PURPOSE:To obtain an air flow having a temperature lower than that in a room simply by a method wherein the air flow produced by a domestic use fan is cooled by the latent heat of evaporation of water. CONSTITUTION:When the fan 4 is operated, the air flow is collided against an evaporating unit 5 to evaporate the moisture and the air flow is cooled by the latent heat of the evaeporation. The lost moisture is supplimented to the evaporating unit 5 from a water reserving tank 3 through the water supplying ports 1 of a water supplying pipe 2. According to this method, the air flow having the temperature lower than the same in the room by 3-5 deg.C can be obtained by the domestic use fan. |
