Example 2. Winter Cycle
A room has a 18.0 kW sensible heat loss in winter and a 4.5 kW latent heat gain from the occupants.
Determine the supply air temperature and heater battery load using the following information.
DATA:
Indoor condition: 21oC dry-bulb temperature, 50% saturation.
Outdoor condition: -2oC d.b., 80% saturation.
The outdoor air and recirculated air ratio is 20%/80%.
No preheating or humidification takes place in this simplified example.
