Embodiment Construction

[0014] The following description of the preferred embodiments is exemplary only, and in no way limits the invention, its application or usage. The same reference numerals are used to denote the same components in the various drawings, and thus the configuration of the same components will not be described repeatedly.

[0015] first refer to Figure 1-3 The basic construction and principles of conventional compressor systems are described.

[0016] like figure 1 As shown, the compressor system 10 includes a first compressor 100 and a second compressor 200 . The first compressor 100 and the second compressor 200 are connected in parallel with each other to constitute a so-called dual-line system. More specifically, the first compressor 100 may include a first casing 110 and a first intake port 118 and a first exhaust port 119 provided on the first casing 110 . The first housing 110 may include a first suction pressure region and a first exhaust pressure region (refer to late...

Abstract

The invention relates to a compressor system (10A) and a control method thereof. The compressor system comprises a first compressor (100) and a second compressor (200) which are connected with each other in parallel, a lubricant equalizing pipe (330) disposed between the first compressor and the second compressor, and a fluid introducing pipe (340); the fluid introducing pipe is configured to selectively introduce fluid under a discharge pressure inside the compressor system into the lubricant equalizing pipe to block the flowing of lubricants between the first compressor and the second compressor. The compressor system and the control method thereof of the invention can further improve the lubricant balance between the two compressors.

Description

technical field [0001] The present invention relates to a compressor system and a control method thereof. Background technique [0002] The content in this section merely provides background information related to the present disclosure and may not constitute prior art. [0003] A compressor system is known which consists of two or more compressors in parallel. Such a compressor system can utilize multiple compressors with relatively small cooling capacity to replace a single compressor with larger cooling capacity, thereby reducing the cost of the system and improving the operating efficiency of the system. In such a compressor system consisting of a plurality of compressors in parallel, an important issue is to ensure the lubricant balance among the compressors. Although various approaches have been proposed to improve the lubricant balance in such compressor systems, there is still improvement in the lubricant balance in such compressor systems, especially when variable...
