An auditorium has to be air-conditioned (first by cooling and dehumidifying and then heating) for summer when the outdoor conditions arc: dbt 35 degree C, RH 70%; indoor conditions: dbt 20 degree C, RH60%, cooling coil dew point temperature 10 degree C. Amount of free air to be circulated 300 m3/min. Estimate (a) the capacity of the cooling coil and its bypass factor, (b) capacity of the heating coil and its surface to temperature when the bypass factor is 0.25 and (c) the mass of water vapour removed.
