In a winter heating air conditioning system 1 kg/s of ambient air at 70C DBT, 80% RH is sensibly heated, then adiabatically saturated to a high humidity of RH – 90%, and then further sensibly heated to the desired outlet state of 250C DBT and 50% RH.
Determine the temperature of air at various state points and show all the processes on a psychrometric chart. Also determine the amount of moisture added per hour in the adiabatic saturator.
