摘要
考虑到制冷系统蒸发温度(压力)越高,制冷效率越高。文中设计了一种周期性变蒸发温度冷水机组系统,它通过周期性地提高蒸发温度(压力),使系统平均当量蒸发温度提高,从而提高制冷系统热效率;并运用熵理论对本系统变温蒸发效率进行分析,得出该系统制冷效率有较可观的提高。
Abstract：Considering the higher evaporation temperature or pressure, the higher refrigeration efficiency could be. This paper designed a kind of periodic variable evaporating temperature chiller system. It can increase evaporation temperature or pressure periodically, so as to improve refrigeration system thermal efficiency. And analyzing the efficiency of this variable tempera- ture evaporation system by using the entropy theory. The conclusion is that the efficiency of this water chilling unit system has a considerable increase.
