Designing Chilled Water Systems

Typically used for cooling and dehumidifying a building’s air, chilled water (CHW) systems circulate it throughout a building or campus complex. CHW systems also may be used for removing process or other heating loads.  Regardless of whether the design is for a new chilled water (CHW) system or a modification to an existing system, an early review of codes, standards, and regulations is necessary to allow for an expedient design and avoid conflicts that will cost time and money to resolve. Local, state, and federal codes and regulations will dictate permitting requirements that affect the location of buildings and equipment (central plants, cooling towers, buried piping systems), fuel handling and storage, environmental emissions and noise, water quality, and safety items.
