Abstract

Embodiments of the present invention provide a heat exchange cycle system, a control method thereof, and an air conditioner, which relate to the technical field of air conditioning and are used to solve the problem of insufficient heating capacity of a multi-connected heat pump system in the prior art. The heat exchange cycle 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 circuit, an indoor heat exchange circuit, a first A solenoid valve, a second solenoid valve and a third solenoid valve. Embodiments of the invention are used in the manufacture of air conditioners.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat exchange cycle system, a control method thereof, and an air conditioner. Background technique [0002] The multi-connected heat pump system is favored by more and more consumers due to its advantages such as flexible and accurate control, good applicability of the unit, small building area occupied, and convenient installation and maintenance. [0003] Same as the traditional air conditioning system, the heating principle of the multi-connected 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 refrigerates the high-temperature and high-pressure gas. The heat released after the refrigerant condenses is sent out; then the high-temperature and high-pressure liquid refriger...
