摘要
介绍一种混合工质制冷循环，以空气和水两种自然物质的混合物为工质，实现绝佳的环保性能．水的相变改善了空气的压缩和膨胀过程，同时又增加了制冷量，使循环具有很高的经济性．对循环进行了简单的热力分析，并在不同的给定条件下，对各点的状态参数和循环性能参数进行了理论计算．结果表明，在膨胀功充分利用的前提下，环保制冷循环的制冷系数COP=6～7．
A kind of refrigeration cycle was introduced. It used air/water mixture as refrigerant so as to be absolutely environmentally friendly. The process of air＇s condensation and expansion were improved by the water＇s transformation, which also increased the quantity of the refrigeration, which led to the cycle of higher economy. The state parameters of some specific points were calculated in different conditions. The results show that the refrigeration cycle can get a high COP of between 6 and 7, supposing the expansion power is fully made of use.
