| Abstract: | A kind of low-temperature refrigeration device with big capacity is studied in this article. The volume of the low-temperature cabinet in this device is 1.375m3（1.5m×1.5m×1.1m）, and the device is composed by double- refrigerant-system, including two single-stage compressors. R22 is selected as refrigerant in the high temperature system, while R23 is selected as refrigerant in the low temperature system. The high temperature system can reach to -35 ℃ when operates alone, the low temperature system can reach to -70℃ when it operates with the hign temperature system. This device can be used in many fields such as food industry, medical treatment, military engineering, aerospace and so on. |
