ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) praised ASHRAE’s approval of Addendum d to ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality, which states that systems including chilled beams are not required to use a filter. The revision will be published in the 2016 edition of the standard, which is expected to be published this October.

“Members of AHRI’s Chilled Beams Product Section worked diligently to provide this proposal to the 62.1 Committee,” said Stephen Yurek, AHRI president and CEO. “I am pleased to see their hard work pay off, and for the committee to accept our members’ proposal.”

The addendum adds an exception to Section 5.8 of the standard, which currently requires particulate matter filters or air cleaners for all cooling coils or other devices with wetted surfaces. The AHRI Chilled Beams Product Section submitted a recommendation for this addendum because sensible-only chilled beams would not require filtration for wetted surfaces, as the coil surface would never be wet. ASHRAE agreed, and therefore the 2016 edition of Standard 62.1 will include the exception for cooling coils that are designed, controlled, and operated to provide sensible cooling only.
