When the air conditioning system is too lightly loaded, the frequency of the compressor needs to be continuously reduced. However, the minimum amount of cooling that can be delivered by the compressor is limited due to the limitation of the minimum operating frequency of the compressor. Therefore, when the system load is less than the minimum output capacity of the compressor in the lowest frequency operation, the compressor is frequently started and stopped, so that the power consumption of the compressor is high, and when the frequency of the compressor is too low, the volumetric efficiency and the motor efficiency of the compressor are low, so that the low-frequency operation energy efficiency of the compressor is low. Therefore, the problem is solved by adopting a variable frequency and variable capacitance mode at present. The compressor adopts the double-cylinder structure, and through increasing the switching structure, realizes the operation of compressor single cylinder, double-cylinder two kinds of modes. Double cylinders are used under heavy load, and a single cylinder is used under light load. To realize the function, a slide sheet groove of the variable-volume cylinder needs to be sealed so as to control the movement of the slide sheet by introducing high pressure or low pressure into the slide sheet groove, when the high pressure is introduced into the slide sheet groove, the compressor is in a double-cylinder mode, and when the low pressure is introduced, the compressor is in a single-cylinder mode.
