Abstract

The invention provides an air conditioning system which comprises a refrigerant cycle. The refrigerant cycle comprises an indoor heat exchanger, an outdoor heat exchanger and a gas-liquid separator. The gas-liquid separator is provided with a separator inlet, a separator gas outlet and a separator liquid outlet. The air conditioning system is characterized in that the air conditioning system further comprises an injector, and the injector is provided with an injector main inlet, an injector lateral inlet and an injector outlet; during refrigerating of the air conditioning system, the outdoor heat exchanger communicates with the injector main inlet, the indoor heat exchanger communicates with the injector lateral inlet, and the injector outlet communicates with the separator inlet; and during heating of the air conditioning system, the indoor heat exchanger communicates with the outdoor heat exchanger, and the outdoor heat exchanger communicates with the separator inlet. According to the technical scheme, the problems that in the prior art, the load requirement and the high and low pressure ratio of a compressor of an air conditioning system are large, the compressor needs to keep high frequency for operation, and use reliability is low can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular to an air conditioning system. Background technique [0002] At present, if the outdoor ambient temperature is very high (for example, the outdoor ambient temperature is above 50° C.), the cooling capacity and energy efficiency of the air-conditioning system will decrease greatly. In order to ensure the cooling effect, it is necessary to increase the cooling capacity and energy efficiency of the air-conditioning system. The compressor of the air-conditioning system has a large load demand and a large high-to-low pressure ratio. The compressor needs to maintain a high frequency of operation, and its reliability is low. Contents of the invention [0003] The main purpose of the present invention is to provide an air-conditioning system to solve the problems in the prior art that the compressor of the air-conditioning system has a large load demand, a large hi...
