Problems solved by technology

[0004] 1. The structure of the existing heat storage device is fixed, and maintenance is difficult. There is no modular assembly setting for matching the supply and demand of different users, and the effective expansion is insufficient, which affects its popularization and application
[0005] 2. The coordinated control of heat storage and release of the system is not good, and there is a lack of effective monitoring and coordinated control between the heat source, heat storage and release unit and the user, and it is easy to cause heat loss in the heat storage unit due to the low temperature of the heat source in the heat storage working condition
[0006] 3. The user’s heat guarantee rate is insufficient, renewable energy, waste heat, etc. generally have low energy flow density, and the heat production fluctuates greatly due to the influence of environmental conditions. The released heat cannot meet the user's heat demand, which affects the use effect

Embodiment 1

[0037] An assembled heat storage and release module, such as figure 1 As shown, it includes a heat storage and release unit 2 and a fabricated shell 1, such as Figure 4-6As shown, the heat storage and release unit 2 includes a cylindrical inner shell 24 and an outer shell 25, the space between the inner shell 24 and the outer shell 25 serves as a fluid channel 26, and the top of the fluid channel 26 is symmetrically provided with two fluid inlets / inlets 21 , used to connect the supply / return piping. The cavity within the inner shell 24 is filled with a phase change material 29 . A number of inner wall fins 27 are evenly distributed on the inner wall of the inner shell 24 in the longitudinal direction, and a number of outer wall fins 28 are evenly distributed in the longitudinal direction on the outer wall of the inner shell 24 to enhance the heat exchange efficiency between the fluid and the phase change material. The top of the heat storage and release unit 2 is provided w...

Embodiment 2

[0041] like Figure 7-8 As shown, the assembled casing 1 in this embodiment includes an assembly plate 12 and a columnar connecting piece 11 , and the assembly plate 12 and the connecting piece 11 have the same height and the same height as the heat storage and release unit housing. The left and right ends of the assembly plate 12 are provided with T-shaped second ridge-shaped guide rails 16, and the two sides of the middle of the assembly plate 12 are provided with rectangular third groove-shaped guide rails 13. The position and size of the third groove-shaped guide rails 13 should be consistent with the heat storage and discharge. The third ridged rail 23 on the unit housing corresponds. The connecting member 11 is provided with four inverted T-shaped second groove-shaped guide rails 17 diagonally, and the shape and size of the second ridge-shaped guide rails 16 and the second groove-shaped guide rails 17 are matched. The structure of the heat storage and release unit and t...

Abstract

The invention relates to the technical field of phase change energy storage, in particular to an assembly type heat storage and release module and an intelligent control phase change heat storage and release system. The assembly type heat storage and release module comprises a heat storage and release unit, the heat storage and release unit is sleeved with an assembly type shell, the assembly type shell comprises an assembly plate and a connecting piece, and the assembly plate and the connecting piece are assembled into the shell used for containing the heat storage and release unit through a first guide rail structure. The connecting piece is provided with a connecting structure used for connecting the adjacent heat storage and release module assembling plates. A plurality of groups of heat storage and release modules, an intelligent controller, temperature sensors and control valves form an intelligent control heat storage and release system. The system disclosed by the invention is high in structural flexibility, and the expansibility, the regulation and the collaboration are enhanced. According to the heat storage and release part, the number of the used heat storage and release modules and the adjusting method can be adjusted according to the matched low-grade heat source system and the served heat users so as to adapt to different use environments, and the overall energy utilization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of phase change energy storage, in particular to an assembled heat storage and release module and an intelligent control phase change heat storage and release system. Background technique [0002] Improving energy utilization is the key to optimizing energy consumption structure and solving the problem of energy shortage. However, most renewable energy sources such as solar energy and wind energy have intermittent and decentralized characteristics. It is difficult to effectively recover and utilize waste heat in industrial production, resulting in energy waste. Seriously, the development of energy storage technology is an important link in balancing energy supply and energy consumption. The phase change energy storage technology achieves the purpose of energy storage by absorbing or releasing a large amount of heat during the phase change of the phase change material. It has the characteristics of high energ...
