Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] A new type of cascade refrigeration system, including a primary refrigeration system and multiple secondary refrigeration systems, the primary refrigeration system is sequentially connected in series with a primary compressor 1, a condenser 2, a primary capillary tube 3 and a heat exchanger 4. The first-stage compressor 1 and the condenser 2 are connected through a first-stage compressor exhaust pipe 5 , and the heat exchanger 4 and the first-stage compressor 1 are connected through a first-stage compressor air return pipe 6 . The plurality of secondary refrigeration systems have the same structure, each secondary refrigeration system includes a secondary compressor 7, the secondary compressor 7 is connected to the condenser 2 in the primary refrigeration system, and the condenser 2 is connected to the primary refrigeration system The heat exchanger 4 in the ref...

Abstract

The invention discloses a novel cascade refrigeration system which comprises a first-level refrigeration system body and a plurality of second-level refrigeration system bodies. The first-level refrigeration system is sequentially serially connected with a first-level compressor, a condenser, a first-level capillary tube and a heat exchanger, the first-level compressor is connected with the condenser through a first-level compressor exhaust pipe, and the heat exchanger pipe is connected with the first-level compressor through a first-level compressor muffler; the second-level refrigeration system bodies are identical in structure, each second-level refrigeration system body comprises a second-level compressor which is connected with the condenser in the first-level refrigeration system body, the condenser is further connected with the heat exchanger in the first-level refrigeration system body, each second-level refrigeration system body further comprises a second-level capillary tube and an evaporator, one end of the second-level capillary tube is connected with the heat exchanger while the other end is connected with the evaporator, and the evaporator is connected with the second-level compressor. The double-compressor is adopted to control temperature refrigerating independently, the two second-level compressors are not affected with each other in refrigeration, cooling time is greatly shortened, and energy consumption is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, in particular to a novel cascade refrigeration system used in a large-capacity low-temperature preservation box. Background technique [0002] With the advancement of science and technology, refrigeration methods are becoming more and more diverse, but low refrigeration efficiency is a key problem that has not been resolved for a long time. The present invention studies large-capacity ultra-low temperature refrigerators and finds that traditional cascade refrigeration method ultra-low temperature refrigerators have defects such as high energy consumption, low refrigeration efficiency, and long refrigeration time. Contents of the invention [0003] The object of the present invention is to provide a new type of cascade refrigeration system, which solves the defects of the above-mentioned traditional cascade refrigeration method, is simple and convenient to use, has high refrigeration effec...
