Title:
AIR CONDITIONER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/128278
Kind Code:
A1
Abstract:
An air conditioner system comprises a compressor (1), an outdoor heat exchanger (2), an indoor heat exchanger (4), an auxiliary heat exchanger (3) and an injector (5), the compressor (1), the outdoor heat exchanger (2), the auxiliary heat exchanger (3), the indoor heat exchanger (4) and the injector (5) forming a main circuit of refrigerant circulation; the compressor (1), the outdoor heat exchanger (2), the indoor heat exchanger (4), the auxiliary heat exchanger (3) and the injector group (5) forming a branch circuit of refrigerant circulation. In the refrigeration/heating cycle, a part of the refrigerant flowing out from the compressor (1) flows into the injector (5) along the main circuit, and the other part of the refrigerant flows into the injector (5) along the branch circuit, and the two parts of refrigerant are mixed in the injector (5) and then returned to the compressor (1). The air conditioner system uses the auxiliary heat exchanger (3) to increase the overcooling effect of the refrigerant, and uses the injector (5) to increase the suction pressure of the compressor (1) so as to achieve the purpose of pressure increase and effect improvement, improving the refrigeration effect of the air conditioner in a high-temperature environment and the heat effect thereof in a low-temperature environment, and reducing energy consumption.
