摘 要:
为了获得90K的低温，提出1套带预冷循环的林德制冷系统，并分别对该系统的预冷循环和制冷循环进行了设计。预冷系统和制冷循环的制冷剂分别为R404A和R740。无热负荷时，设定低温箱的温度90K，制冷量为140W。该系统整体结构简单，获取温度低，在低温领域有较广泛的应用。[著者文摘]

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.[著者文摘]
