- Abstract
- Nowadays, demands on super low temperature condition for industrial and comercial uses arethriving. Considering of its wide application in the present and the future, study of the super-low temperature refrigeration system should be actively carried out. This study is aimed to investigate refrigeration capacity and coeficient of performance(COP) of the cascade refrigeration system, as wel as to get the system which can reach evaporator of -70℃. For this purpose, R290 and R170 are charged in high stage and low stage respectively. Finally the characteristics of system using R290 and R170 wil be proposed. Additionaly, In this experiment, the flow rate of air flowing through the LS evaporator and the compressor inlet pressure were varied to investigate the refrigeration capacity and coefficient of performance characteristics.
