Air conditioning system

Abstract

The invention discloses an air conditioning system. The air conditioning system comprises a compressor (1) and an evaporator (2) and further comprises a refrigerating condenser (3) for indoor refrigeration and a pump body condenser (4) which is used for cooling a pump body of the compressor (1); the compressor (1), the refrigerating condenser (3) and the evaporator (2) form a main circulation loop for indoor cooling; one opening of the refrigerating condenser (3) is communicated with the evaporator (2); the outlet of the pump body condenser (4) is communicated with a pump body cooling inlet of the compressor (1) and the inlet of the pump body condenser (4) is communicated with a pump body cooling outlet of the compressor (1) to form a pump body cooling circulation loop for cooling the pump body; the system further comprises a switching module used for controlling simultaneous connections and disconnections between the other opening of the refrigerating condenser (3) and the inlet of the pump body condenser (4) and between the pump body cooling outlet and the inlet of the compressor (1). Through adoption of the air conditioning system disclosed by the invention, the refrigerating and heating performances are improved.

Description

Technical field [0001] The present invention involves the field of refrigeration equipment technology and specially involves an air -conditioning system. Background technique [0002] The continuous work of the compressor in the air conditioner makes the pump of the compressor in a high -temperature and high -pressure environment, and then the compression process of the refrigerant is in the overheating compressed environment, the compression power is high, resulting in a reduction in the performance of the refrigeration system. [0003] In order to improve performance, the pump cooling technology is usually used, that is, by cooling the pump body, changing the temperature of the pump body wall surface, thereby reducing the compression index and reducing compression power. [0004] At present, the usual method is to divert some low -temperature and low -pressure refrigerant to the cooling pump body in the compressor, and then mixes the refrigerant that absorbs the heat of the pum...

AI Technical Summary

Problems solved by technology

[0005] However, directly using the low-temperature liquid refrigerant in the refrigeration system to cool the pump body does not improve the performance of the compressor very well.

Because of the refrigerant split operation for cooling the pump body, the flow of refrigerant entering the evaporator is reduced, thereby reducing the cooling capacity, and the refrigerant that absorbs heat flows back to the compressor, and the heat of the pump body still exists in the refrigeration system. affect cooling performance

It is also possible to dissipate heat from the compressor alone, but in the heating state, the heat generated by the pump body cannot be used, which affects the heating performance of the system
