Abstract

The invention provides a rotary piston compressor with a three-stage air supplementing function and an air conditioning system. The rotary piston compressor comprises a first-stage compression unit (10), a second-stage compression unit (20) and air supplementing devices; the first-stage compression unit (10) and the second-stage compression unit (20) each comprises an air cylinder, an end plate, a rotary piston and a sliding plate, each air cylinder is provided with an air inlet and an air outlet, the air supplementing devices are arranged on the second-stage compression unit (20), a pipe between the first-stage compression unit (10) and the second-stage compression unit (20) and the first-stage compression unit (10), and therefore the refrigerant flow is increased, and the refrigerant temperature is decreased. According to the technical scheme, the compressor refrigerant circulation amount is effectively improved, the refrigerant temperature in the compression process is decreased, and the compressor efficiency is improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rolling rotor compressor with three-stage air supplement and an air-conditioning system. Background technique [0002] At present, rolling rotor compressors are widely used in the field of household air conditioners, and they have the advantages of high efficiency, flexibility, and portability. However, when the rolling rotor compressor is used in low-temperature heating conditions, the following problems will occur: (1) The compressor suction specific volume increases, resulting in a decrease in the refrigerant circulation flow rate and attenuation of heating capacity; (2) an increase in the pressure ratio (3) The increase of the compressor pressure ratio at low temperature leads to an increase of refrigerant leakage during the compression process, which reduces the volumetric efficiency and isentropic efficiency of the compressor. The above-mentioned problems encountered by the ro...
