Abstract

The invention discloses a heat pump air conditioning system and a control method thereof. The heat pump air conditioning system comprises a compressor, a four-way valve, an evaporator, a condenser, a first throttling device, a second throttle device, a heat recovery device and a heat exchange device; heat exchange is performed on a refrigerant which is located in a first channel and a refrigerant which is located in a second channel in the heat recovery device; heat exchange is performed on a refrigerant which is located in a third channel and a refrigerant which is located in a fourth channel in the heat exchange device. According to the heat pump air conditioning system, a gaseous refrigerant which is supplied by the heat exchange device is added into the compressor when the heat pump air conditioning system is located in the low temperature state and accordingly the heating capacity is ensured when the heat pump air conditioning system is located in the low temperature state, the displacement of the exhaust opening of the compressor is ensured, the exhaust temperature is reduced, and meanwhile the damage to the compressor due to liquid impact of the refrigerants is prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a heat pump air conditioning system and a control method thereof. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, the use of air conditioners has become a necessity in human life to improve the office environment. At low ambient temperature or in cold regions, as the ambient temperature drops, the evaporation temperature of the air conditioner will continue to decrease, resulting in a significant decline in the heating capacity of the working medium in the air conditioner, and the refrigerant flow rate at the suction port of the compressor is much lower than that of the compressor. The rated capacity of the motor, the capacity of the compressor is not fully utilized, and the internal motor of the compressor cannot be fully dissipated. In addition, the decrease in refrigerant fl...
