本文介绍了一种新型的太阳能辅助热泵系统与相变储能，并描述了所提出的系统的性能分析方法。建立了系统关键部件太阳能蒸发器、冷凝器、相变储能罐、压缩机的数学模型。在平行的建模工作，实验装置的建议太阳能存储热泵系统的开发。实验数据表明，所设计的系统能够满足吉林省延边市农村地区的冷日供暖需求。在白天运行时，太阳能热泵系统将多余的能量储存在能量储存箱中用于加热目的。室内温度达到了预期的要求，太阳能热泵的平均性能系数为4.5，系统全天运行稳定。在夜间操作中，存储在存储罐中的能量通过所采用的相变材料中的液-固相变释放。通过这种方式，确保了建筑物内10小时的连续供热，并实现了所需的室内空气条件。
This paper introduces a novel solar-assisted heat pump system with phase change energy storage and describes the methodology used to analyze the performance of the proposed system. A mathematical model was established for the key parts of the system including solar evaporator, condenser, phase change energy storage tank, and compressor. In parallel to the modelling work, an experimental set-up of the proposed solar energy storage heat pump system was developed. The experimental data showed that the designed system is capable of meeting cold day heating demands in rural areas of Yanbian city located in Jilin province of China. In day-time operation, the solar heat pump system stores excess energy in the energy storage tank for heating purposes. A desired indoor temperature was achieved; the average coefficient of performance of solar heat pump was identified as 4.5, and the system showed a stable performance throughout the day. In night-time operation, the energy stored in the storage tank was released through a liquid-solid change of phase in the employed phase-change material. In this way, the provision of continuous heat for ten hours was ensured within the building, and the desired indoor air conditions were achieved.
