Auteurs : ARI

Type de monographie : Norme/Recommandation

Résumé

This standard establishes a single set of requirements for the testing and rating of capacity of thermostatic expansion valves, recommended standard maximum operating pressures for pressure-limiting type valves, recommended refrigerant designation and colour coding, and recommended standard connection sizes. Covered are thermostatic expansion valves for refrigerants R-12, R-22, R-502, and R-134a for use at evaporator temperatures between 50 and -40°F. This standard supersedes ARI Standard 750-2001 and can be downloaded from the ARI Web site: www.ari.org/MemberPortal/standardscert/standards/default.htm.
