How to make solar energy phase change combined heat pump heating system play the greatest role?

The utility model relates to a solar energy phase change storage combined heat pump heating system, which comprises a power generation and network connection unit of the photovoltaics, an air source heat pump, a phase change energy storage and temperature regulating unit and a heating terminal, the photovoltaics is powered by an air source heat pump, which generates heat through the operation of the air source heat pump. The water is used as the heat medium and the phase change energy storage unit is used for constant temperature regulation to provide a steady heat supply to the heating end. Through the above ways, the solar energy phase change storage heat pump heating system of the utility model combines the phase change energy storage technology with the solar energy, and converts the Solar Energy into electricity to drive the heat pump to generate heat through a photovoltaic power generation system, using phase change energy storage can adjust heat flux density under constant temperature, improve energy efficiency and energy efficiency, solve the intermittent problem of solar energy, and realize all-weather solar heating.
