制冷系统是为了实现从低温部份向高温部份的热的转移,为此必须消耗能量。制冷系统的效果可以用制冷系数ε来表示。ε=Q_0/Al,即系统中制取的冷量和输入功率或热量之比。逆卡诺循环的制冷系数最大,可用下式表示:
The refrigeration system is designed to transfer the heat from the cryogenic section to the hot section, for which energy must be dissipated. The effect of the refrigeration system can be expressed by the refrigeration coefficient ε. ε = Q_0 / Al, which is the system of refrigeration and input power or heat ratio. Reverse Carnot refrigeration cycle maximum coefficient, can be expressed as follows:
