摘　　要：介绍了相变材料在太阳能热泵系统中的应用现状,开发适用于太阳能热泵系统的脂肪酸类相变材料。以某太阳能空气源热泵系统为研究对象,在蓄热水箱中安装相变蓄热装置,满足夜间值班供暖热负荷。与安装相变蓄热装置前比较,系统的动态费用年值下降,经济性提高。The application status of phase-change materials in solar heat pump system is intro- duced to develop fatty acids-like phase-change materials suitable for solar heat pump system. Taking a solar air-source heat pump system as research object, a phase-change heat storage device is installed in the heat storage water tank to meet heating heat load during night watch. Compared with before installing the phase-change heat storage device, the dynamic annual cost of system is reduced, and the economic efficiency is improved.
