[0002] Phase change heat storage is an electric heater that uses phase change material as the heat storage medium. Phase change heat storage is a high-tech energy storage technology based on phase change energy storage materials. It is mainly divided into thermochemical heat storage, sensible heat storage and phase change heat storage. Due to its advantages of constant temperature and high heat storage density, phase change heat storage technology has been widely studied and is particularly suitable for working conditions where heat supply is discontinuous or supply and demand are not coordinated.

[0003] During use, existing phase change heat storage equipment mostly uses phase change heat storage materials to be encapsulated in phase change heat storage balls of a certain shape, and then the heat storage balls are placed in a heat storage tank. Subsequently, a heat carrier fluid of equal density is injected into the heat storage tank, and the external heating water is heated by an external heater. The heating water heats the heat carrier fluid through a heat exchanger. Under the action of a circulating pump, the heat carrier fluid returns to the heat storage tank to heat the phase change heat storage balls and stores the heat in the phase change heat storage balls. When in use, the heat carrier fluid takes heat from the phase change heat storage balls, and then the circulating pump draws the heat carrier fluid from the heat storage tank and injects it into the heat exchanger. The heating water is then heated by the heat exchanger and returned to the heat storage tank.
