Example 1. Summer Cycle
A room is to be maintained at 22oC dry-bulb temperature, 50% saturation, when the sensible heat gain is 10.8 kW in summer.
The latent heat gain is 7.2 kW.
Determine the cooling coil and reheater outputs required by using a psychrometric chart if the plant schematic is as shown below.
DATA:
Outdoor condition is 28oC, 80% saturation.
The outdoor air and recirculated air ratio is 20%/80%.
The Apparatus Dew Point ADP is 8oC
Neglect the cooling coil contact factor.
