Abstract

The invention belongs to the technical field of phase change material energy storage, and in particular, relates to a normal-pressure phase change heat storage device. The device comprises main waterinlet and water outlet pipes connected with a circulating system, and heat supply water inlet and water outlet pipes and heat storage water inlet and water outlet pipes placed in a liner and connectedwith the main water inlet and water outlet pipes; and water distribution holes are mechanically formed in the water inlet and water outlet pipes in the device in proportion. A heat supply electric two-way valve communicating with the heat supply water outlet pipe and a heat storage electric two-way valve communicating with the heat storage water outlet pipe are additionally mounted out of an outer shell; multiple layers of separation plates are arranged in the liner; energy storage balls are placed in the separation plates; and the liner is provided with a water feeding port, a water overflowing port, a dirt discharge port, a liquid level sensor and a maintenance port communicating with the outer shell and an insulation material. The device has the advantages of reliable structure, stableheat outputting, high heat efficiency, simple installation, high heat exchange efficiency and high unit volume heat storage quantity.

Description

technical field [0001] The invention belongs to the technical field of phase change material energy storage, and in particular relates to an atmospheric pressure phase change heat storage device. Background technique [0002] There are two types of commonly used heat storage methods, namely, sensible heat storage and latent heat storage. Sensible heat storage is mainly to store heat energy through the rise or fall of the temperature of a certain material. Sensible heat storage is the one with the simplest principle, the most mature technology, the most abundant material sources and the cheapest cost among various heat storage methods. Therefore, it is also the most widely used and promoted in practice. The basic principle of latent heat storage is that when a substance changes from a solid state to a liquid state (melting), from a liquid state to a gaseous state (gasification), or directly from a solid state to a gaseous state (sublimation), it will absorb phase change heat...
