Abstract

The invention relates to a glass window sunshade device, and particularly discloses a heat preservation type sunshade and energy-saving device. The device comprises a hollow glass body, multiple louvers which are arranged in parallel, and a drive device for driving the louvers to rotate; the internal part of the hollow glass body is formed into a closed cavity; the louvers are installed in the closed cavity; a high absorption rate coating and a high reflectance coating are respectively arranged at the front surface and the back surface of each louver; and a low reflectance plating film is arranged on the cavity wall at one side of the closed cavity facing to outside. According to the device provided by the invention, the high absorption rate coating is combined with the low reflectance plating film, the long wave radiation produced by the louvers and the indoor long wave radiation are reflected to indoor through the low reflectance plating film, thus, the louvers and indoor heat are prevented from losing outwards through the long wave radiation, and a better heat preservation effect can be played.

Description

technical field

[0001] The invention relates to a sunshade device for glass windows, in particular to a heat preservation type sunshade energy-saving device. Background technique

[0002] Buildings are exposed to different outdoor weather conditions throughout the year, usually hot in summer and cold in winter. However, people hope that the indoor temperature can be warm in winter and cool in summer. If you rely entirely on air-conditioning or heating systems, it will consume a lot of energy. Therefore, it is very necessary to construct energy-saving buildings, and the shading system plays a vital role in existing energy-saving buildings.

[0003] Now the mainstream shading system is mainly divided into external shading system, internal shading system and breathing curtain wall shading system. These three shading systems each have their pros and cons:

[0004] Among them, the external shading system is a better solution from the thermal point of view, completely shielding...
