Comfort Ranges Drawn up Based on the PMV Equation as a Tool for Evaluating Thermal Sensation

When dimensioning closed rooms according to the thermal sensation solving the relevantequations is necessary for a prediction of the PMV and for the determination of the surfacetemperature of clothing without using expensive simulation programmes in many cases, sincethey are not available for every designer.Thus we considered the drawing up of thermal comfort ranges as necessary plotting the PMVranges corresponding to the categories A, B and C of the general thermal comfort according tothe standard CR 1752.We have determined the terminating lines on both sides of the comfort range plotted for thispurpose by fixing the values PMV = 0.2, 0.5 and 0.7 using Fangers equation on the tlevtksplane. When drawing up comfort ranges for different applications we have considered thechanges in relative humidity and air velocity as well.
