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 refrigerating cycle of mixed working medium is introduced to realize excellent environmental performance by taking a mixture of air and water as natural substances.The phase change of water improves the process of air compression and expansion while increasing the cooling capacity, Which makes the cycle highly economical.The simple thermodynamic analysis of the cycle is carried out and the state parameters and cycle performance parameters of each point are theoretically calculated under different given conditions.The results show that when the expansion work is fully utilized Under the premise of environmental protection refrigeration cycle refrigeration coefficient COP = 6 ~ 7.
