AB - In order to understand the solar heat pump heating system, a phase-change  storage solar heat pump heating system based on cloud computing is  proposed. This paper first introduces the solar heat pump as a phase change  energy storage that can change four types of heat depending on the weather  conditions and significantly reduce the energy consumption of the system.  Second, through the special design of the energy storage capacitor, in  addition adjusting the energy distribution of the solar heat pump system, it  can also improve the reliability of supply and demand between the solar heat  pump system and the building heating system, improve the level of solar  energy consumption, but also improve the low temperature of the pump milk  temperature, and improve the solar heat up quickly to achieve the goal of  improving the overall performance of the heat pump. Finally, this paper  takes an urban "electric coal" house as a research object to investigate the  hot air efficiency of solar heat pumps. This paper analyzes the daytime  solar heat pump mode, the nighttime energy storage mode under extreme  conditions, and the air source heat pump mode. And shows the research  results that the solar heat pump has good heating efficiency and the highest  solar COP. Will be heat pump is 5.28 solar energy average heat pump COP is  2.13. In very bad weather, solar heat pumps work better.
