| Abstract: | To obtain the low temperature of 90 K, the Linder refrigeration cycle with pre-cooling cycle was set up. The pre-cooling cycle and refrigeration cycle of the system were designed. The refrigerants of pre-cooling cycle and refrigeration cycle were R404A and R740. The lowest temperature without heat loads was 90 K and the cooling capacity was 140 W. The system has simple structure and gets low temperature, which could be used widely in cryogenic regions. |
