Embodiment Construction

[0013] Such as figure 1 The shown movable sunshade system in the outer window of the building consists of an outer sash frame 1 and an inner and outer double-layer insulating glass installed on the outer sash frame, a movable sunshade 4 placed between the double-layer insulating glass, and a control system The control device of the movable sunshade consists of.

[0014] 1. Reflective treatment on the outer side of the sunshade:

[0015] The present invention introduces the requirement of improving the reflectivity of sunlight for the central sunshade system, adopts mirror reflection or brushing reflective heat-insulating coating technology to form a reflective heat-insulating coating on the outer surface of the metal venetian blind of the central sunshade system. The outer surfaces of the system's fabric folding curtains, honeycomb blinds, and roller blinds are painted with reflective aluminum-silver paste paint to improve the reflectivity of the outer surface of the sunshade...

Abstract

At present, a sun-shading curtain radiates heat which is more than that obtained by an external sun-shading system under sunlight radiation and is close to that obtained by an internal sun-shading system when being used in a centrally-mounted sun-shading system, and the centrally-mounted sun-shading system has a poor insulation energy-saving effect. The invention provides a centrally-mounted movable sun-shading system of a building external window with low heat gain efficiency under sunlight radiation. The centrally-mounted movable sun-shading system comprises an external window frame, an inner hollow glass layer and an outer hollow glass layer which are installed on the external window frame, a movable sun-shading curtain arranged between the inner hollow glass layer and the outer hollowglass layer, and a control device of the movable sun-shading curtain. The centrally-mounted movable sun-shading system is characterized in that a mirror surface or reflection heat insulation coating is formed on the surface of the outer side of the movable sun-shading curtain; and an upper ventilating pipe and a lower ventilating pipe are respectively embedded in upper sealant and lower sealant which are arranged between the inner hollow glass layer and the outer hollow glass layer. According to the invention, the heat insulation effect is effectively improved, and the purpose of reducing indoor solar radiation heat through an external window and further reducing refrigeration energy consumption of an air conditioner in a building in summer is achieved.

Description

technical field [0001] The invention relates to a central movable sunshade system, in particular to a central movable sunshade system for building exterior windows in which the sunshade between the double-layer hollow glass has the function of reflecting sunlight radiation and the interlayer between the double-layer hollow glass can be ventilated. Background technique [0002] In regions with hot summer and cold winter in China (including regions with hot summer and warm winter), building energy consumption is very high due to solar radiation in summer, and it continues to increase with climate warming. In regions with hot summer and cold winter, the energy consumption of air conditioning and cooling in summer is about the same as that of heating in winter It is more than twice that, mainly due to the rising temperature in summer and the heating of the building envelope by sunlight, especially the east, south and west windows of the building exposed to direct sunlight. There...
