An air conditioning system is to be designed for a restaurant with the following data: Outside design conditions = 40C db, 28C wb Inside design conditions = 25C db, 50% RH Solar heat gains through walls, roof and floor = 5.87 kW Solar heat gain through glass = 5.52 kW Occupants = 25 Sensible heat gain per person = 58 W Latent heat gain per person = 58 W Internal lighting load = 15 lamps of 100 W 10 fluorescent tubes of 80 W Sensible heat gain from other sources = 11.63 kW Infiltration air = 15 m3/min If 25% fresh air and 75% recirculated air is mixed and passed through the cooling coil, find: a- The amount of total air in m3/h. b- The dew point temperature of the coil. c- The condition of the supply air to the room. Assume the BPF = 0.2 Draw the schematic diagram of the system and show the system on psychometric chart.

Question
Q4/ An air conditioning system is to be designed for a restaurant with the following data: Outside design conditions = 40C db, 28C wb
Inside design conditions = 25C db, 50% RH
Solar heat gains through walls, roof and floor = 5.87 kW
Solar heat gain through glass = 5.52 kW Occupants = 25
Sensible heat gain per person = 58 W Latent heat gain per person = 58 W Internal lighting load = 15 lamps of 100 W
10 fluorescent tubes of 80 W Sensible heat gain from other sources = 11.63 kW
Infiltration air = 15 m3/min
If 25% fresh air and 75% recirculated air is mixed and passed through the cooling coil, find:
a- The amount of total air in m3/h.
b- The dew point temperature of the coil.
c- The condition of the supply air to the room.
Assume the BPF = 0.2
Draw the schematic diagram of the system and show the system on psychometric chart.
