Multifunctional solar heat collection wall based on photo-catalytic oxidation technique

Abstract

The invention discloses a multifunctional solar heat collection wall based on a photo-catalytic oxidation technique. The multifunctional solar heat collection wall is arranged in a concave wall and positioned between a ground and a roof, and comprises a high light permeability glass plate, a solar photovoltaic cell panel, a phase-change heat storage body, a thermal insulating wall and a photocatalyst film, wherein the photocatalyst film is carried on the inner side of the high light permeability glass plate; an air channel is formed between the photocatalyst film and the solar photovoltaic cell panel; the phase-change heat storage body and the thermal insulating wall are sequentially connected to the inner side of the solar photovoltaic cell panel. The invention provides the multifunctional solar heat collection wall based on the photo-catalytic oxidation technique, the wall has multiple functions such as heat collection, air ventilation, air purification, power generation and heat storage, compared with a conventional solar building integral heat accumulation wall, the wall is capable of achieving the purpose of efficiently utilizing solar energy at multiple stages, moreover, in the whole process, other energy except the solar energy is not used, and requirements of energy conservation and emission reduction and green buildings can be met.

Description

Problems solved by technology

But at present, the main problem of Trombe wall is that due to the instability of solar radiation, its use effect is not good at night or on cloudy days; at the same time, the function of traditional Trombe wall is relatively single, and it cannot achieve the purpose of using solar energy resources more effectively

At present, some people have proposed a Trombe wall structure integrating photovoltaic power generation and heating, that is, direct external, central, and built-in solar photovoltaic panels in the Trombe wall, but these methods all have uneven temperature distribution on the photovoltaic panel, which affects other Issues of Service Life and Photovoltaic Power Generation Efficiency
