Solving for Wetbulb Temperature with Excel thread770-144858

[DesM1]

I am trying to write a programme in Excel to provide the performance of refrigeration evaporative condensers for each hour of the year. This is necessary to predict savings (due to lowering the condensing pressure) for different sizes (and capital costs) of condenser.
I came across thread 770-144858 of Jan06 but there was no reply/conclusion.
The problem is that climatic data (hourly) is available as dry bulb temp, humidity, dew point. To use the data provided by the condenser manufacturers I need dew point.
Has anyone worked out how to do it in Excel?

There is probably a mistake in your question:you wrote"...data (hourly) is available as dry bulb temp, humidity, dew point. To use the data provided by the condenser manufacturers I need dew point."
What is the correct question?

Sorry, I am looking for wet bulb temp using inputs of dry bulb and humidity.

Have a look at the following two threads - they discussed pretty much what you are after.
