Effect of saturation efficiency of direct evaporative cooler on indoor conditions and thermal comfort in a small office room of a building

Through a simulation study, thermal comfort of occupants and indoor air relative humidity in an office have been assessed. The authors observed that it is not always desirable to have cooler with higher saturation efficiency for applications where low indoor air relative humidity is of primary concern, in that case an ordinary evaporative cooler can be used that allows slightly higher air change rate within the occupied space.
