PROBLEM TO BE SOLVED: To provide a sprinkling device free from the risk of being supplied water more than necessary and discharging the water.SOLUTION: In a sprinkling device, water is dripped to a mat 10 installed on the windward of a heat exchanger 31 of a refrigeration machine 1 via a water supply valve 58, vaporization heat is taken away from the air passing through the mat 10 according to the vaporization of water, and a condensation load is reduced. The sprinkling device includes: an outside temperature sensor 13 for measuring outside temperature; and an air temperature sensor 15 installed on the leeward of the heat exchanger 31, and for measuring the temperature of the air passing through the mat 10. It also includes a control unit 56 for opening/closing the water supply valve 58 based on a temperature difference between the temperature detected by the outside temperature sensor 13 and the temperature detected by the air temperature sensor 15. |
