Hi, I've just started trying to use the converter program to generate .EPW files from source data which includes dry bulb and wet bulb temperatures - is it reasonable to expect the converter to calculate both dew point and relative humidity values? The documentation suggests so, but my results suggest otherwise.
The source data is comma separated and looks a little like this:
1,1,1,0,0,-3.5,-4,103720,250,3.6011108,0
The relevant part of the .def file looks like this:
DataElements=month,day,hour,glohorrad,difhorrad,drybulb,wetbulb,atmos_pressure,winddir,windspd,opaqskycvr
DataUnits=x,x,x,'Wh/m2','Wh/m2','C','C','Pa','deg','m/s','x'
DataConversionFactors=1,1,1,1,1,1,1,1,1,1,1
In this example I have -3.5 degC DB and -4 degC WB in the input, the resulting line in the output EPW file has -3.5 degC DB, -4.9 degC DP (which seems fine) and 138% RH (which is clearly wrong, and should be more like 89%).
Anyone have an idea what my obvious mistake might be?
Cheers,
Nick
