Problems solved by technology

[0004] In the process of heat storage and heat release, there must be efficiency loss
Especially in the later stage of the heat storage process, after the heat storage medium increases to a certain extent, and in the later stage of the heat release process, after the heat storage medium decreases to a certain extent, the heat transfer efficiency decreases, and the heat storage device Part of the heat cannot be exchanged and utilized, resulting in low overall utilization efficiency

Abstract

The invention discloses a combined type phase-change heat storage device, which comprises a heat storage tank, a sensible heat storage material, phase-change heat storage media and a phase-change heat storage media package, wherein the phase-change heat storage media are sealed in the phase-change heat storage media package and act together with the sensible heat storage material to realize a heat storage or release process.

Description

technical field [0001] The invention belongs to the technical field of phase change heat storage and sensible heat storage, and discloses a combined phase change heat storage device. Background technique [0002] In many fields of energy utilization such as solar heat utilization, industrial waste heat recovery, heating and air conditioning, in order to adjust the inconsistency between heat supply and actual demand, heat storage is an extremely critical link. [0003] There are two types of heat storage methods commonly used at present: 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 la...
