The present disclosure discloses a heating system coupling a passive phase change energy storage sunlight room with an air source heat pump. The heating system includes a passive phase change energy storage sunlight room (), phase change heat storage units, a to-be-heated room (), and an air source heat pump air heater arranged between the passive phase change energy storage sunlight room () and the to-be-heated room (), wherein each phase change heat storage unit () consists of a plurality of phase change heat storage modules (). An opening in the front part of each phase change heat storage module faces an interior of the passive phase change energy storage sunlight room, and the phase change heat storage modules located on the top are spliced transversely, and the vent in the top of each phase change heat storage module is connected with the ventilation port of the room.

Heat supply system coupling passive phase change energy storage sunlight room and air source heat pump

A solar phase-change energy storage heating ventilation partition wall and modular heating system thereof, the partition wall consists of a solid partition wall (), a thermal insulation layer (), a decoration layer (), frame of steel reinforcement (), reflecting layers () and phase-change heat storage modules (), the modular heating system comprises a solar air collector (), phase-change heat storage units () arranged modularly, and a partition wall, to achieve energy storage and heating. Compared with the prior art, the modular heat storage partition wall components are simple in manufacturing process and flexible in assembly, and can be freely arranged and combined according to actual conditions; the system collects solar energy by the solar air collector during the daytime and stores the heat in the phase-change heat storage modules in the partition wall; and the heat storage partition wall can provide heat for the room in a radiation manner.
