Description

Assembled solar heat accumulator mounting structure independently arranged in greenhouse

Technical Field

The utility model belongs to the technical field of greenhouses, and particularly relates to an assembled solar heat accumulator mounting structure independently arranged in a greenhouse.

Background

In the prior art, no matter brick wall, earth wall or other heat storage and insulation wall, heat storage materials are mixed, embedded and overlapped into the wall (namely, mixed, filled and externally hung) for heat storage, or the heat storage materials are used for direct heat storage. The heat storage material is used for heat collection, heat storage and heat dissipation, and also participates in heat preservation and heat insulation and structure bearing work. Thus, there are the following common disadvantages: 1. the thermal insulation material needs lower heat conductivity coefficient so that the wall body has higher thermal resistance value; the heat storage material and its packaging material require a higher thermal conductivity to improve the heat exchange efficiency. Therefore, the constructional measures of mixing, embedding and stacking the heat storage material into the wall are contradictory. 2. The heat storage material mixed, embedded and overlapped on the wall body is in a heat dissipation state in reality, namely the heating area and the indoor heat dissipation area are reduced; can not be fully utilized for heat exchange by three heat transfer modes; the thermal conductivity is reduced by the enclosing walls of the thermal storage material and the surrounding building material. Therefore, the heat collection, heat storage and heat dissipation (indoor heat dissipation) efficiency is low, the heat loss is large, and the solar energy utilization rate is low. 3. Limiting the range of options for the thermal storage material. 4. Limiting the choice of shapes and materials of the packaging container. 5. Most phase change heat storage materials have the defects of volatilization and aging, and are difficult to supplement, maintain and replace after being mixed into the structure. 6. The active heat exchange equipment and the pipeline thereof need to run for a long time, and the pipeline is difficult to overhaul and replace.

The construction method for mixing, embedding and superposing the heat storage material on the wall body increases the complexity and ambiguity of the design and calculation of the heat insulation performance, the heat storage performance and the bearing capacity of the component due to the fact that the heat insulation material needs lower heat conduction coefficient, the heat storage material and the packaging material thereof need higher heat conduction coefficient, the expansibility and corrosiveness of the heat storage material and the like.
