Wet bulb Temperature Calculation

The module calculates the wet bulb temperature based on the dry bulb temperature and relative humidity using an approximation formula:

WetBulbTemp = 0,005 * Temp* RelHum + 0,55 * Temp+ 0,042611 * RelHum-4,57444

The absolute error in the wet bulb temperature calculation is less than 1 K if Temp = [0...40°C], RelHum = [15...80%], air pressure of locations up to 2000 msl (meter above sea level).
