Construction of a climatometer, a type of “effective temperature” thermometer, and the experimental results with it are described. In order to improve the climatometer, resource with skin surface and body temperature variation in males by environmental heat condition cited from a paper, “Electrical Analog Simulation of Temperature Regulation in Man”, by R. J. Crosbie, J. D. Hardy and E. Fessenden is introduced.
The climatometer directly indicates in degrees cetigrade a measure derived from environmental temperature, namely, “equivalent temperature” felt by human body. The effective temperature is a function of air temperature, relative humidity, air velocity and heat radiation from distant heat sources. The climatometer comprises a new special sensitive element whose surface temperature is affected by any change of each factor described above, and a measuring part which indicates the temperature of the sensitive element.
In the paper described by R. J. Crosbie et al., skin and body temperature in man were analyzed by an analog computer applied to a one-dimensional physical model, namely, the slab model in place of human body. The slab model consisted of three layers and each was assumed to have a temperature which was constant throughout the thickness. For each layer, a separate one-dimensional heat flow equation was applied which contained_time as the sole independent variable. As the solution, graphical representation of skin and body temperatures versus ambient temperature was obtained. The data offer valuable_information in improving and developing a climatometer.
