Abstract

The invention relates to an asymmetric scroll compressor and an air conditioner. The compressor comprises a static scroll plate and a dynamic scroll plate, wherein the dynamic scroll plate is opposite to the static scroll plate, is rotatable relative to the static scroll plate and is provided with a back-pressure hole channel and a first hole channel; a compression cavity and a back-pressure chamber of the compressor can be communicated through the back-pressure hole channel; the first hole channel can be communicated with a pressurized air cavity in the compressor; a first airflow outlet of the first hole channel is symmetric to a second airflow outlet of the back-pressure hole channel relative to a rotating center of the dynamic scroll plate; the first hole channel can be communicated with the pressurized air cavity in the compressor, so that the direction of moment formed by pressurized airflow, passing the first hole channel, on the dynamic scroll plate is opposite to that of moment of pressurized airflow passing the back-pressure hole channel, influence of overturning moment on the dynamic scroll plate is reduced, and the stability of the asymmetric scroll compressor is improved.

Description

Technical field [0001] The invention relates to the technical field of compressors, in particular to an asymmetric scroll compressor and an air conditioner. Background technique [0002] At present, scroll compressors have attracted people's attention due to their compact structure, small size, light weight, stable operation, and high efficiency, and are widely used in many fields. When the scroll compressor is working, because the movable scroll bears the action of the axial gas force that changes with the rotation angle of the main shaft, it floats in the axial direction between the fixed scroll and the support body. The existence of axial gas force can not only cause the expansion of the axial gap of the compression chamber, increase leakage and reduce the volumetric efficiency, but also increase the friction power consumption. [0003] At present, the most commonly used method to balance the axial gas force is to adopt a back pressure structure, by opening a back pressure hole...
