Question

An air conditioning system, shown schematically below, supplies air at the rate of 4 kg/s to a space maintained at a db-temperature of 27°C and relative humidity of 50%. The sensible and latent heat loads on the space are 46 kW and 20 kW respectively. Outdoor air at 35°C db-temperature and 24°C wb-temperature 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:

the supply air temperature in °C
the supply air relative humidity in %
the mass flow rate of the air that bypasses the cooling coil in kg/s
the refrigeration capacity of the cooling coil in kW
