature and low-pressure through throttling and decompression enters the evaporator, evaporates in it and absorbs the heat of the secondary refrigerant flowing through the evaporator, so that the secondary refrigerant flowing through the evaporator can be cooled, and the refrigerant After vaporization, the steam is inhaled by the compressor and circulates continuously to achieve the purpose of cooling.
