A: An air conditioning system, shown schematically in Fig. (1), supplies air at the rate of 4 kg/s to a space maintained at a DBT of 27C and relative humidity of 50%. The sensible and latent heat loads on the space are 46 kW and 20 kW respectively. Outdoor air at 35C DBT and 24C WBT is introduced at the rate of 1.1 kg/s. The relative humidity of the air leaving the cooling coil is 90%. The pressure is constant at 101.3 kPa. Determine (i) the supply air temperature and relative humidity, (ii) the mass flow rate of the air that bypasses the cooling coil, and (iii) the refrigeration capacity of the cooling coil. 3 6 C C 3 2b 2a space A: An air conditioning system, shown schematically in Fig. (1), supplies air at the rate of 4 kg/s to a space maintained at a DBT of 27C and relative humidity of 50%.
