摘　　要：本文通过三套管蓄能换热器(其内管为制冷剂,中间为相变蓄能材料,外管为水)将夏季蓄冷与冬季蓄热有机结合在一起,克服了太阳能的间歇性和不稳定性,组成了三套管蓄能型多热源热泵集成系统。而后,阐述了该系统的结构及特征,对比分析了冰蓄冷系统与高温相变蓄冷系统的能耗情况。结果表明,当室外温度为15～30℃时,高温蓄冷系统的COP较冰蓄冷系统高40%～78%,制冷量有所提高,耗功有所降低,具有显著的节能潜力。In this paper,a heat pump integrated system with triple-sleeve energy storage exchangers was introduced.With the triple-sleeve energy storage exchangers（the inner tube media was refrigerant,in the middle was the energy storage material and the outer tube media was water）,the combination of cold storage in summer and hot storage in winter was realized.This system overcame the disadvantages of solar energy,such as intermittence and instability.And then,the structure and characteristics of the system was described,and the energy consumption of ice storage system and high temperature phase change storage system was compared and analyzed.The results indicated that COP of high temperature phase change storage system was 40% ～ 78% higher than the ice storage system when the outdoor air temperature was 15 ～ 30 ℃.In other words,the cooling capacity of the high temperature phase change storage system was improved and the energy consumption was reduced,its energy-saving potential was significant.
