降低冷却水进口温度和提高其质量流量不仅有利于提高制冷性能系数，而且能降低最佳高压侧压力。
Reducing the inlet temperature of cooling water and increasing its mass flow are favorable to increase refrigerant performance coefficient, and can decrease optimal pressure at high pressure side.
质量浓度为5%的悬浮液在在整个质量流量范围内总是表现出比水好的冷却性能，它对应的是更低的壁面温度以及更好的传热系数。
The 5% suspension always shows better cooling performance than water with lower wall temperatures and enhanced heat transfer coefficient within the whole range of mass flow rates.
