SPRINKLER SYSTEM

PROBLEM TO BE SOLVED: To provide an all-season type sprinkler system which can sprinkle water on a roof of a house or a photovoltaic power generation panel device installed on a roof through all seasons so as to have a cooling effect, cleanse and melt snow.SOLUTION: In a sprinkler system which sprinkles water on a roof 1 of a house from sprinkling means 19 by operating a lift pump, cooling water and hot water heated by a water heater 9 can be supplied from the water supply side of the lift pump, and a solenoid valve for water heater of which a flow channel can be freely opened and closed is installed in a connection pipeline between the water heater 9 and the lift pump. In the summer season, by closing the solenoid valve only cooling water is supplied to the lift pump and is sprinkled on the roof 1 so as to cool the roof 1 or a photovoltaic power generation panel device 21 installed on the roof 1, while in the winter season, by opening the solenoid valve for water heater hot water from the water heater 9 is sprinkled on the roof 1 of a house from the sprinkling means 19.SELECTED DRAWING: Figure 1 【課題】家屋の屋根や屋根に設置した太陽光発電パネル装置に四季を通して散水できるように構成し、冷却効果と洗浄及び消雪ができるオールシーズン型の散水装置を提供する。【解決手段】揚水ポンプを作動させて散水手段１９から家屋の屋根１上に散水する散水装置であって、揚水ポンプの給水側に冷却用の水と温水器９により加温された温水を供給可能に構成し、温水器９と揚水ポンプとの接続配管路に流路を開閉自在な温水器用電磁バルブを設け、夏季には電磁バルブを閉操作することにより、冷水用の水のみを揚水ポンプに供給し、屋根１上に散水して、屋根１若しくは屋根１上に設置した太陽光発電パネル装置２１を冷却するようになし、冬季には温水器用電磁バルブを開操作して温水器９からの温水を散水手段１９から家屋の屋根１上に散水する。【選択図】図１
