We make two stage evaporative coolers and use water as cooling media. In the first stage we plan to use normal water for sensible cooling and in the second stage adiabatic cooling.
We need to know more about the following:
1) What is the average water temperature coming out of the ground in three seasons - summer, monsoon and winter?
2) What is the temperature of water if it is stored in overhead tank (concrete tanks)?
The data will help us design the cooling coil. It will save lots of energy in cooling water up to 7 degree Celsius.
Thank you
