The working principle of the utility model is as follows:
the refrigeration compressor 1 compresses cold refrigerant vapor into a high-temperature high-pressure gaseous refrigerant. Due to compression, the high temperature heat of the refrigerant will be carried away by the atmosphere (air cooled condenser) or by the water (water cooled condenser). The high-temperature refrigerant flows into the condenser 3, where it is cooled and condensed or liquefied. The liquid refrigerant then flows through the oil separator 2 into the receiver tank 4, from the receiver tank 4 through a filter drier (filter) to the expansion valve. The oil separator 2 functions to separate the refrigerant from the lubricating oil. The function of the receiver 4 is to ensure that there is liquid refrigerant for expansion. The filter drier (filter) filters the refrigerant, and the expansion valve reduces the refrigerant pressure. The cold liquid refrigerant flows into a heat exchanger (evaporator) where it cools (condenses) the gas and evaporates to a cold vapor. The evaporated (cold) refrigerant flows into the gas-liquid separator 7 through the suction filter, and the separated gaseous refrigerant flows into the intake port of the refrigeration compressor 1. The function of the gas-liquid separator 7 is to store liquid and to transfer gaseous refrigerant. The suction filter prevents external particles from entering the refrigeration compressor. When entering into the defrosting stage, the high-temperature and high-pressure gaseous refrigerant flows into a heat exchanger (evaporator) E-201A (E-201B) from the A (or B) end after the electromagnetic valve 9 (or 10) is opened, is cooled and condensed or liquefied, and then flows into the liquid storage tank 4 from the port C to enter the system circulation.
The working process of the utility model is as follows:
when the low-temperature low-pressure gaseous refrigerant flows into the refrigeration compressor 1 from the second filter 6 and the gas-liquid separator 7, the cold refrigerant vapor is compressed into the high-temperature high-pressure gaseous refrigerant by the refrigeration compressor 1 and then flows into the oil separator 2, enters the air-cooled condenser (or the water-cooled condenser) 3 through the first electromagnetic valve 8 to be condensed, liquid flows into the liquid storage tank 4, enters the second electromagnetic valve 11 (or the third electromagnetic valve 12) and the first expansion valve 15 (or the second expansion valve 16) through the first filter 5, enters the heat exchanger (evaporator) E-201A (E-201B) after being expanded, decompressed and cooled by the first expansion valve 15 (or the second expansion valve 16), exchanges heat with high-temperature gas, is returned to the air inlet of the refrigeration compressor 1 through the second filter 6 and the gas-liquid separator 7 via the sixth solenoid valve 13 (or the seventh solenoid valve 14), thus circulating. When the heat exchanger (evaporator) E-201A (E-201B) needs defrosting, the first electromagnetic valve 8 is closed, the second electromagnetic valve 9 (or the third electromagnetic valve 10) is opened, the sixth electromagnetic valve 13 (or the seventh electromagnetic valve 14) is closed, the first electromagnetic valve 8 is opened after defrosting is finished, the second electromagnetic valve 9 (or the third electromagnetic valve 10) is closed, and the sixth electromagnetic valve 13 (or the seventh electromagnetic valve 14) is opened intermittently for 10 times, and the cycle is repeated.
