Method&Equations
Option 1
Outlet air temperature is given
Outlet air flow is calculated according to the relative humidity at the given temperature.
Outlet water temperature is given from the energy balance.
Options 2 and 3
Outlet water temperature is given or Approach temperature
is given
Energy balance gives the Air outlet temperature and moisture is calculated according to this temperature.
Warnings
Neither outlet air or water temp given. Assume air saturated at inlet air temp.
Variable inlet stream is zero!
Errors
Temperature calculation did not converge!
Cooling tower calculation did not converge!
