Air balancing is the process of optimizing an HVAC system to ensure that air conditioning outputs are consistent, and temperatures are comfortable in all rooms of the house or building.
Air Balancing HVAC Systems
In its simplest form, air balancing is the process of testing and adjusting your air conditioning system to deliver the right amount of air to each room in your home. Air balancing a distribution system is needed to properly direct the air flow in order to optimize the system’s design. Flow rates are tested, adjusted, and balanced as cubic feet per minute (CFM) or cubic meters per hour (m3/h).
Methods of Air Balancing
- Predictive Balancing
- Proportional Balancing
How to Balance a Residential HVAC System?
Find the tonnage or heating output to determine required system airflow. Divide the total system airflow so each room has its share. This can be done using Manual J or one of several estimating techniques, including calculating air changes.
Throughout the life of HVAC industry, air balancing remains the only way to assure your customers that you have delivered what you promised – comfort and efficiency. HVAC System performance measurement and energy analysis calculations have far eclipsed basic residential air balancing in recent years. To a basic air balance report now can be added equipment and system BTU measurement, static pressure and temperature profiles, live duct leakage, refrigerant and combustion adjustment and many other tests.
