Cooling Tower operation at a lower load?
Cooling Tower operation at a lower load?
(OP)
If I run a Natural Draft Cooling Tower at a heat load lower than its capability, keeping the hot water inlet temperature same for given ambient conditions, what will be the effect on the water outlet temperature?

Hope I am able to make the problem clear!

Try it or get a consultant to work out the numbers.

Anyway, I agree with Morten - in principle the cold water temperature will decrease when you lower the heat load and increase when you raise the heat load, but the magnitude of the changes will depend on the details. One of the critical factors is the "approach", i.e. how close is the cold water temperature to the wet bulb temperature. No matter how much you decrease the load, the cold water temperature will never go below the wet bulb temperature. But, as stanlsimon pointed out, in cold dry conditions the wet bulb temperature can go below freezing, and then your tower can freeze up.
