二十五:运转参数蒸发温度 t_0。和冷凝温度 t_k 对制冷量 Q_0 轴功率 Ne 有什么影响?一台制冷机,由于使用的温度要求各异,会在不同的蒸发温度下工作,又因使用的地区和季节不同,冷凝温度亦会有所变化。由于运行的温度参数发生变化,制冷机的制冷量与所消耗的轴功率也随着改变,其变化的关系是:1.当蒸发温度 t_0不变时,冷凝温度 t_k 升高,则制冷量 Q_0减少,轴功率 N_e 增大。
Twenty-five: Operating parameters Evaporation temperature t_0. And condensing temperature t_k on cooling capacity Q_0 Shaft power Ne What are the effects? A refrigerator, due to the use of different temperature requirements, will work under different evaporation temperature, and because of the use of different regions and the season, the condensation temperature will Some changes. As the operating temperature parameters change, the cooling capacity of the refrigerator and the shaft power consumption also changes with the change of the relationship is: 1. When the evaporation temperature t_0 unchanged, the condensation temperature t_k increased, the cooling capacity Q_0 Decrease, shaft power N_e increases.
