Problems solved by technology

However, most of the existing modular unit oil equalization methods use three controls, that is, the modular unit needs to be connected in parallel with the oil equalization pipe for oil equalization between the modular units in addition to the parallel gas pipe and liquid pipe. The increase of the modular unit oil equalization pipe, It makes the installation, commissioning and maintenance of the unit more complicated and the cost is higher

Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] Such as figure 1 As shown, the compressor module according to the present invention includes: at least two compressors, at least two compressors have oil equalization holes, and at least two compressors are connected in parallel with each other; oil separator 4, the inlet of oil separator 4 and The exhaust ports of at least two compressors are connected, and the oil return port of the oil separator 4 is connected with the suction ports of at least two compressors; the first oil equalizing pipe, the first end of the first oil equalizing pipe is connected with at least two compressors The oil equalizing hole of the first oil equalizing pipe communicates with the inlet of the oil separator 4 at the second end.

[0025] The present invention arranges the first oil equalizing pipe so that the oil-rich compressor discharges the oil higher than the oil eq...

Abstract

A compressor module comprises at least two compressors (1, 2) both provided with an oil-balancing hole and connected in parallel to each other; an oil separator (4) with an inlet communicated with the discharge ports of the at least two compressors (1, 2) and an oil-return port communicated with the suction ports of the at least two compressors (1, 2); and a first oil-balancing pipe with the first end communicated with the oil-balancing holes of the at least two compressors (1, 2) and the second end communicated with the inlet of the oil separator (4).

Description

technical field [0001] The invention relates to the field of compressor unit control, in particular to a compressor module, a multi-module unit, and a multi-module unit oil equalization control method. Background technique [0002] The compressor is the "heart" of the air conditioner. When the compressor is working, there is a lot of friction inside. In order to ensure the reliable operation of the compressor and improve the performance of the compressor, lubrication is one of the important links, so the lubricating oil has a great impact on the compressor. Lubricating oil has the functions of lubricating, cooling and sealing the compressor. Moreover, the compressor requires a certain amount of lubricating oil. If there is too little lubricating oil in the compressor, the lubrication will be insufficient, and the compressor will be damaged. Therefore, a certain amount of oil storage is the most basic condition to ensure the reliable operation of the compressor. Only when th...
