Detailed HVAC

HVAC tab in model data - Detailed HVAC

When the Detailed HVAC model option is selected, the HVAC tab is used to define:

• Operation/setpoint schedules (under the Heating and Cooling headers),

Note: With Detailed HVAC simulations the Heating on and Cooling on settings have no effect on simulations, other than to show/hide the schedule data. They are always used in Heating and Cooling design calculations though.

• Outdoor air ventilation requirement (under the Mechanical Ventilation header)
• Environmental Impact Factors
• Natural ventilation and
• Air temperature distribution settings.

Note: For heating and cooling design calculations the humidity and temperature setpoints and ventilation requirement data comes from the Activity and HVAC tabs as described under the 1-Simple HVAC column in the table under Detailed HVAC Activity data, regardless of the Detailed HVAC Activity Data setting.

The main HVAC data is entered by clicking on the <HVAC System> navigator node.

Further details of Detailed HVAC are provided in a separate section.
