摘　　要： 对以CaCl2.6H2O为相变材料的太阳热泵蓄热系统,采用焓法建立了以相变材料封装容器为控制体单元的相变传热模型,计算了蓄热水箱进出口温度,相变材料温度及水箱蓄、放热量等参数。通过对实验结果与模拟结果的比较分析可知,两者数据接近,变化趋势吻合,该模拟方法能较好地反映系统运行情况。 The rectangular phase change storage tank （PCST） linked to a solar aided heat pump （SAHP） system was investigated. A heat transfer model of the container of phase change material （PCM） was developed. It was solved numerically by an enthalpy-based finite differences method and validated against experimental data. Cal2·6H2O was used as the PCM in the latent heat storage system of SAHP. Inlet and outlet water temperature of PCST, temperature of PCM and storage and emission heat of PCST were calculated. The comparison of numerical results and experimental data should the data and the varying trend had a close agreement, and numerical results can reflect the operation mode of the system very well.
