PROBLEM TO BE SOLVED: To provide means for lowering temperature on a wide surface area in a short period of time, for example, for a pool side surface at a school during summer season where the temperature rises to as high as 60°C and water sprinkled thereon gets dry immediately, therefore possible burn on a sole of a foot or heat stroke is a concern, and such means is necessary for ensuring a smooth class lesson also.MEANS FOR SOLVING THE PROBLEM: A water spray hose perforated with a plurality of small holes is laid on a pool side and water is made to flow therethrough, enabling water to be sprayed over an entire surface to be cooled uniformly and continuously, lowering the surface temperature by 10°C or more in a short period of time, and lowering a sensory temperature also by vaporization heat when mist is sprayed on a human body. By using water spray hose for agriculture perforated with holes of a small diameter, inner pressure of the hose is maintained to enable uniform and continuous water spraying on a wide surface area.SELECTED DRAWING: Figure 1 |
