Abstract

The invention discloses a scroll refrigeration compressor with a suction supercharging function. The scroll refrigeration compressor comprises a compressor shell, a compression device and a suction supercharging device, wherein a machine body suction channel is formed in the compressor shell, an air inlet of the machine body suction channel is formed in a front turbine cover of the compressor shell, an air outlet is formed in a rear cover of the compressor shell; the compression device comprises an eccentric driving shaft, a motor stator, a motor rotor, a dynamic scroll plate and a static scroll plate, and the motor rotor is arranged in the motor stator and is connected with the eccentric driving shaft; the dynamic scroll plate is fixed to one end of the eccentric driving shaft and mesheswith the static scroll plate to form a crescent-shaped working chamber; and the suction supercharging device is arranged in the machine body suction channel to increase the pressure and flow rate of refrigerant gas entering into the crescent-shaped working chamber. The scroll refrigeration compressor can increase the pressure and flow rate of the refrigerant gas entering into a compression chamberto ensure the operation demand of an air conditioning system.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a scroll refrigeration compressor with suction boost. Background technique [0002] Scroll refrigeration compressors usually have constant compression. When the speed is constant, changes in working conditions will lead to over-compression and under-compression, and the work efficiency will decrease. When the external ambient temperature is too low, or other working conditions change, the pressure and flow rate of the refrigerant absorbed by the compressor become smaller, which cannot meet the operation requirements of the air conditioning system. [0003] At present, scroll refrigeration compressors with intermediate air supply and variable displacement have appeared, which can improve the working performance of scroll refrigeration compressors. The scroll refrigeration compressor with intermediate air supply refers to the design of air supply holes on the static scroll of the compre...
