The operating mode of the SPHP system The solar phase change heat storage evaporative heat pump system is a composite system that uses a phase change heat storage system as its center and is coupled with a solar system and a heat pump system to supply heat.
It is recognized that a phase change thermal storage material is the best choice to solve the problem of solar energy utilization. However, in the literature on solar heat pump systems, the sensible heat storage of water is still used, and no phase change heat storage material suitable for the solar heat utilization interval has been used.
In this study, a phase-change heat storage solar heating system is proposed for a farmhouse, and four operating modes of the heating system are constructed based on the solar energy production capacity, heating load characteristics, and local electricity price model.
In solar heating systems, the ideal phase-change material needs to have the advantages of high latent heat, high density, high thermal conductivity, stable performance, good compatibility with the container and low price. Paraffin is an organic phase-change material with moderate price and good heat storage performance.
This is because the phase change heat storage material in the phase change heat storage tank continuously supplies heat to the system heat pump. It can be seen that the difference between the heating energy consumption by the SPHP and by the separate heat pump system is the amount of solar energy stored during the day.
Conclusions A phase-change thermal storage solar heating system is proposed for rural areas in northern China. The system was applied to a farmhouse in Tianjin, and its practical application effect was tested under four operating modes.
