Abstract

The embodiment of the invention provides a heat exchange circulating system and a control method thereof and an air conditioner, and relates to the technical field of air conditioners, which can solve the problem that the heating capacity of multi-online heat pump systems are inadequate in the prior art. The heat exchange circulating system includes a first compressor, a second compressor, a four-way reversing valve, a gas-liquid separator, a subcooler, a bypass electronic expansion valve, an outdoor heat exchange loop, an indoor heat exchange loop, a first solenoid valve, a second solenoid valve and a third solenoid valve. The embodiment of the invention is used for manufacturing of air conditioners.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a heat exchange cycle system, a control method thereof, and an air conditioner. Background technique [0002] The multi-line heat pump system is favored by more and more consumers due to its advantages such as flexible and accurate control, good unit applicability, small building area occupation, and convenient installation and maintenance. [0003] Similar to traditional air conditioning systems, the heating principle of the multi-line heat pump system is as follows: first the compressor sends the high temperature and high pressure gas refrigerant to the indoor heat exchanger for condensation to become a high temperature and high pressure liquid refrigerant, and the indoor unit cools the high temperature and high pressure gas The heat released after condensation of the refrigerant is sent out; then the high-temperature and high-pressure liquid refrigerant flows into th...
