PERFORMANCE OF LOW TEMPERATURE COOLING CIRCULATOR WITH AUTO-CASCADE REFRIGERATION SYSTEM

摘要：

Simply introduction of the application and basic principle of low temperature cooling circulator is given in the paper, the entireness in series auto-cascade refrigeration system is put forward, the result of compared this system with series-parallel connection system showed that the anterior is preferable. Some experiments were carried out on 5 liter and -100℃ (173.15K) low temperature liquid circulator using the system with non-azeotrope mixed refrigerant composed with R134/R23/R14, included cooling characteristic of circulator and throttled in every capillary tube; suction and exhaust pressure during cooling process; relationships between cooling capacity and refrigeration temperature as well as ambient temperature, some important conclusions have been obtained from those investigations.
