Problems solved by technology

[0002] In order to improve the stability of the refrigeration device in the ultra-low temperature environment, a part of the refrigeration device chooses a two-stage compression system, and its disadvantage is that the energy efficiency of the comprehensive application is low
The inventors found that in related technologies, the two-stage compression system cannot select the working mode according to the load conditions, resulting in low energy efficiency. The cylinder ratio is fixed, and the two-stage compression system is not energy efficient under low pressure ratio conditions

Abstract

The invention discloses a refrigeration device, comprising a first compressor, a second compressor, a first heat exchanger, a second heat exchanger and a flash vaporization device; the flash vaporization device is connected between one end of the first heat exchanger and one end of the second heat exchanger, and an exhaust port of the flash vaporization device is connected to an air suction port of the first compressor; the other end of the first heat exchanger is connected to an exhaust port of the first compressor and is selectively connected to an exhaust port of the second compressor; the other end of the second heat exchanger is connected to an air suction port of the second compressor and is selectively connected to the air suction port of the first compressor; and the exhaust port of the second compressor is selectively connected to the other end of the first heat exchanger. The refrigeration device of embodiments of the invention has multiple working modes to adaptive various load requirements and is wide in operation range, and the refrigeration device is high in actual operation energy efficiency and good in energy-saving effect.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a refrigeration device. Background technique [0002] In order to improve the stability of the refrigeration device in the ultra-low temperature environment, some refrigeration devices have selected a two-stage compression system, which has the disadvantage of low energy efficiency for comprehensive applications. The inventors found that in related technologies, the two-stage compression system cannot select the working mode according to the load conditions, resulting in low energy efficiency. The cylinder ratio is fixed, and the two-stage compression system is not energy efficient under low pressure ratio conditions. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a kind of, described [0004] The refrigerating device acc...
