Heating, Ventilation, and Air Conditioning (HVAC) systems are critical components of any building’s infrastructure. They control the temperature, remove impurities from the air, and regulate humidity levels. In recent years, the role of HVAC systems in controlling airborne diseases has come into sharp focus.
Airborne diseases can easily spread in enclosed spaces with poor ventilation. Many pathogens, including viruses and bacteria, can remain suspended in the air for hours. An HVAC system can limit the spread of these pathogens by regulating air circulation and quality.
- Improved Indoor Air Quality: A well-maintained HVAC system continuously filters out harmful particles from indoor air. This includes dust, allergens, molds and potential pathogens. By ensuring that fresh, clean air is always circulating indoors, HVAC systems minimise the chances of airborne disease transmission.
- Humidity Control: Humidity levels have a significant impact on pathogen survival and transmission rates. High humidity creates favorable conditions for mold growth while low humidity increases static electricity which may carry viral particles further. An efficient HVAC system maintains optimal indoor humidity levels (40-60%), thereby reducing opportunities for pathogen survival.
- Ventilation: Proper ventilation is crucial to diluting indoor airborne contaminants. Without it, pollutants will build up over time leading to unhealthy indoor air quality. An effective HVAC system ensures a steady circulation of outdoor air indoors to mitigate this issue.
- Air Filtration: High-efficiency particulate air (HEPA) filters are often used in HVAC systems to trap harmful contaminants such as bacteria and viruses. HEPA filters have a very high efficiency rate – they can capture 99.97% of particles that are 0.3 microns or larger in diameter.
To maximize their role in disease control, it is important to maintain and regularly service HVAC systems. This can include filter changes, duct cleaning, and system inspections to ensure they are operating at their optimal capacity.
In addition to standard HVAC systems, there are also specialized technologies that further support disease control efforts. These include ultraviolet germicidal irradiation (UVGI) systems and photocatalytic oxidation (PCO) devices which neutralize airborne pathogens.
However, while HVAC systems play a key role in disease control, they cannot replace other important measures like personal hygiene and vaccination. Thoughtful integration of HVAC technologies with public health strategies is crucial for comprehensive airborne disease control.
The COVID-19 pandemic has underscored the importance of indoor air quality. As we navigate this new reality, the role of HVAC systems in controlling airborne diseases will continue to evolve and become an even more critical component of public health infrastructure.

Demand-controlled kitchen ventilation (DCKV) is one of the advanced techniques used in HVAC systems, specifically designed for commercial kitchens. This technology reduces the energy consumption of a kitchen by dynamically adjusting the exhaust and make-up air flow rates in response to cooking activity.
The goal of DCKV is to provide enough ventilation to maintain indoor air quality and remove excess heat generated by cooking appliances, while minimizing energy costs. This system operates based on real-time demand, which means it ramps up during high-use periods and slows down during low-use periods.
How Does DCKV Work?
DCKV systems use sensors to monitor thermal loads produced by cooking appliances.
- Temperature Sensors: These sensors are installed at the hood level to detect changes in temperature caused by cooking activity. When the temperature rises, indicating increased cooking activity, these sensors send a signal to increase the speed of exhaust fans.
- Optical Sensors: These sensors detect smoke and grease particles that can build up over time in commercial kitchens. As such particles increase, these sensors signal an increase in exhaust fan speed.
Once signals are received from these sensors, the DCKV system increases or decreases ventilation accordingly.
Benefits of DCKV
- Energy Efficiency: By operating based on demand, DCKV can significantly reduce energy consumption compared to traditional constant-speed vent hoods.
- Cost Savings: Reduced energy usage translates into significant cost savings over time.
- Improved Air Quality: By effectively managing ventilation according to cooking load, DCKV improves indoor air quality.
- Noise Reduction: Variable speed fans are typically quieter than their constant-speed counterparts – making for a more comfortable working environment.
- Extended Equipment Lifespan: By operating at lower speeds when demand is low, the lifespan of ventilation equipment is often extended.
