The present invention provides an air conditioner, which includes a compressor and a main circulation circuit and an auxiliary circulation circuit connected to the compressor. The compressor includes a first compression chamber and a second compression chamber. The first compression chamber is connected in series in the main circulation circuit. The two compression chambers are connected in series in the auxiliary circuit; the air conditioner also includes a subcooling device arranged in the main circuit and the auxiliary circuit to subcool the refrigerant in the main circuit. Because the air conditioner of the present invention has two compression chambers, the first compression chamber of the compressor is connected in series in the main circuit circulation, and the second compression chamber is connected in series in the auxiliary circuit circulation; The refrigerant in the auxiliary circuit can reduce one auxiliary compressor and reduce the cost, volume and control complexity. By coupling the auxiliary circuit cycle with subcooling effect in the main circuit cycle, the subcooling degree of the refrigerant in the main circuit cycle can be increased, effectively improving the cooling capacity and energy efficiency ratio of the air conditioner during cooling, and the heating capacity and heating capacity during heating. coefficient of performance.
Description
Technical field [0001] The present invention relates to the field of air conditioners, and in particular to an air conditioner. Background technique [0002] The heating capacity of the air source heat pump decays rapidly as the outdoor ambient temperature drops, resulting in limited heating capacity of the air source heat pump when the ambient temperature is too low. It is necessary to turn on the electric heating device to assist heating to meet the heating needs of the user, reducing the heat pump unit efficiency. [0003] The use of mechanical subcooling cycle can significantly improve the capacity, energy efficiency ratio or performance coefficient of air conditioning or heat pump units. The mechanical subcooling cycle needs to be coupled with an auxiliary circuit cycle on the basis of the main circuit cycle. Generally, adding an auxiliary circuit cycle requires adding an auxiliary circuit compressor, which leads to an increase in cost, and also increases the volume and cont...
