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

Abstract

The invention discloses an air-conditioning system, comprising a compressor (1) and an evaporator (2), and further comprising: a refrigeration condenser (3) used for indoor refrigeration and a pump body used for cooling the pump body of the compressor (1) Condenser (4); compressor (1), refrigerating condenser (3) and evaporator (2) form the main circulation circuit for indoor cooling, an opening of refrigerating condenser (3) and evaporator (2) ) is communicated; the outlet of the pump body condenser (4) is communicated with the pump body cooling inlet of the compressor (1), and the inlet of the pump body condenser (4) is communicated with the pump body cooling outlet of the compressor (1), forming a The pump body cooling circulation circuit for cooling the pump body; also includes the control between another opening of the refrigeration condenser (3) and the inlet of the pump body condenser (4) and between the cooling outlet of the pump body and the inlet of the compressor (1) Switching components that are switched on and off at the same time. The air conditioning system provided by the invention improves the cooling and heating performance.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air conditioning system. Background technique [0002] The compressor in the air conditioner works continuously, so that the pump body of the compressor is in a high-temperature and high-pressure environment, and then the compression process of the refrigerant is in an overheated compression environment, and the compression power is high, resulting in a decrease in the performance of the refrigeration system. [0003] In order to improve the performance, the cooling technology of the pump body is usually adopted, that is, by cooling the pump body, the temperature of the wall surface of the working chamber of the pump body is changed, thereby reducing the compression index and achieving the purpose of reducing the compression power. [0004] At present, the usual practice is to divert part of the low-temperature and low-pressure refrigerant to the compressor to ...
