Re: [EnergyPlus_Support] calculating DryBulb Temp



Dear Haniyeh,
You only need Air Temperature (which is DRY BULB TEMPERATURE), Mean Relative Humidity % and a PSYCHROMETRIC CHART to find Wet Bulb Temperature. You can get the chart from internet. Find the D.B.T from the lowest horizontal line and the intersection of this value with the Relative Humidity curve. The sloping line passing from this intersection will give you WBT on the uppermost curve.

Thanks.
So, is there any possibility to calculate WetBulb Temperature from these data?
precip-htotal ( mm/hour)
temp-hmean  (degC)
vapourpressure-hmean  (hpa)
relhum-hmean  ( %)
sunshine-htotal (hours)
Thanks

The temp-hmean is most likely the hourly mean dry bulb temperature for the last hour...nothing else on the list will help you.
