HVAC Strategies to Control Transmission

According to ASHRAE, “Infectious aerosols can be disseminated through buildings by pathways that include air distribution systems and interzone airflows.” While there is no magic solution to eliminate the issues presented by SARS-CoV-2 or other airborne pathogens and viruses, ASHRAE experts agree there are several things that can be done to clean the air and decrease potential risk. ASHRAE has identified many strategies to help provide superior quality indoor air, including filtration, ventilation, relative humidity, and UV lights. Adhering to ASHRAE-approved guidelines and air cleaning devices, Daikin Applied and AAF are teaming up with design engineers, service contractors, and facility managers to make an important contribution in promoting better indoor air quality.

According to ASHRAE, the risk of airborne infections particles in filtration systems may be reduced by upgrading filtration systems to a minimum MERV-13, or the highest level achievable. In collaboration with AAF Flanders, Daikin Applied has developed specific guidelines to help identify some of the ancillary system effects that can occur when upgrading HVAC filtration.



According to ASHRAE, higher ventilation rates may reduce the risks associated with HVAC systems’ impact on the distribution and bio-burden of infectious aerosols within a building. A well-engineered and executed ventilation strategy will help provide more fresh air, while minimizing operation cost. Every application is unique due to the differences in buildings themselves and varying climate measures including humidity levels and temperature. Daikin can help develop a cohesive strategy to support your ventilation needs, helping you to navigate decisions involving retrofits, recommissioning, or potential new equipment solutions when applicable. Let our service professionals assist you to find the right solutions to minimize the possible increased energy usage.

Humidity Control

ASHRAE recommends keeping the relative humidity levels in your building between 40-60% and explains that if relative humidity is too low, dry airborne pathogens can exist longer and travel further. ASHRAE farther explains that if relative humidity is too high, moisture and mold can build up. Daikin Applied can help you develop a strategy to monitor and maintain your climate controls in accordance with ASHRAE recommendations.Contact Daikin Applied today to learn more about potential improvements to your building’s climate control.



UV Lights

Different UV light systems result in different indoor air quality effects. According to ASHRAE, while UVGI is well researched and validated, many new technologies are not proven. Find your local service provider to determine if retrofitting your system with UV lights is a possibility and how to maximize their effects on indoor air quality.

Remote Monitoring

Remote Monitoring

Many things have changed with recent shelter-in-place restrictions and a desire to limit visitors. Equipment and systems that make remote service and maintenance easier are a welcome option. These types of systems have been expensive in the past, but they are now available for a low cost from Daikin Applied with SiteLine™ Building Controls.

Important IAQ items such as economizer operation, fresh air ventilation, and proper operating temperatures and pressures can be remotely monitored. In the event service is needed, technicians can remotely view fault details and possibly reset the system. If a site visit is required, technicians can arrive more informed of the issue and with the necessary parts.
