Embodiment Construction

[0045] Such as Figure 3 to Figure 5As shown, the gear compressor provided by the present invention includes a casing 1 , a driving part 2 , a gear compression part 3 and a gear expansion part 4 . The casing 1 has a certain internal space. The drive unit 2 is provided inside the housing 1 . The gear type compression part 3 uses the power provided by the driving part 2 to compress the refrigerant discharged from the evaporator 6 . The refrigerant discharged from the gear-type compression part 3 flows through the condenser 5 and then flows into the gear-type expansion part 4 inside the compressor for expansion. The driving part 2 is a motor composed of a stator 200 arranged on the inner wall of the housing 1 and a rotor 210 arranged at the center of the stator 200 . After the power is turned on through the power terminal 110 , the rotor 210 can rotate. The gear type compression part 3 includes a main bearing 300 , a compression cylinder 310 , an external gear 320 , an intern...

Abstract

This invention relates to a gear-type contractor, which comprises the driving part, and the compressing part set above the driving part, characterized in that it uses the dynamic from the driving part to compress the coolant flow from the evaporator; and above the compressing part there is a gear-type swelling part, which will swell the reflow coolant after it flow from compressing part and chiller. Said contractor can increase the coefficient of performance of refrigerating system, and can use carbon dioxide to replace traditional coolant, which is benefit for environmental protection; besides, the force and force moment of the inner gear and outer gear of said contractor are balance, so it can decrease the shake and noise when operating.

Description

technical field [0001] The invention relates to a compressor, in particular to a gear compressor. Background technique [0002] Generally, a compressor is a device that uses the power of a driving unit or a steam turbine to pressurize a working fluid such as air or refrigerant to increase the pressure of the working fluid. This kind of compressor is widely used in the fields of home appliances such as air conditioners and refrigerators, as well as in production fields. According to the type of compression, compressors can be divided into positive displacement compressors and turbo compressors. Among them, the compressor widely used in the production field is a positive displacement compressor, which adopts a compression method that increases pressure by reducing volume. Such positive displacement compressors can be classified into reciprocating compressors and rotary compressors. The reciprocating compressor uses the reciprocating motion of the piston inside the cylinder ...
