Scope
Main technical content: This document specifies the terms and definitions, product classification and marking, basic requirements, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, and quality commitments for high-efficiency open cross-flow cooling towers used in computer rooms. This document applies to single-tower cooling water volumes of less than 1,000 m3/h, allowing fan speeds to vary within the range of 50% to 100% and circulating cooling water flow rates within the range of 40% to 110%, and is used for high-efficiency computer room cooling systems equipped with water spray fillers and mechanically ventilated open cross-flow cooling towers (hereinafter referred to as "cooling towers").
