Oil and gas separation type air conditioning compressor

Abstract

The invention relates to an oil and gas separation type air condition compressor; a working crescent cavity is sequentially divided into a suction chamber, a first lubrication oil chamber, a second lubrication oil chamber and a discharge chamber which do not communicate with each other by a first sliding baffle, a second sliding baffle and a third sliding baffle. The oil and gas separation type air condition compressor achieves separation of lubrication oils and a refrigerant, namely achieves independent lubrication and sealing of the lubricating oils, reduces the volume of the lubricating oils occupying the working crescent cavity, relatively increases the refrigerant occupying space, thereby increasing the discharge capacity of the compressor. When the air conditioner compressor is applied to an air conditioner, an eccentric rotor is not obstructed by the viscosity of the lubricating oils, and the power consumption of the compressor is greatly reduced, no lubricating oils are attached onto the inner wall of a copper tube, and thus the heat exchange is enhanced. The air condition compressor has the advantages of simple structure, low cost and good effect. In addition, two lubricating oil chambers are adopted, and lubrication with different lubricating oils can be achieved through switching. The adaptability of the compressor in different environments is greatly improved.

Description

technical field [0001] The invention belongs to the field of air-conditioning compressors, and in particular relates to a rotor-type oil-gas separation type air-conditioning compressor, which can be applied not only to single-rotor compressors, but also to multi-rotor compressors. Background technique [0002] The rotary compressor is a volumetric rotary compressor. The change of the working volume of the cylinder is realized by the rotation of an eccentric device in the cylinder. The cylinder body is composed of a cylinder body and a sealing end cover. The eccentric device includes a main shaft, an eccentric rotor and a rotary sleeve. The main shaft and the eccentric rotor are integrally formed, and the rotary sleeve is sleeved on the outer periphery of the eccentric rotor to form the eccentric device. In the working state, the eccentric device inscribes with the cylinder body and always rolls along the inner wall of the cylinder body to form a working crescent cavity. Th...

Problems solved by technology

[0005] Although the rotary compressor adopts the above-mentioned second lubrication method to solve the problem of lubrication and sealing between the outer peripheral surface of the rotary sleeve and the inner wall of the cylinder body, it also has the following disadvantages when used in air conditioners: (1). The cylinder of the compressor occupies the volume of the basic unit of the compressor cavity. Since the volume of the compressor unit is fixed, relatively speaking, the space occupied by the refrigerant is correspondingly reduced. For the same compressor, its refrigerant displacement is Reduce; the higher the temperature of the compressor, the faster the vaporization of the lubricating oil, the larger the space occupied, and the more lubricating oil is taken away into the pipeline; (2), the lubricating oil is viscous, and the compressor is working , the presence of lubricating oil will virtually increase the damping of rotor rotation, thereby increasing the power consumption of the compressor; (3), lubricating oil and refrigerant mix and flow in the air conditioner pipeline, which will cause the lubricating oil to adhere to The inner wall of the copper tube forms an oil film insulation layer, and the refrigerant needs to pass through the oil film insulation layer to exchange heat, so it will greatly affect the heat exchange of the refrigerant, thereby reducing the efficiency of the entire system

[0006] In addition, the air conditioner compressors in the prior art can only be lubricated with one kind of lubricating oil, and the lubricating oil of the compressor cannot be replaced. ) under the same lubricating oil, the effect is very different
