An air handling unit consisting of an air mixer, a cooling coil, a heater, and a fan is used to supply conditioned air (Cp = 1 kJ/kg-K) to the room of 800 m³ internal volume. (a) With aid of the following table and equations, determine: Mass flow rates of the outdoor air intake and the recirculating air, (ii) Specific enthalpy, relative humidity, and moisture content of the air at the air mixer exit. Outdoor Air Intake Condition Interchange per Hour 3 30°C DB 80% RH QSL = m Cp At and ma = Design Condition Sensible of Room Load of Room 24°C DB 50% RH 16 kW Temperature Increased by Room Air 8°C DB NV 3600 (vo) (b) If 1 kg/s of air at 27°C DB and 65% RH is cooled and dehumidified to 20°C DB and 60% RH, determine the heat rejection at the cooling coil.
