Problems solved by technology

However, in places with poor outdoor air quality, there is a risk of bringing outdoor pollutants into the room. Natural ventilation is sometimes restricted due to environmental noise pollution. The cooling effect of windows or vents is affected by the difference in indoor and outdoor temperature and the structure. Influenced by the shape, it cannot cool down continuously for 24 hours

Abstract

The invention discloses a hollow radiation-cooling passive type structure for a building external wall or a roof. The hollow radiation-cooling passive type structure comprises an air cavity which consists of an outer-layer plate, an inner-layer plate, an upper top plate, a lower bottom plate and two side plates, wherein the upper top plate and the lower bottom plate are fixedly arranged at upper and lower ends of the outer-layer plate separately; the two side plates are fixedly arranged at the two sides of the outer-layer plate separately; the two side plates are connected with the upper top plate, the lower bottom plate and the inner-layer plate; an air inlet is formed between the inner-layer plate and the upper top plate; an air outlet is formed between the inner-layer plate and the lower bottom plate; the air inlet and the air outlet are separately formed in upper and lower positions of the inner-layer plate to communicate an indoor space and an air cavity; and a radiation cooling metamaterial layer is arranged on the outer side surface of the outer-layer plate. According to the technical scheme adopted by the invention, natural exchange between the structure and indoor air is realized in case of not consuming energy, so that the cooling effect is achieved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a hollow radiation cooling passive structure for building exterior walls or roofs. Background technique [0002] In the prior art, common building ventilation structures mainly include Tromble wall and double-layer glass curtain wall, but the function of Tromble wall is to use solar energy for heating; the main function of double-layer glass curtain wall is heat insulation and sound insulation, and its ventilation function is mainly It uses natural outside air to cool the air inside the curtain wall to prevent heat from entering the room due to overheating in summer. So it is not really a structure that can cool the indoor air. [0003] Only natural ventilation windows or openings can really cool the indoor air in a passive way. However, in places with poor outdoor air quality, there is a risk of bringing outdoor pollutants into the room. Natural ventilation is some...
