HVAC Engineering: Understanding Air Balancing in Ventilation Systems

Fire Protection Engineering Magazine

Air balancing is a fundamental design skill in HVAC engineering. Depending on the intended purpose of each building area, it may require negative, positive or neutral pressurization. This is accomplished by adjusting supply and exhaust airflows: a higher air supply causes positive pressure, while a higher air exhaust causes negative pressure.

Although the ideal scenario would be to ventilate all building areas naturally, this is not possible in practice. For example, there is no way to use natural ventilation in areas that are completely surrounded by other rooms, as well as in underground levels. The purpose of ventilation can range from human comfort to facility safety: ventilation in residential and commercial settings is focused on delivering air of breathable quality, while industrial ventilation is often deployed to keep dangerous gases away from certain areas or below a certain concentration.

Indoor spaces are subject to many airflows, and they are normally measured in cubic feet per minute (CFM). We tend to think only about the outdoor air supply and the exhaust air, but consider there is also unwanted air escape (exfiltration) and air gain (infiltration). Unwanted air flows typically occur around the edges of windows or doors.

Poorly balanced ventilation systems often lead to air quality issues, according to HVAC engineering professionals. For example, negative pressurization may draw in pollutants from above the ceiling or from outdoors, and air may rush in suddenly when a window or door is opened. 

Intake and Exhaust Air Calculation

Before air balancing calculations, it is important to know the required air supply and air exhaust. There are many valid procedures, as indicated by the following codes:

  • ASHRAE 62.1 – Ventilation for Acceptable Indoor Air Quality
  • In the case of hospitals, ASHRAE 170 – Ventilation of Health Care Facilities

The total air supply is 60 cfm, while air exhaust is 150 cfm. Since exhaust is higher by 90 cfm, the result is negative pressurization. Increasing supply to balance airflow is acceptable, since the values provided in the code are only minimum values.

Assume all intake airflows are increased to the following values, in order to prevent negative pressurization:

  • Electrical room: 25 cfm
  • Corridor: 125 cfm
  • Storage: 25 cfm

This results in a total air intake of 175 cfm, which is higher than the 150 cfm of exhaust air. This causes cellar areas to be pressurized with respect to the trash room, preventing the spread of unpleasant odours. Since the airflow must be balanced at the end, the extra 25 cfm are released by exfiltration, but trash odour is confined to its intended location.

Troubleshooting Air Balancing Issues in HVAC Engineering

If a ventilation system suffers from air balance issues, do not immediately assume the cause lies in the fans themselves. Consider that system components such as dampers can be damaged, and also that air ducts can get disconnected. When in doubt, the best recommendation is getting a professional opinion from an HVAC design engineer.

When ventilation systems are equipped with variable frequency drives for fan speed control, air balancing is simplified. VFDs can adjust the rpm of both supply and exhaust fans, to match the ventilation load while keeping airflows balanced.

HVAC engineering is a complicated matter that is best approached by engineers that have specialized in this area of expertise.
