Abstract

The invention discloses an air-conditioning system for replenishing air and increasing enthalpy and a control method thereof. An air-conditioning system for supplementing air and increasing enthalpy, including a compressor connected together to form a refrigerant circuit, an outdoor heat exchanger, a throttling device and an indoor heat exchanger, the compressor has a refrigerant suction port and a refrigerant discharge port, and the refrigerant of the compressor The suction port is connected with a bypass pipe, and the outdoor heat exchanger is provided with a first flow path and a second flow path for the refrigerant to flow through. The first flow path is connected between the refrigerant discharge port of the compressor and the throttling device, and the second flow path The inlet of the flow path is connected to the refrigerant outlet of the compressor, and the outlet of the second flow path is respectively connected to the throttling device and the bypass pipe through the valve assembly. The valve assembly is used to selectively block the second flow path, or make the second flow path Connect throttling device or bypass pipe. Realize the continuous refrigeration of the air-enhancing air-conditioning system in a low-temperature environment to improve user experience.

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...
