Description

(1) Technical field: [0001] The invention relates to a double rolling rotor compressor. It belongs to the mechanical displacement type rotary compressor. (two) background technology: [0002] Rolling rotor compressor, also known as rolling piston refrigeration compressor, is widely used in household and commercial air conditioners and refrigeration devices. The reciprocating motion of the contacting slide plate realizes the refrigeration compressor of vapor compression. At present, the widely used ones are mainly small fully enclosed type, usually there are two types: horizontal type and vertical type. It is mainly composed of a liquid reservoir, a sealed container, and a motor part and a compression part arranged in the sealed container. The stator of the motor is fixed on the sealed container. In the container, the rotor of the motor is connected to the shaft of the eccentric wheel, and the accumulator plays the role of separating gas and liquid, storing refrigerant liqu...

AI Technical Summary

Problems solved by technology

[0010] 1. As we all know, previous refrigerants such as CFC and HCFC will cause damage to the ozone layer and must be phased out, while the current alternative refrigerants such as HFC and CO 2 Both require greater exhaust pressure, and greater exhaust pressure can easily cause deformation of the eccentric shaft of the compression part, especially in the section connecting the upper and lower eccentric wheels. The deformation of the eccentric shaft will cause the rotor to tilt. On the one hand, it causes the friction loss of the rotor relative to the end face of the sealed cylinder part, which increases the power loss; at the same time, it causes the wear of the parts and shortens the life of the compressor

The existing double-rotor rolling-rotor compressors cannot adapt to these alternative refrigerants that require higher discharge pressures

[0011] 2. The existing double-rotor rolling-rotor compressors all need to use exhaust valves. The exhaust valves not only increase resistance, cause power loss, but also emit noise, and are a vulnerable part

Especially at high speed, the defect of the exhaust valve is more prominent

[0012] 3. In order to improve the efficiency of the motor, the gap between the motor rotor and the stator is generally relatively small, while the displacement of the double-rotor rolling rotor compressor is generally relatively large, and it is difficult for the larger displacement to pass through the smaller motor rotor The gap between the stator and the stator, which causes the compressed high-pressure gas to not be discharged from the compressor in time
