The occupancy levels and activities of three zones A, B and C of an office building are given in Table P10.2.1. The design air flow rates required to meet the cooling loads of the zones are also tabulated. The summer outdoor conditions are 31°C and 70% relative humidity. The indoor relative humidity is 50%.

(i) Determine the indoor design temperatures for the three zones.

(ii) Determine the design ventilation air flow rates (Lsí1) for the zones.

(iii) Determine the total ventilation cooling load.
