Multifunctional photovoltaic shutter energy-saving window

Abstract

The invention discloses a multifunctional photovoltaic shutter energy-saving window which comprises outer glass, an air cavity, a multifunctional shutter assembly, inner glass, a window frame and an adjusting device. The outer glass and the inner glass are fixed on the window frame in parallel; the air cavity is positioned between the outer glass and the inner glass; the multifunctional shutter assembly is arranged in the air cavity; the multifunctional shutter assembly comprises shutters and a rotating shaft. The shutters are fixed on the rotating shaft and can rotate around the rotating shaft; and each shutter is composed of a blade A, a blade B, a blade C, a blade D which are sequentially arranged at an included angle of 90 degrees and a connecting device. Air flow resistance in the air cavity is increased through the multifunctional shutter assembly, natural convective heat transfer between the outer glass and the inner glass is effectively weakened, and the heat preservation and insulation performance of the window is improved; meanwhile, the functions of sun shading in summer, heating in winter, glare prevention, power generation and the like are achieved by adjusting the rotating angle of the multifunctional shutter assembly, the collaborative reduction of building cooling and heating loads and lighting loads is facilitated, and building energy saving is promoted.

Description

technical field [0001] The invention belongs to the technical field of building doors and windows, and in particular relates to a multifunctional energy-saving photovoltaic louver that integrates the functions of sunshade in summer, heat gain in winter, anti-glare and power generation. Background technique [0002] Windows play an important role in providing natural lighting to meet people's visual needs in the building, but they are also the weak link in the thermal insulation of the building envelope, which restricts the improvement of building energy efficiency. The existing window technology mostly adopts the structural design of double-layer or multi-layer glass, and the heat transfer resistance of the window is increased by increasing the air layer, which improves the thermal insulation performance of the window to a certain extent. In addition, in order to reduce the heat gain of solar radiation through the windows in summer and reduce the probability of glare, techno...

Problems solved by technology

In addition, in order to reduce the heat gain of solar radiation through the windows in summer and reduce the probability of glare, technologies such as window shading or low-emissivity glass are often used, but this will reduce the heat gain of the building in winter and cause an increase in heat load. Therefore, building windows There is a problem that it is difficult to balance the sunshade in summer and the heat gain in winter

[0003] Although the existing window technology can reflect or absorb solar radiation according to needs, it does not take into account the lighting performance of the window, and cannot solve the problem of the obvious increase in solar radiation heat gain caused by window lighting in summer

In addition, the thermal insulation performance of windows still needs to be further improved
