Abstract

The invention discloses a gas-replenishing enthalpy-increasing air conditioner system and a control method of the gas-replenishing enthalpy-increasing air conditioner system. The gas-replenishing enthalpy-increasing air conditioner system comprises a compressor, an outdoor heat exchanger, a throttling device and an indoor heat exchanger which are connected together to form a refrigerant loop. The compressor is provided with a refrigerant suction inlet and a refrigerant discharge outlet. The refrigerant suction inlet of the compressor is connected with a bypass pipe. The outdoor heat exchanger is provided with a first flow path and a second flow path, wherein a refrigerant flows through the first flow path and the second flow path. The first flow path is connected between the refrigerant discharge outlet of the compressor and the throttling device. An inlet of the second flow path is connected with the refrigerant discharge outlet of the compressor. An outlet of the second flow path is connected with the throttling device and the bypass pipe through a valve assembly. The valve assembly is used for selectively enabling the second flow path to be cut off or communicate with the throttling device or the bypass pipe. Continuous refrigeration of the gas-replenishing enthalpy-increasing air conditioner system in the low-temperature environment is achieved, and therefore user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system for supplementing air and increasing enthalpy and a control method thereof. Background technique [0002] At present, the air conditioner is a household appliance commonly used in people's daily life. Generally, the air conditioner performs cooling and cooling when the external environment is relatively hot, and performs heating and heating when the external environment is relatively cold. In special cases, the air conditioner needs to perform cooling operation in a low-temperature environment. At this time, due to the good heat exchange effect, frost will appear on the indoor heat exchanger after the air conditioner has been running for a period of time. At this time, the air conditioner will stop. The compressor in the outdoor unit runs for defrosting. During actual use, the outdoor unit of the air conditioner will be turned on and off frequ...
