Extracted text: Q.1 An air conditioning system supplying air to a space with a sensible heat load of 14 kW and a latent heat load of 9 kW has a cooling coil and a bypass path as shown schematically in Fig. The db- temperature of the space is maintained at 26°C. The dry air mass flow rate of supply air is 1.2kg/s. Outdoor ventilation air at 34°C db-temperature and 50% relative humidity is introduced into the system with a dry air mass flow rate of 0.26 kg/s. The air leaving the cooling coil is fully saturated at a db-temperature of 6°C. The pressure is constant at 101.3 kPa. Determine db-temperature and relative humidity of the supply air to the space, (ii) (i) (ii) (iv) wb-temperature of the space, temperature of the air entering the cooling coil, and refrigeration capacity of the cooling coil.
