The following data relates to the office air conditioning plant having maximum seating capacity of 25 occupants. Outside design conditions: 34C DBT, 28C WBT Inside design conditions: 24C DBT, 50% WBT Solar heat gain: 9120 W Latent heat gain per occupant: 105W Sensible heat gain per occupant: 90W Lightening load: 2300W Sensible heat load from other sources: 11630W Infiltration load: 14m/min. Assuming 40% fresh air and 60% of recirculated air passing through the evaporator coil and by-pass factor of 0.15, find the dew point temperature of the coil and capacity of the plant. Note: Use psychrometric chart. [CLO3, PLO3 / 10 Marks]
