【摘要】 冷库微机控制与常规自动控制相比 ,其优越性在于它可根据库温变化自动地调整其制冷剂的蒸发温度 ,并使得其制冷剂和蒸发温度与冷库温差总是处于最小值。根据热力学第二定律 ,在其他条件不变的情况下 ,此时制冷装置的能耗最小。更多还原

【Abstract】 The evaporation temperature of refrigerant in a refrigerating plant with a computer-based-control system is much easier to be controlled than that in those without computer.Meanwhile the temperature difference between the evaporator and the storeroom will be able to be kept within minimun,which means,according to the second law of thermodynamics,the lowest energy consumption.更多还原
