Problems solved by technology
However, when the ambient temperature is too low in winter in the north, when the heat pump air conditioner is used for heating, the heat exchange capacity of the outdoor unit decreases, the return air volume of the normal return air port of the compressor decreases, and the power of the compressor decreases.
The pressure difference between the suction and exhaust of the compressor increases, which leads to a decrease in the circulation flow of the refrigerant in the air conditioning system, thereby reducing the heat provided by the phase room of the heat pump air conditioner and reducing the heating energy efficiency.

The invention discloses an air-conditioning system and an air conditioner, wherein the air-conditioning system includes: a refrigerant pipeline and a compressor connected in sequence by the refrigerant pipeline, a first heat exchanger, a balance tank, a first throttling device, a flash evaporator and The second heat exchanger: the refrigerant in the refrigerant pipeline enters the balance tank through the first heat exchanger after being compressed by the compressor, and at least part of the refrigerant in the balance tank enters the flash through the first throttling device An evaporator, the refrigerant is separated into a gaseous refrigerant and a liquid refrigerant in the flash evaporator, the separated gaseous refrigerant enters the compressor through the gas supply outlet and the gas supply inlet, and the separated liquid refrigerant passes through the second heat exchange device into the compressor. The air-conditioning system of the technical solution of the present invention adds a flash evaporator to improve the working energy efficiency of the compressor, and adds a balance tank to solve the problem of low heat exchange efficiency caused by too much liquid refrigerant in the first heat exchanger, and improves the production efficiency of the air-conditioning system. thermal energy efficiency.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and an air conditioner with the air conditioning system. Background technique [0002] As an energy-saving and environment-friendly heating technology, heat pump air conditioners are more and more widely used. However, when the ambient temperature is too low in winter in the north, when the heat pump air conditioner is used for heating, the heat exchange capacity of the outdoor unit decreases, the return air volume of the normal return air port of the compressor decreases, and the power of the compressor decreases. The pressure difference between the suction and exhaust of the compressor increases, resulting in a decrease in the circulation flow of the refrigerant in the air conditioning system, thereby reducing the heat provided by the phase room of the heat pump air conditioner and reducing the heating energy efficiency.
