Problems solved by technology

However, these measures are very limited in mitigating the "heat island effect", and these technologies and measures are for the control of air pollution, smog sources and individual parts of the "heat island effect", rather than overall and comprehensive control

Embodiment Construction

[0022] The height of the sun changes constantly from east to west in a day, from summer solstice to winter solstice, and then from winter solstice to summer solstice in a year, so the direction of the incident light and reflected light on the concave mirror changes every day and every year. In the change, if the plane mirror or the concave mirror is improperly placed, the reflected light will shine on the building, and the effect of complete reflection cannot be reached. The present invention will solve this technical problem exactly.

[0023] From 10 o'clock to 17 o'clock in a day is the time when the sun is high and the solar radiation is the strongest, and the present invention mainly reflects the sunlight of this period. According to national regulations, the ratio of building height to building spacing is 1:1.2, and according to the fact that most of the urban building heights are below 30 floors, combined with the law of light reflection and experimental results, it can b...

Abstract

An urban heat island effect relief mirror is composed of an insulation board 1 and concave mirror 2 which are integrated. A plurality of blocks of concave surfaces are formed on the insulation board in a pouring or vacuum aluminum plating method, and then a layer of reflective materials are coated on the concave surfaces to form the concave mirrors. The concave mirrors are fully distributed on the outer surface of the insulation board in a step mode. During use, the urban heat island effect relief mirror is attached to outer walls and roofs of buildings or the grounds, the insulation board is used for heat preservation, and the concave mirrors are used for reflecting sunshine. The concave mirrors have a sunshine converging effect and inwards refract the reflected light rays so that when sunshine illuminates to the concave mirrors on the buildings, the reflected light stays away from the buildings due to inward refraction and instead spreads to the space, radiation of urban sunshine is reduced, and accordingly the urban heat island effect is reduced. The urban heat island effect relief mirror improves the current hot situation of cities, balances the temperature differences between cities and suburbs, prevents suburban pollutants from entering cities, and accordingly relieves urban air pollution.

Description

technical field [0001] The urban heat island effect mitigating mirror belongs to the field of environmental protection, specifically a kind of urban heat island effect mitigating mirror. [0002] Background technique [0003] The situation of global air pollution and "heat island effect" is very serious. In terms of air pollution, it mainly presents the characteristics of soot-type pollution: the concentration of total suspended particulate matter in the urban air environment generally exceeds the standard; sulfur dioxide pollution remains at a relatively high level; The amount of nitrogen oxides has increased rapidly; nitrogen oxide pollution is showing an aggravating trend. In terms of "heat island effect", with the rapid expansion of city scale (population, area, building height and concentration) and the serious air pollution, the city's "heat island effect" is becoming more and more obvious. Under the action of the "heat island effect", the temperature in each place i...
