Abstract

This invention relates to a gear-type contractor, which comprises motor, gear-type compressing part used for compressing coolant flow from evaporator by the driving of motor, and gear-type swelling part used for swelling the reflow coolant after flowing contractor and chiller; wherein the gear-type compressing part comprises main bearing, compressed cylinder, outer gear, inner gear and compressed plate; the gear-type swelling part comprises swelling plate, swelling cylinder, outer gear, inner gear, and supplementary bearing; the inner gears of compressing part and swelling part are mosaic connected with the rotation shaft of the motor. Said invention can increase the coefficient of performance of refrigerating system, and can use carbon dioxide to replace traditional coolant, which is benefit for environmental protection.

Description

technical field [0001] The invention relates to the field of gear type compressors. Background technique [0002] Generally, a compressor is a machine that uses the power of an electric motor or a steam turbine to pressurize working fluids such as air and 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. [0003] According to the type of compression, compressors can be divided into positive displacement compressors and turbo compressors. [0004] Among them, the positive displacement compressor is widely used in the production field. The compression method of the positive displacement compressor is to increase the pressure by reducing the volume. Positive displacement compressors can be divided into reciprocating compressors and rotary compressors. [0005] Reciprocating compressors use the reciprocating motion of a...
