摘要：

By using phase change heat storage technology in solar heat pumps, it is possible to upgrade the performance coefficient of heat pumps, alleviate the inconvenience caused by solar instability, and increase the efficiency with which solar energy is utilized. And provide a solution to the mismatch between time and space and low-grade energy. This article integrates solar heat pump systems and phase change heat storage technology. Related technologies and research are outlined from the three perspectives of solar heat pump heating, defrosting, and energy conservation, along with the most recent developments in the use of phase change materials. During the discussion, some pressing issues regarding the use of phase change heat storage technology in solar heat pumps were raised. The multi-energy coupled heat storage solar heat pump is the future research direction of the application of phase change heat storage technology in the solar heat pump. It is pointed out that the future development trend is to improve the thermal conductivity of phase change materials, optimize the structure, and strengthen the heat transfer.
