A Mechanical Room of Its Own

Before the start-up of a 20,000-square-foot mechanical room, the Myriad Convention Center in Oklahoma City, Okla., received its heating and air-conditioning supply from an outside power-generation provider. Now, the 29-year-old convention center finally has a physical plant of its own. Not only can it generate its own heating and air conditioning, but it can also share these services with a sports arena across the street, home of the Central Hockey League's Oklahoma City Blazers.

For heat and hot water, the new mechanical room is equipped with four steel firetube hot-water boilers, each operating at a capacity of 16,730 MBtuh. Water circulation is handled within a closed-loop system by 12 large horizontal split-case pumps, four end-suction pumps, eight expansion tanks and various suction diffusers, air separators and multipurpose valves.

Four 1,350-ton-capacity centrifugal chillers and a 20-foot tall condensing water-storage tank provide air conditioning and ice making for the arena's ice rink. In addition, the system includes four 4,050-gpm cooling towers.

All of the new equipment is centrally controlled by an energy-management system that runs on Windows NT software and can be operated from a remote workstation PC or laptop computer. According to William Novak, chief engineer at the convention center, the system can page him to report the exact nature of equipment problems.
