摘　　要：通过对空气源热泵热水器样机实验分析了其存在的相关问题,在这基础上提出了蓄热型空气源复叠式热泵热水器系统,并且通过初步理论计算得出该系统在相同的工况下能够达到较高的COP值。同时系统采用蓄热型水箱,减少水箱体积,具有良好的经济性。Many disadvantages were presented by the experiment of air source heat pump water heater.Therefore, cascade air source heat pump water heater （CASHPWH） with phase change materials （PCM） for thermal storage is introduced on the basis of the experiment.And the COP value of CASHPWH is also higher than that of the application at the same circumstance temperature by the primary theoretical calculation. Moreover, the economic advantage is stated by reducing the size of water tank because of the thermal storage.
