Recovered water of the sprinkler environmental atmosphere by liquefying recovering moisture contained in the air blowing a cold environment surface, was obtained by collecting the wind blowing against the environmental, as sprinkling water recovered water thus recovered it is configured of a water-saving method of sprinkling water, which is characterized by to be used. In addition, a water recovery device for recovering the moisture in the watering environment atmosphere was evacuated then cooled in the cooling part of the heat exchanger and air is sucked watering environment atmosphere heat exchanger is provided, and recovered in the water recovery system was the structure of the water-saving-type sprinkler system that is characterized in that it consists of a reservoir tank for the recovered water, and a water spray nozzle for sprinkling water in the tank.環境面に風を吹きかけ、前記環境面に当たった風を回収して得た空気に含まれる水分を液化回収することで前記散水環境雰囲気中の水分の回収し、回収した回収水を散水用水として利用することを特徴とする散水用水の節水方法の構成とした。また、熱交換器が備えられ散水環境雰囲気中の空気を吸引し熱交換器の冷却部で冷却しその後排気して散水環境雰囲気中の水分を回収する水分回収装置と、水分回収装置で回収した回収水を貯溜するタンクと、タンクの水を散水する散水ノズルとからなることを特徴とする節水式散水装置の構成とした。
