compressor

Abstract

The invention discloses a compressor which comprises a compressor shell, a pump body assembly, and a liquid storage device, wherein the pump body assembly is arranged in the compressor shell, the pump body assembly comprises a compression chamber and a pump body suction hole connected with the compression chamber; the liquid storage device comprises a liquid storage device shell and a discharge pipe, the discharge pipe extends into the pump body suction hole in a seal matched mode and is connected with the compression chamber, the discharge pipe comprises a discharge pipe external section positioned outside the liquid storage device shell, at least one part of the discharge pipe external section is made of the material, and the heat conductivity coefficient of the material is less than 10W / (m*k). According to the compressor, the heat-conducting property of the discharge pipe external section is reduced, heat transfer to the gas in the discharge pipe from the external environment and / or the inner wall of the pump body suction hole can be effectively isolated, the suction overheating can be effectively reduced, and the suction efficiency and energy efficiency of the compressor are improved; one part of the discharge pipe replaces original pump body suction pipe, so that the structure of the compressor is relatively simple and the cost is relatively low.

Description

technical field [0001] The invention relates to the field of compression equipment and refrigeration technology, and more specifically, to a compressor. Background technique [0002] Suction superheat is one of the main factors affecting the suction efficiency of compressors. The suction mode of the pump body of the compressor is usually set to radial suction, while the accumulator is axial suction. In order to facilitate the assembly of the accumulator, the discharge pipe of the accumulator usually needs to be made into a 90° elbow. In order to facilitate the bending process, its material is usually copper. At the same time, in order to improve the sealing performance between the suction pipe of the pump body and the cylinder, the suction pipe of the pump body is usually made of copper pipe. [0003] However, due to the high thermal conductivity of the copper tube, the copper tube exposed to the air and the suction pipe of the pump body connected to the inner wall of the ...

AI Technical Summary

Problems solved by technology

Since the specific volume of the heated gas will increase, the quality of the gas obtained in the suction chamber of the pump body will decrease, and the suction efficiency will decrease. At the same time, the overheated gas may also reduce the efficiency of the compressor.

In addition, the use of a large amount of copper also increases the cost of the compressor
