Evaporation temperature is high, low pressure is high.
蒸发温度高，低压压力也高。
The interlaced heat pump flow has a total temperature difference that is lower than other heat pump flows and can be applied to the low - temperature evaporation for the heat - sensitive materials.
间隔式多效热泵流程不但可以大幅节能，减少总温差费用支出，还能在更多效保持低温水平，非常适于热敏性物料的低温蒸发浓缩。
Thought water is a good refrigerant, it is difficult to be used directly in a common compression refrigeration system due to its very low pressure and vapor density at the evaporation temperature.
由于水的蒸发压力低、比容大使得水作为制冷剂直接用于压缩式制冷系统还有很大的困难。
