Compressor and compressor set

Abstract

The invention relates to a compressor and a compressor set. The compressor comprises a compressor body, an air suction end and an electrical box, wherein the air suction end is arranged outside the compressor body, and connected with an air inlet of the compressor; the electrical box is arranged outside the compressor body; and the air suction end is adjacent to a high-temperature side of the electrical box. The compressor set comprises a plurality of compressors, a set air suction end and a plurality of electrical boxes, wherein the compressors are connected in parallel; the set air suction end is connected with an air inlet of the outermost compressor; and the set air suction end is adjacent to a high-temperature side of the nearest electrical box to achieve a heat dissipation purpose for the electrical box.

Description

technical field [0001] The invention relates to an internal arrangement form of a machine, in particular to an internal arrangement form of a compressor and a compressor group. Background technique [0002] In the prior art, the number of compressors used in parallel units is generally 2 to 6 or even more, and there are relatively many components in the electrical box matched with the compressor. The temperature can reach about 80 degrees Celsius, and the high temperature is a severe test for the reliable operation of the components. [0003] Faced with the serious problem of electrical box heating, methods such as increasing the size of the electrical box and adding cooling fans are generally adopted. These methods undoubtedly increase the electrical box's requirements for space and rain resistance. In addition, the suction temperature of the compressor is low at low temperature, and the suction superheat in the compressor is too low, which can easily cause the compressor ...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the number of compressors used in parallel units is generally 2 to 6 or even more, and there are relatively many components in the electrical box matching the compressor. Due to the large heat generated inside the electrical box, some components themselves The temperature can reach about 80 degrees Celsius. Excessively high temperature is a severe test for the reliability of components.

[0003] Faced with the serious problem of heat generation in the electrical box, methods such as increasing the size of the electrical box and adding cooling fans are generally adopted. These methods undoubtedly increase the requirements for the space of the electrical box and the requirements for the rainproof level, etc.

In addition, when the compressor is at a low temperature, the suction temperature is low, and the suction superheat in the compressor is too low, which can easily cause the compressor to carry liquid.
