Energy-saving method of water flowing and evaporative cooling of building

Abstract

The invention discloses an energy-saving method of water flowing and evaporative cooling of a building, belonging to the technical field of buildings, and in particular relates to a technology for utilizing water flowing and evaporative cooling modes on a building enclosure structure to lower the internal temperature and the external temperature of the building. In the method, a waveform surface (concave-convex) plate type material which is internally provided with rowed straight orifices is installed to be in a building enclosure structure, a water source is switched in, water is full of a pipy cavity made of the plate type material along with a passage and is heated with the conditions of sunlight and the like, a part of the heat is dissipated in a top evaporation mode, and the other part of the heat is consumed through water flowing, thereby lowering the temperature of the surface of a building enclosure, and further inhibiting rising of the internal temperature. While, in a rainy and freezing day in winter, a water source hole is closed to exhaust hydrops, and the enclosure structure can also fulfill the function of cold protection, therefore, the invention totally reaches the purposes of reducing the energy consumption of an air conditioner and realizing environmental protection and energy saving.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a technology for reducing the temperature inside and outside a building by utilizing water flow and evaporation on a building envelope. Background technique [0002] Currently known building envelope materials are usually laid with materials that block sunlight and have low thermal conductivity to achieve the purpose of building cooling. To cool down the building body by absorbing heat through the property of water, the existing Japanese institutions use photocatalyst coatings made of titanium oxide and other materials to paint on the outer walls and roofs of buildings, and then pour water on them. When the water evaporates, the heat will be taken away and reduced. building surface temperature. Domestic patent application number 200910135564.5, patent name: a building evaporative cooling energy-saving method, which refers to using cement and clay products as buildi...

AI Technical Summary

Problems solved by technology

None of the above methods can solve the destructive effect of winter rain and freezing weather on materials, and the timeliness is low

Especially in the domestic evaporative cooling method, the water storage on the surface of the product will turn into destructive power under severe conditions

However, in the application of water flow to reduce the temperature of buildings, there is still a blank in the existing construction field, and there is no research on the combination of two cooling methods, water flow and evaporation.
