Problems solved by technology
Most of the fishing boats use compression refrigeration with freon as the refrigerant. It mainly consists of compressors, condensers, expansion valves, and evaporation. Compression refrigeration mainly uses screw compressors for refrigeration, but screw compressors have hydraulic pressure. Oil is easy to generate heat and the heat is not easy to dissipate, and it is also easy to have the problem of oil circuit blockage. The main reason is that the current screw compressor does not have a filter, and there are many room for improvement as a whole.

The invention relates to a refrigerating compressor set which comprises a screw rod compressor. The screw rod compressor is connected with a motor through a shaft coupler and is connected with an economizer and an oil separator, and the economizer is connected with an oil cooler. The oil cooler is provided with an inner shell and an outer shell, and a cooling chamber is formed between the inner shell and the outer shell. An end cover is arranged at the end part of the oil cooler, and a cooling water inlet and a cooling water outlet communicating with the cooling chamber are formed in the end cover. The inner shell is connected with the screw rod compressor through an oil way circulation pipe. The oil cooler can lead out hydraulic oil in the refrigerating compressor set to timely cooling, so that the working efficiency of the refrigerating compressor set is ensured. The refrigerating compressor set integrates the screw rod compressor with the economizer, the oil separator, an oil filterand the oil cooler and ensures the hydraulic oil quality and performance of the screw rod compressor, thereby achieving the best cooling effect.
Description
technical field [0001] The invention relates to a refrigeration compressor unit. Background technique [0002] There are a series of problems such as complex system, aging technology, high energy consumption and low level of operation and management of fishing vessel refrigeration equipment. In view of these problems, let's talk about the scientific management of fishing boat refrigeration equipment. 1. The working principle and process of the fishing boat refrigeration system. 1. Working principle: There are three common refrigeration methods at present. Namely: compression refrigeration, absorption refrigeration and steam injection refrigeration. Most of the fishing boats use compression refrigeration with freon as the refrigerant. It mainly consists of compressors, condensers, expansion valves, and evaporation. Compression refrigeration mainly uses screw compressors for refrigeration, but screw compressors have hydraulic pressure. Oil is easy to generate heat and the ...
