Figure 12. Humidity stimulation based on the wet-bulb principle.

Effect of temperature on the parameters of the regression plane utilized to determine the response characteristic of the moist cell to oscillating changes in the wet-bulb temperature. a. yo intercept of the regression plane with the F axis reflecting the height of the regression plane plotted as function of the temperature level. b. Gain for the rate of change of the wet-bulb temperature plotted as function of temperature. c. Gain for the instantaneous wet-bulb temperature plotted as function of temperature. Relationships approximated by linear regressions [f = yo+aT]. R², coefficient of determination; the number of points per plot was 30.
