Abstract

The invention provides an air conditioning system which comprises a compressor, an indoor heat exchanger, an outdoor heat exchanger, a main expansion valve and a first hydrojet throttling element, wherein the compressor is provided with a hydrojet device; the indoor heat exchanger is communicated with the compressor; the outdoor heat exchanger is communicated with the compressor; the main expansion valve is communicated with the indoor heat exchanger and the outdoor heat exchanger respectively; and one end of the first hydrojet throttling element is communicated with the outdoor heat exchanger, and the other end of the first hydrojet throttling element is communicated with the hydrojet device. The circulation mode of the air conditioning system is improved by the arrangement of the first hydrojet throttling element, refrigerant is exhausted from the compressor and condensed in the outdoor heat exchanger, then one branch of the condensed refrigerant is throttled by the first hydrojet throttling element to become low-temperature medium-pressure two-phase refrigerant which enters the hydrojet device, the refrigerant entering the hydrojet device is sprayed out from the hydrojet device and mixed with the compressed refrigerant gas at a low-pressure side so as to reduce the temperature of the refrigerant, thus realizing temperature reduction of exhausted gas of the compressor, improving the reliability of the R32 compressor, and enhancing the applicability of an R32 refrigerant.

Description

technical field [0001] The present invention relates to the field of air conditioning, more specifically, to an air conditioning system. Background technique [0002] At present, the two main refrigerants used in the field of household air conditioners are R22 and R410A. Since R22 has a destructive effect on the atmospheric ozone layer, R410A belongs to HFCs and is a transitional substitute refrigerant for HCFCs (such as R22), with a high GWP value ( About 2100), these two refrigerants are bound to face elimination and replacement. [0003] R32 (difluoromethane, CH 2 f 2 ) Due to its ODP of 0, low GWP (about 675) and high system COP, it is considered to be one of the refrigerants that has the potential to replace R22 and R410A. However, because R32 has a higher discharge temperature, and the high discharge temperature affects the reliability of the compressor, this limits the use of R32. Contents of the invention [0004] The object of the present invention is to solve...
