Example 3. Summer Cycle (Cooling Coil contact factor)
An office is to be maintained at 22oC dry-bulb temperature, 50% saturation in summer.
The sensible heat gain is 8.0 kW.
The latent heat gain is 2.0 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
The cooling coil contact factor is 0.8. (See explanation of contact factor in page 9)
