Schools Fight COVID with Increased Ventilation and Airxchange® Interchangeable Segments

energy recovery ventilation protect IAQ from COVID

Schools Fight COVID

As schools and universities prepare to reopen, proper ventilation is of utmost concern.  To reduce airborne transmission of viruses, the ASHRAE Epidemic Task Force recommends educational facilities have air handling systems capable of achieving 150% of current minimum ventilation air flow standards.

Airxchange® Energy Recovery Wheels are built with interchangeable segments that allow schools to easily modify their ventilator systems and increase ventilation rates with PDX segments.  PDX segments reduce air resistance with a unique low air pressure drop design.

PDX segments can be installed in existing Airxchange® wheels with no unit modifications.  Simply replace the existing Airxchange® segments with PDX segments.  No other manufacturer offers this level of flexibility.

When used in conjunction with other system improvements, PDX segments can help achieve the 50% increase in ventilation recommended by ASHRAE.  To fully understand if there are other system impacts, consult a design professional.

Can Energy Recovery Systems Solve the Energy and Humidity Problems of Higher Outdoor Air Flow in Schools?

Energy recovery technologies reduce or eliminate the humidity control, energy cost and sizing problems associated with ASHRAE Standard 62-1999 in education buildings, auditoriums and other buildings with very high occupant density.

Available literature, studies and other modeling studies suggest that both latent and sensible energy recovery systems may significantly reduce or eliminate the associated problems of controlling thermal comfort, reducing energy costs and downsizing equipment needs while meeting the outdoor air requirements of ASHRAE Standard 62-1999 in high occupant density buildings. An energy recovery system is an effective, reliable option that provides affordable fresh air.

The School Advanced Ventilation Engineering Software (SAVES) package is a FREE tool to help school designers assess the potential financial payback and indoor humidity control benefits of Energy Recovery Ventilation (ERV) systems for school applications.
