I have typical problem at hand. As a developer of a commercial building in Mumbai intend to maintain space humidity in range of 45+5% RH within the unoccupied floors. i.e No occupancy, equipment and lighting load. Floors are provided with AHU. Capacity are as per heat load calculation.
I attempted operating AHU throughout the day for 8 to 10 Hrs per day to dehumidify space. However achieved humidity is in the range of 65 to 73% RH only.
can any one suggest remedy to achieve 45+5% RH?
