The 20,500 sq. ft. build-out created two areas, the Broadcast Operations Center (BOC) and the surrounding office space. The BOC area, built on a 24"" raised floor, contains all the server racks and user consoles.
Project Overview
- Substantial cooling required for the BOC necessitated a condenser water system, which utilized eight Liebert water-cooled computer room AC units (200 tons total) and two open cooling towers (580 GPM each).
- The open/closed condenser water loops use 580 GPM centrifugal pumps and a pair of plate and frame heat exchangers.
- The surrounding office space is cooled by a 30-ton water-cooled Mammoth AC unit, which pumps 11,000 CFM of air through exposed ductwork.
- Each zone has eleven VAV boxes and two cooling-only water source heat pumps that supplement the cooling for the heat generating UPS and LAN/TELCO rooms.
