Building evaporative cooling energy-saving method

Abstract

The invention discloses a building evaporative cooling energy-saving method, which comprises the following steps: (1) porous water storage material which is internally installed with a water chute and a connection water source port is manufactured and a through core pipe; (2) the porous water storage material is arranged outside a building space enclosing structure; (3) the through core pipe is switched into the connection water source port of the porous water storage material by a needling inserting mode so that the water chute of the porous water storage material can be communicated to be water guide passage; (4) from the top of the space enclosing structure, the water source is switched into the water chute of the porous water storage material so that the porous water storage material constantly keeps the wet state; natural phenomena such as sun energy, air convection and the like are utilized to cause the water building space enclosing structure to evaporate, thus reducing the temperature on the building space enclosing structure. The evaporative cooling energy-saving technique not only improves the thermal environment of architectural interior in hot summer and greatly saves the energy consumption used in air conditioner by human, but also plays a role in playing microclimate of a city and reducing the urban heat island of the city.

Description

technical field [0001] The invention belongs to the field of building technology, and in particular relates to a technology for realizing passive cooling and energy saving of building enclosure structures by using solar energy evaporation cooling, and meeting the needs of sustainable development of human settlements in a natural and harmonious manner. Background technique [0002] With modern air-conditioning equipment technology today, it is possible to change the indoor climate at will. But while it brings comfort to the non-poor, who make up 80 percent of the world's population, it comes at a heavy price, consuming far more energy than is used to light and heat buildings. In addition, my country has a population of 1.3 billion. If all air-conditioning equipment is used, the national energy reserves will not be able to meet its huge consumption. Therefore, the fundamental way to improve the indoor environment of buildings in hot summer lies in the building itself. It is t...

In addition, although the principle of water evaporation cooling is simple, this irreversible thermodynamic process is extremely complex. Only the heat transfer and moisture transfer in building materials and structures involves the integration of materials science and engineering, building thermal engineering, engi
