されている。[Operation] FIG. 1 is a schematic explanatory diagram showing the main parts of the apparatus of the present invention. The box 1 provided with the simulated skin 4 is communicated with the gas phase part 2B of the saturation tank 6 via the steam supply pipe 8, and the saturation tank 6 contains hot water 2 having the same temperature as the human body.
A is accommodated. An air supply pipe 9 whose tip opening is immersed is disposed in the hot water 2A, and a flow meter 13, a flow rate control valve 7, and a blower 10 are provided on the upstream side of the air supply pipe 9. is connected to.

る。 After the air supplied from the blower 10 is adjusted to an appropriate flow rate by the flow rate control valve 7, it is supplied with hot water 2.
It is blown into A. Then, water vapor is taken into the bubbles that have come into contact with the hot water 2A, is diffused from the surface of the hot water 2A to the gas phase portion 2B, and is then temporarily retained in the gas phase portion 2B. Thereafter, the saturated water vapor is introduced into the box 1 through the steam supply pipe 8, and further diffused to the outside through the simulated skin 4.

で示される。 At this time, if the temperature of the hot water 2A is t°C and the flow rate of air blown into the hot water 2A is Qm 3 /h (t°C, flow rate under 1 atmosphere), the steam supply pipe 8 from the saturation tank 6
The absolute humidity D (gr/m 3 ) of the air sent to the side is expressed by the following equation.
Ｄ＝1.058・ls／１＋0.00366・ｔ （gr／m3）
［ただし、lsはｔ℃における飽和水蒸気圧（mm

流量調節弁７で調節しながら高精度な発汗状態を
人工的に再現することが可能となつたのである。 D=1.058・ls/1+0.00366・t (gr/m 3 ) [However, ls is the saturated water vapor pressure at t°C (mm
Hg)] Therefore, the amount of water (perspiration amount) A (gr/h) released from the simulated skin 4 is expressed as A=Q・D=1.058ls/1+0.00366t・Q, and the amount of perspiration A It can be seen that can be changed by increasing or decreasing the air flow rate Q. At this time, since the hot water temperature t can be arbitrarily controlled independently of the steam air amount Q, it is possible to simulate the hot water temperature t so that it always approximates the human body temperature regardless of the water vapor amount. . Therefore, it has become possible to artificially reproduce the state of sweating with high precision while adjusting the amount of sweating with the flow control valve 7.

Then, based on the pressure difference, it is blown into the hot water 2A 2 via the connecting pipe 9a and the porous pipe 20, and is fed from the gas phase part 2B 2 to the steam supply pipe 8 side. In addition, temperature sensors 14, 14 are arranged in each saturation tank 6a, 6b, and hot water 2A 1 , 2A 2 is heated based on the measured value of each temperature sensor 14, 14.
