I am modelling cooling energy demand for Delhi India, under climate change temperature projections for a climate change mitigation and adaptation plan.
However, as said, CDD are normally measured using dry bulb temps but this hugely underestimates cooling demand during the monsoon season as...
How exactly do you want an example, its simply the DI value calculated from the wb and db input into the CCD formula, a base temperature of 22 degrees C is used. These hourly CDD are then summed then divided by 24 to give daily CDD then summed over a year of month to give those CCD values...
I simply used the DI in the normal CDD equation,
so hourly CDD = (DI - base temperature)/24
I know this is not an established method, but doing just wet bulb temps underestimates the effect of peak summer temperatures.
I have not been able to find any literature, but does anybody know if it is possible to calculate CDD using a combination of wet and dry bulb temperatures.
I ask this because I have projecting cooling demand for Delhi India, and comparing current cooling degree days when just dry bulb temps...
I have Dry Bulb temps, relative humidity, dew point temperature, altitude, and pressure.
Cannot use a psychrometric chart as I have hourly values for the whole year which I need to convert, which I am then using to calculate Wet Bulb Cooling Degree Days.
I have used an excel add in already but...
Hi there,
I am in desperate need of Wet Bulb temperatures for Delhi however, there are no records that I know of available. I came across this thread thread403-273503, which outlined an excel function to calcualte the wet bulb from dry bulb, dew point, etc. However, I have no idea how...
