An air conditioning system is designed under the following conditions:
Outdoor conditions– 30°C DBT, 75% R.H.
Required indoor conditions – 22°C DBT, 70% R.H.
Amount of free air circulated – 3.33 m3/s
Coil dew point temperature – 14° C
The required condition is achieved first by cooling and dehumidification, and then by heating. Estimate (i) the capacity of the cooling coil in tons, (ii) the capacity of the heating coil in kW, and (iii) the amount of water vapour removed in kg/s.
