Author(s) : WANG Y., SUN Y., WANG Q. X.

Summary

A kind of new type low temperature cabinet with big volume is introduced in detail. The low temperature cabinet adopts cascade refrigerating system which is composed of two single-stage compression refrigerating systems. R22 is selected to be refrigerant in the high temperature cycle system, and R13, is selected to be refrigerant in the low temperature cycle system. The R22 system can both operate alone and operate cascade with the R13 system. So the system can achieve two evaporative temperatures: -70 and -20°C. At the same time, the net volume of the low temperature cabinet is 0.216 m3. The refrigerating system of the low temperature cabinet can operate stably while the temperature is -70°C.
