Embodiment Construction

[0013] figure 1 Among them, the window frame 3 of the window 2 of the facade 1 is connected with two winding drums 5 and 6 that are connected to the inner edge of the rollable covering 4 and can be rolled and unfolded; the outer edge of the covering 4 is connected Pull rod 7, and pull rod 7 is connected with drag cable 8. The indoor side of window 2 is provided with two manual chain ropes 9 (only showing one among the figures) that are connected with winding drum 5 and 6 respectively. Pull the manual chain rope 9 to move the cover 4 so that the bonding line on it is bonded to the glass 10, and the cover 5 and the glass 10, that is, the light-receiving surface of the building, form a seamed closed space 11 together. The closed space 11 with seams communicates with the negative pressure source through the exhaust channel shown by the dotted line, so that the cover 4 is sucked onto the glass 10 .

Abstract

The invention provides a method for sun screening, heat shielding and cooling of negative pressure adsorption coverings. The method comprises the following steps that: the coverings are arranged on the surface of articles including roofing, facades, or the indoor side of the facade glass and the inside of double-layer glass, and are adsorbed on the surface of the article for sun screening, heat shielding and cooling. The device for sun screening, heat shielding and cooling of negative pressure adsorption coverings, which is prepared by the method, consists of a covering and a negative pressure source, and is characterized in that an exhaust passage is arranged between a closed space formed between the surface of the article and the covering and the negative pressure source. The device has the advantages of convenient negative pressure adsorption operation of the coverings, little noise, good sun screening, heat shielding and cooling effects, and wide adaptability; the coverings with selective spectral characteristics can reduce indoor ultraviolet rays and heat energy and provide natural lighting and enjoyment of wide vision of glass curtain wall; and under a light intensity of 600w / m<2>, when the coverings are used for the single-layer glass, the indoor heat energy can be reduced by 6.9 times or 505.5w / m<2>. Two embodiments are shown with the figures.

Description

Technical field [0001] The invention relates to a method and a device for heat-cooling a sun-proof screen of a cover with negative pressure suction. Background technique [0002] The curtain wall glass building is magnificent and has a wide view, but the heat transfer coefficient of single-layer glass is 6.21w / (m 2 ℃), the specific energy-saving wall is 0.35~0.5w / (m 2 °C) is much larger, and the heat of sunlight entering the room in summer can reach 600w / m 2 resulting in a substantial increase in cooling load. In order to reduce the sunlight entering in summer, the glass can be painted, filmed and single-silver or double-silver reflective glass can be used. However, these methods are not ideal for heat resistance, and also affect winter lighting and visual effects. In addition, the non-curtain wall glass walls of many existing structures and the surfaces of other objects also have the need for sun protection and thermal cooling.
