ARLINGTON, VA — The Air-Conditioning and Refrigeration Institute’s (ARI’s) General Standards Committee recently approved the release of two updated ARI Guidelines. They are: Guideline G-2002, “Mechanical Balance of Fans and Blowers,” and Guideline T-2002, “Specifying the Thermal Performance of Cool Storage Equipment.” Both guidelines are currently available for free download

ARI Guideline G-2002 provides fundamental information and guides the industry on balance and vibration technology as applied to impellers used in air moving systems. It also includes terminology and methods of balancing practiced by the industry. ARI says the guideline is intended to apply specifically to system vibration and mechanical balancing as related to fans and blowers.

ARI Guideline T-2002 establishes the minimum information required for specifying cool storage equipment. It also applies to thermal storage equipment for use in cooling systems, which may be charged and discharged with a variety of heat transfer fluid, and is either fully factory assembled on site from factory supplied components or field erected in accordance with pre-established design criteria.
