Abstract

The invention discloses a compressing mechanism part and a compressor and a refrigerating plant with the compressing mechanism part. The compressing mechanism part comprises a double-cavity air cylinder, a piston and a sliding sheet; the double-cavity air cylinder is internally provided with a first air cylinder cavity and a first sliding sheet cavity, and the first sliding sheet cavity is constructed to be a first working cavity with variable internal pressure; the piston which eccentrically rotates is arranged in the first air cylinder cavity; the sliding sheet doing reciprocating motion is arranged in the first sliding sheet cavity, the first air cylinder cavity is divided into a first compression cavity and a first air suction cavity through the corresponding piston and the corresponding sliding sheet, the first compression cavity is provided with a first exhaust opening, the first air suction cavity is provided with a first air suction opening, the first working cavity is provided with a second air suction opening and a second exhausting opening, and the first exhausting opening is connected with the second air suction opening through a refrigerant channel. By means of the compressing mechanism part, secondary compression of one air cylinder on refrigerants can be achieved, the compressor production efficiency is improved, and the compressor manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a compression mechanism part, a compressor and a refrigeration device having the same. Background technique [0002] It is known that the lower the ambient temperature is, the higher the compression ratio of the compressor will be, so that the performance deterioration caused by internal leakage of the compression chamber and re-expansion of the clearance gas will be more serious. For this reason, in the compressor of the related art, the way of multi-stage compression is generally adopted to improve the above-mentioned phenomenon. The most common method at present is to use two cylinders to achieve two-stage compression, but the cost of the compressor is higher due to the addition of one cylinder body, and there are several friction pairs and gas leakage channels, making the compressor Performance is not ideal. In addition, at present, the temperature of the low-temperature environme...
