摘　　要：提出一种新型集热/蓄能/蒸发一体化太阳能热泵热水器,搭建实验测试装置,对蓄能材料分别为水、癸酸、石蜡时的太阳能集热/蓄能/蒸发器的蓄能特性和集热总效率进行研究,并在南京地区春季典型工况下,对蓄能材料为癸酸和石蜡的SHPWHICSE系统性能系数进行研究对比。研究结果表明:相变材料比水有更好的集热效果;由于石蜡的比热容大,其集热总效率大于癸酸,采用石蜡的SHPWHICSE系统性能在各种实验条件下均高于采用癸酸的SHPWHICSE系统。A new solar heat pump water heater integrated with collector, storage and evaporation was presented. The experimental device was set up. This paper researched the storage characteristic and overall collection efficiency of the collector using water, decanoate and paraffin, respectively. Comparative study of the system＇ s coefficient of performance was done when using decanoate and paraffin as PCMs under spring typical operating conditions in Nanjing. The results indicated that PCMs have better collector effects than water. The overall collection efficiency of the paraffin is higher than that of the decanoate, because the paraffin has higher specific heat. Moreover, the coefficients of performance of the SHPWHICSE using paraffin are higher than using decanoate＇ s under all kinds of experimental conditions
