摘　　要：本文提出了1种新型蓄能型一体化太阳能热泵热水器系统(SHPWHICSE),搭建了实验测试装置。在南京地区春季典型工况下,对集热/蓄能/蒸发一体化太阳能热泵热水器系统充灌蓄能材料石蜡前后的蓄能特性进行了实验研究。结果表明:充灌相变材料石蜡后,相变材料通过固-液相变储存足够的太阳能,SHPWHICSE系统可保证在1天中任意时刻启动。采用石蜡为蓄能介质的一体化太阳能热泵热水器系统的COP和得热效率均高于未充灌相变材料的系统。太阳辐射强度的不稳定波动对采用石蜡为蓄能介质的一体化太阳能热泵热水器系统得热效率的影响比其对未充灌相变材料的太阳能热泵热水器系统的影响小。This paper proposes one kind of new energy storage type integrated solar heat pump water heater system （SHPWHICSE） , and sets up an experimental testing device. This paper conducts an experimental study under the typical operating conditions in the spring in Nanjing on the energy storage characteristics of storage collection/ energy storage/evaporation integrated solar heat pump water heater system before and after the energy storage material-paraffin is filled. The results show that： After phase change material-paraffin is filled, the phase change material stores adequate solar energy by solid-liquid phase change, and SHPWHICSE system can be started at any time within 1 day. COP and thermal efficiency of integrated solar heat pump water heater with paraffin as an energy storage medium are higher than those of the system not filled with phase change material. Unstable fluctuations of solar radiation intensity has less impact on thermal efficiency of integrated solar heat pump water heater system with paraffin as an energy storage medium than the solar heat pump water heater system not filled with phase change material.
