Mechanical Ventilation/Air distribution

HVAC tab in model data

Check the mechanical ventilation checkbox to indicate that outside air and/or recirculated air is delivered to the zone. You can use this setting to define mechanical ventilation and air delivered through centrally ducted air conditioning systems. Simple and Compact HVAC options share many of the same data fields. Data which applies only to Compact systems is indicated in the text below.

Note that Mechanical Ventilation data refers to the fan-powered air delivery through the main HVAC system and not a separate mechanical ventilation system.
