Embodiment Construction

[0029] In order to help those skilled in the art to accurately understand the subject matter claimed in the present application, the specific implementation manners of the present application will be described in detail below in conjunction with the accompanying drawings.

[0030] figure 1 It is an embodiment of the refrigeration system involved in this application. see figure 1 , the refrigeration system includes a first compressor 12 and a second compressor 14 . The refrigerant passes through the first and second compressors 12, 14 through a two-stage compression refrigeration cycle. The first compressor 12 is configured as an intermediate temperature compressor, the second compressor 14 is configured as a low temperature compressor, and the compressed refrigerant leaving the second compressor 14 is sucked into the first compressor 12 for further compression. Due to the development of production, the requirements for refrigeration temperature are getting higher and higher...

Abstract

The invention discloses a refrigeration system. The refrigeration system comprises an ejector pump, the ejector pump is provided with a primary inlet, a secondary inlet and an outlet, the primary inlet is configured to be connected to an exhaust port of a compressor, part of refrigerant exiting via a liquid outlet of a first gas-liquid separation device enters the ejector pump, and the outlet is connected to the first gas-liquid separation device through a pipeline. According to the refrigeration system, the ejector pump is used for replacing a traditional refrigerant pump, the system cost canbe remarkably reduced, and the characteristics of energy conservation and high efficiency are achieved.

Description

technical field [0001] The application belongs to the refrigeration field, and in particular relates to a refrigeration system. Background technique [0002] In refrigeration systems, refrigerant liquid pumps are used to pump liquid refrigerant on the pipeline to remove excess liquid supply or to pressurize. For example, in conventional or transcritical refrigeration systems, refrigerant liquid pumps are used to obtain flooded evaporative operation. In ejector systems, the refrigerant liquid pump can also be used to increase the pressure of the liquid leaving the receiver tank, which receives the high pressure refrigerant and separates out the flash gas, to avoid starvation of the evaporator. However, refrigerant liquid pumps are expensive and difficult to maintain. Contents of the invention [0003] The technical problem to be solved in this application is to provide a refrigeration system to improve or replace the technical solution of the refrigeration system in the p...
