Question
Q1- The following data relates to the office air conditioning plant having maximum
seating capacity of 25 occupants:
Outside design conditions
Inside design conditions
Solar heat gain
Latent heat gain per occupant = 120 W
Sensible heat gain per occupant = 100 W
Lightening load
Sensible heat load from other sources = 11000 W
= 34°C DBT, 28°C WBT
= 24°C DBT, 50% RH
= 9120 W
= 2500 W
Infiltration load
= 16 m / mim
tas(ADP)
= 8 °C
Assuming 30% fresh air and 70% of recirculated air passing through the evaporator coil and
the by-pass factor of 0.15, find the dew point temperature of the coil, capacity of the plant,
Volume flow rate of supply air, Supply air temperature.
