ASSESSMENT, CLEANING RESTORATION OF HVAC SYSTEMS (ACR-2002)

摘要

In the fall of 2001 NADCA released ACR 2002, which supercedes 92-01. This new standard holds to the same clearance criteria for post cleaning requirements but goes much farther in addressing pre-cleaning assessments, control and containment during the cleaning process as well as a host of other variables that can impact the indoor environment. This paper takes a look at the new standard and how it addresses the many variables that influence duct cleaning and IAQ and how the document deals with the many different building populations.
