Instead of humidifying and humidifier they will be dehumidifying and dehumidifier as follows (3rd line from the bottom and last line)-
3. The following data refer to air conditioning of a public hall:
Outdoor conditions = 40ºC DBT, 25ºC WBT
Required comfort conditions = 24ºC DBT, 50% RH
Seating capacity of hall = 500
Amount of outdoor air supplied = 0.3 m3/min/person
If the required condition is achieved first by adiabatic dehumidifying and then cooling, find:
a) The capacity of the cooling coil and surface temperature of the coil if the by-pass factor is 0.4; and
b) The capacity of the dehumidifier and its efficiency.
