Ceramic solar modular phase change heat storage sunlight greenhouse and phase change solution thereof

Abstract

The invention discloses a ceramic solar modular phase change heat storage sunlight greenhouse and a phase change solution thereof. A rear greenhouse wall comprises a heat preservation thermal insulating component, a rear greenhouse wall steel structure component and a solar ceramic phase change component, wherein the solar ceramic phase change component comprises a ceramic solar panel and a ceramic solar panel water returning pipeline; the heat preservation thermal insulating component, the rear greenhouse wall steel structure component and the ceramic solar panel form a rear greenhouse wall body structure; the ceramic solar panel water returning pipeline communicates with the inner cavity of the ceramic solar panel and is arranged inside the rear greenhouse wall steel structure component; the ceramic solar panel water returning pipeline is filled with the phase change solution. The ceramic solar modular phase change heat storage sunlight greenhouse can be rapidly manufactured and assembled in a modular manner, meanwhile heat can be stored and released actively by using a fan assembled on the rear greenhouse wall, and furthermore heat can be directly acquired from sunshine by using a liquid phase change material inside the rear greenhouse wall.

Description

technical field [0001] The invention belongs to the field of phase change materials and applications thereof, and in particular relates to a ceramic solar modular phase change thermal storage solar greenhouse and a phase change solution thereof. Background technique [0002] At present, the back walls of conventional solar greenhouses mostly adopt brick back walls and piled earth back walls. Among them, the performance of the brick back wall is excellent, but the cost is high, so it is not suitable for popularization in remote areas; in contrast, although the earth-pile back wall greenhouse is cheap and easy to obtain materials, the structure is easy to collapse, and there are also some The defects of short service life and poor production conditions, and because mechanical excavation is often used in construction, the destructive power to the original land is very strong, and the land utilization rate is low even after completion. In addition, with the large-scale promotio...

AI Technical Summary

Problems solved by technology

[0003] In addition, in terms of heat storage in solar greenhouses, most conventional solar greenhouses use passive heat storage, and because the heat storage bodies are mostly masonry and soil, the heat storage density is relatively small, resulting in a serious shortage of heat storage in the greenhouse.

Moreover, in production practice, in order to expand the heat storage performance of the back wall of the greenhouse, the thickness of the back wall can only be thickened continuously, thus resulting in an increase in the area occupied by the greenhouse and an increase in the cost of civil engineering

The survey found that for the heat storage of the solar greenhouse, the back wall was built thicker and thicker, and the cost gradually increased, but at the same time, the heat storage performance of the greenhouse did not improve much
