Problems solved by technology

Since the heat absorbed by the low-temperature refrigerant does not come from the cooled medium, the suction heat exchange inside the suction pipe is an ineffective heat exchange, which directly causes the increase of the suction specific volume, the decrease of the refrigerant circulation, and the reduction of the compression of the compressor. efficiency

Abstract

The invention discloses a compressor assembly. The compressor assembly includes: a compressor and a suction pipe assembly. The compressor includes a casing and a compression mechanism arranged in the casing. The compression mechanism has a compression chamber and communicates with the compression chamber. The suction hole, the suction pipe assembly includes a suction pipe, one end of the suction pipe is located outside the compressor, the other end passes through the shell and fits in the suction hole to supply refrigerant to the compression chamber, the inner diameter of the suction hole is D1 The outer diameter D2 of the other end of the suction pipe satisfies the relationship: D2‑D1≥0, and D2·(10·ρ2+1)‑D1·(10·ρ1+1)≥0. According to the compressor assembly of the present invention, the interference fit between the suction pipe and the suction hole can be realized at the working environment temperature of the compressor, thereby preventing gas leakage in the compression mechanism and improving the sealing performance of the compression mechanism.

Description

technical field [0001] The invention relates to the field of compressor equipment, in particular to a compressor assembly. Background technique [0002] During the operation of the compressor in the related art, affected by the ambient temperature inside the compressor, the connection between the suction pipe and the compression mechanism is easy to loosen, and problems such as air leakage occur, which leads to a decrease in the refrigerant circulation of the compressor, reducing Compression efficiency of the compressor. In addition, the high-temperature and high-pressure gas in the compressor shell has a large temperature difference with the low-temperature refrigerant in the suction pipe. The low-temperature refrigerant in the suction pipe directly absorbs heat from the gas in the shell through the suction pipe wall, making the suction heat exchange increase. Since the heat absorbed by the low-temperature refrigerant does not come from the cooled medium, the suction heat...
