Problems solved by technology

This shows that the air conditioner is a vicious cycle heatstroke prevention and cooling technology device. The energy consumed by the air conditioner is finally converted into heat energy and heats the air in the surrounding environment, making the entire environment temperature higher and wasting a lot of energy.

Embodiment 1

[0022] Example 1: Heatstroke prevention and cooling in Changsha Railway Station

[0023] Changsha is hot in summer, known as the stove. The total area of ​​Changsha Railway Station is more than 77,000 square meters, including 19,000 square meters of houses, 37,000 square meters of squares in front of the station, and 21,000 square meters of railways between platforms. rice. The main station building of the railway station is 23 meters high, 151 meters wide, and the clock tower is 63 meters high.

[0024] On sunny days in summer, the waiting building of Changsha Railway Station uses air-conditioning to cool down, but the square in front of the station does not have any heatstroke prevention and cooling devices. Under direct sunlight, the heat wave on the ground of the square is very uncomfortable.

[0025] Reflective roller blinds 1 can be installed above the square of Changsha Railway Station. The reflective area of ​​a single roller blind is 50 square meters. A total of 750 ...

Embodiment 2

[0027] Example 2: Drought resistance and moisturizing of Dunhuang Crescent Spring

[0028] Crescent Moon Spring is located 5 kilometers southwest of Dunhuang City, Gansu Province. It is located at the foot of Mingsha Mountain. A lake is formed by the gushing of groundwater. Surrounded by sand dunes, it resembles a crescent moon, so it is named Crescent Moon Spring. In the 1950s, Crescent Lake was 218 meters long from east to west, 54 meters wide at the middle, with an average water depth of 5 meters and the deepest point was 7 meters. Due to the influence of human activities and climate change, the area of ​​the lake is shrinking day by day. At present, Crescent Spring is about 100 meters long from east to west, about 25 meters wide, with an average water depth of 3 meters and the deepest part of 5 meters.

[0029] In order to resist drought and keep moisture, reflective roller blinds 1 can be installed on the surface of Crescent Lake and the surrounding ground. The reflective...

Embodiment 3

[0031] Example 3: Drought resistance and moisture retention in Mu Us sandy land

[0032] The Mu Us Sandy Land is located in the transitional zone from the Ordos Plateau to the Northern Shaanxi Plateau. The sandy land covers an area of ​​about 40,000 square kilometers. In terms of administrative division, it includes 13 regions including the southern part of Ordos in the Inner Mongolia Autonomous Region, the northern part of Yulin in Shaanxi Province, and the northeastern part of Yanchi County in the Ningxia Hui Autonomous Region. County, city, banner. The Mu Us Sandy Land slopes from northwest to southeast, and the northwest includes some beam lands extending southeast from the central and western highlands of Ordos. The alluvial plains in the area are called beaches locally, which constitutes an alternate landform with "beams" and "beach" arranged in parallel. Its "Liang" land is mainly composed of Cretaceous purple-red and Jurassic gray-green sandstone layers. These sandsto...

Abstract

A cold island effect belongs to a phenomenon of climatic change. At present, the research of human beings on the cold island effect is only limited to the scientific filed, and is not related to the field of technical invention. By adopting the invention, the first application of a cold island effect principle in the technical field is realized for the first time. A cold island effect device disclosed by the invention comprises a plurality of reflecting devices, wherein the reflecting devices are arranged above the ground, water surfaces or buildings; the reflecting planes of the reflecting devices are parallel to or oblique to a horizontal plane, and most sunlight can be reflected back to the space, so that a relatively low-temperature cold island is formed in a surface region where the reflecting devices are positioned; and the cold island and surrounding atmospheric air form the cold island effect by interaction, so that the aims of heatstroke prevention cooling, resisting drought and preserving moisture are fulfilled. The cold island effect device can be widely applied to heatstroke prevention cooling of urban squares, residential areas and commercial areas as well as drought resistance and moisture preservation of dry lands, arid regions and deserts. Due to the adoption of the cold island effective device, combined application of ''cold island, photovoltaic effect and wind power'' can also be realized.

Description

1. Technical field [0001] The invention relates to a technical device which utilizes the principle of cold island effect to realize heatstroke prevention and cooling, drought resistance and moisturizing. 2. Background technology [0002] The cold island effect is a phenomenon of climate change. At present, human research on the cold island effect includes: the cold island effect of urban parks and the cold island effect of desert oases, and the research on the cold island effect is only limited to the field of science, and has not yet involved technology. field of invention. The present invention realizes the first application of the cold island effect principle in the technical field. [0003] The cold island effect of urban parks has a significant effect on urban summer heatstroke prevention and cooling, which has been proved in many scientific research documents, but cities are cities after all, and it is impossible to greatly increase the area of ​​parks in cities for s...
