The cold storage refrigeration system includes 4 main parts: compressor, condenser, expansion valve (throttle valve), and evaporator. The entire refrigeration system of the cold storage is connected by a circulating pipeline to form a closed circuit. Refrigerant is charged in the pipeline. The compressor plays the role of compressing and transporting the refrigerant gas in the refrigeration system of the cold storage, that is, the low-pressure and low-temperature gas generated in the evaporator is sucked back, compressed again into high-temperature and high-pressure gas and sent to the condenser. www.yanghuzl.com (Changzhou Yanghu Refrigeration specializes in the production of polyurethane cold storage panels). The expansion valve is installed between the liquid receiver and the evaporator, and is a part of the high-pressure area and the low-pressure area in the system.

The expansion valve is installed between the liquid receiver and the evaporator. It is a dividing point between the high-pressure area and the low-pressure area in the system. Its function is to throttle and expand the high-pressure liquid and turn it into a low-pressure liquid. It also regulates and controls the refrigerant flow. level. The condenser is used to cool and condense the high temperature and high pressure gas pressed by the compressor, and liquefy the high temperature and high pressure gas into a normal temperature and high pressure liquid under a certain pressure and temperature. In the evaporator, the low-pressure refrigerant after throttling and expansion absorbs heat from the warehouse and evaporates into gas, which reduces the temperature of the warehouse and achieves the purpose of refrigeration. The compressor plays the role of the heart in the entire refrigeration system and is the process of providing energy compensation. The condenser and the evaporator are two heat exchangers, the former makes the gas of the high-pressure refrigerant release heat and convert it into a liquid; the latter makes the liquid of the low-pressure refrigerant absorb heat and turn it into a gas. Refrigerant becomes the carrier of heat energy in the process of reciprocating cycle. The cold storage board of www.yanghuzl.com has two parts: high pressure area and low pressure area in the whole refrigeration system. The working section from the discharge end of the compressor to the front of the expansion valve is the high pressure area; The working section is a low pressure area; the pressure of these two parts is approximately represented by the exhaust pressure gauge and the suction pressure gauge respectively.
