The following data relates to the office air conditioning plant having maximum

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]
