PURPOSE: To reproduce a state similar to sweating of actual human body by controlling the quantity of supply area to a water phase part by a flow control valve to control the quantity of vapor generated in a saturation tank.
CONSTITUTION: A reduction valve 11 is provided on the downstream side from a tan no to reduce and govern the pressure of supply air, thus preventing the flow rate of air from being changed by the pressure variance. The lower end side of an air supply pipe 9 connected to a flow control valve 7 below the reduction valve 11 is immersed in hot water 2A1 in a saturation tank 6a. A gaseous phase part 2B1 of the saturation tank 6a and a hot water part 2A2 of a saturation tank 6b are connected by a means 9a, and air from the air supply tube 9 is blown into the hot water part 2A through a perforated tube 20 and reaches a gaseous phase part 2B and is blown into the hot water part 2A, and is supplied from the gaseous phase part 2B2 to a vapor supply tube 8. The temperature of hot water is kept constant by a temperature sensors in saturation tanks 6a and 6b. The gaseous phase part 2B2 of the saturation tank 6b and that of a box body 1 are connected to the vapor supply tube a, and air including saturated vapor is introduced into the box body 1 through the vapor supply tube 8 and is evaporated to the outside through an artificial sink 4.
