Photovoltaic phase change wall system and implementation method thereof

Abstract

The invention provides a photovoltaic phase change wall system and an implementation method of the photovoltaic phase change wall system. A photovoltaic panel is attached to the outer wall of a phase change wall, solar energy absorbed by the photovoltaic panel is converted into electric energy and stored in a storage battery connected with the photovoltaic panel, the stored electric energy can be used for forced ventilation at night in a hot summer and warm winter zone to promote the phase change wall to release heat to achieve phase change cycle, and therefore the problems that in the prior art, the efficiency of the photovoltaic panel for converting light energy into electric energy is low due to the fact that the temperature of the surface of the photovoltaic panel rises, and temperature adjusting capacity of the phase change wall is low due to insufficient phase change cycle are solved. By the adoption of the photovoltaic phase change wall system and the implementation method of the photovoltaic phase change wall system, solar energy can be efficiently utilized, phase change cycle of the phase change wall is promoted, the temperature of the photovoltaic phase change wall can be efficiently adjusted in an energy-saving mode, and an appropriate heat comfortable environment is provided for indoor space of a building under the condition of low or even zero energy consumption.

Description

technical field [0001] The invention relates to the application field of solar power generation, in particular to a photovoltaic phase-change wall system and its realization method. Background technique [0002] Solar energy is abundant in resources, which can be used for free, without transportation, and without any pollution to the environment. Solar photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. The use of solar photovoltaic materials to replace traditional building materials can make the building itself a large energy source, achieving energy saving and environmental protection effects. At present, the main factors limiting solar photovoltaic power generation are the low power generation efficiency of solar photovoltaic panels and the high cost of solar power generation. Under standard conditions, the conversion efficiency of silicon cells is about 12%-17%, bu...
