Wall body evaporation and temperature reduction device utilizing solar energy and nontraditional water sources

Abstract

The invention discloses a wall body evaporation and temperature reduction device utilizing solar energy and nontraditional water sources. A solar cell panel of the wall body evaporation and temperature reduction device is placed on a building roof and is connected with a controller through a conducing wire, the controller is connected with a storage battery, the storage battery is electrically connected with a water pump, the water pump is respectively connected with a water supply pipe and a water spraying pipe, the water supply pipe is connected with a water storage tank, the water pump is also connected with a calculator through signals, the water spraying pipe is arranged at the upper part of the outer side of the wall surface, an air temperature probe, an air humidity probe and a wall surface moisture content probe are respectively connected with the calculator, the air temperature probe and the air humidity probe are placed on the roof, and the wall surface moisture content probe is placed at the bottom of the wall body. The wall body evaporation and temperature reduction device has the advantages that the matching relationship among the solar energy, the ambient temperature and humidity of the wall body and the wall surface moisture content is skillfully utilized, through the intelligent control of the calculator, the effect that the water spraying and temperature reduction of the wall body is only carried out under the conditions of outdoor high temperature and high solar radiation is realized, and the building energy saving and water saving effects are obvious.
