摘　　要：为使热泵热水器在满足制热性的基础上兼顾经济性,提出了复叠式结构和蓄热器耦合的新型热泵热水器,探讨了它的性能,着重分析了经济性。结果表明该热水器的能效比高,工作温差大,适用区域广,在实行峰谷电价时经济性好,因而具有较高的应用价值。In order to give attention to the economy of HPWH based on the satisfaction of its ability of heating, this article puts forward a new kind of HPWH which is a coupling of a cascade structure and a heat conservation implement filled with PCM （Phase Change Materials）. Its pefformance is discussed and its economy capability is analyzed emphatically. The results show that this kind of water heater has a high cop and a great difference in working temperature. Furthermore, it can be used in a wide range of area. It also can represent a good economy when in a situation of implement apex- vale electrovalence. As a result this new device has a high value for application.
