Importance of Neutral Indoor Air Pressure
Equalizing Indoor Air Pressure: A Crucial Balancing Act
It is important not to neglect the impact of an unbalanced ventilation system. If an air exchange unit does not expel and intake equal amounts of air, a negative or positive air pressure imbalance occurs. That being said may cause harm and energy loss to your home.
Positive air pressure
Positive air pressure pushes hot and/or humid air into walls and insulation; condensation can lead to mold, mildew and rot. Plus it causes heat loss.
Negative air pressure
Negative air pressure causes unconditioned air and risks of mold and higher energy costs. Plus a potential backdraft from combustion appliances.
Equal air pressure
Equal air pressure is the ideal state of ventilation. When supply airflow is equal (CFM) to stale air exhaust. Balancing is required on all units unless specified.
How to Determine Your Ventilation Needs
How much fresh air do I need?
Good air quality is based on the capacity of the home’s ventilation system.
Usually, the HRV’s or ERV’s capacity is measured in CFM (Cubic feet per minute) or L/s (Liters per second) of fresh air being distributed in the living space. To find out the CFM requirement you need to know the size of your home, plus the number of bathrooms and kitchen vents and gas appliances which have exhaust.
