The Commercial Refrigerator Manufacturers Section of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has approved for publication AHRI Standard 1250-2009, "Performance Rating of Walk-In Coolers and Freezers." The standard, which is available for free download at www.ahrinet.org, establishes definitions, test requirements, rating requirements, minimum data requirements for published ratings, operating requirements, marking and nameplate data, and conformance conditions for walk-in coolers and freezers.
The standard applies to mechanical refrigeration equipment consisting of an integrated single package refrigeration unit, or as separate unit cooler and condensing unit sections, where the condensing unit can be located either outdoors or indoors. Controls can be integral, or can be provided by a separate party as long as their performance is tested and certified with the listed mechanical equipment.
