In HVAC, “mechanical ventilation” describes your HVAC system’s air handler, ducts, and return vent’s capability to Handle indoor temperatures and equilibrium humidity amounts. Furthermore, it entails vents to exhaust destructive gases outside of the house designed in the heating procedure.
ODDB stands for Outside Dry Bulb. ODDB would be the dry bulb temperature from the outdoor air. It refers to the temperature that most thermometers and temperature sensors are effective at displaying.
In Particular occasions for instance a method change (eg: from regular method to fireplace manner), the valve or damper need to shut from an open placement.
