摘要

Larger buildings, process facilities, and other appli cations use chilled water cooling systems for its many advantages, including refriger ant and maintenance containment, energy efficiency, and lower first cost. While the chiller is typically the most expensive, most energy consuming, and most visible part of the system, other key compo nents include chilled and condenser water pumps, cooling towers, heat exchangers, and hydronic special ties such as water pressure regula tors, air separators, and chemical feed pots. Controls are also critical to the system because they oper ate water valves, control setpoints, and schedule equipment. All these components and capabilities sup port the delivery of cooling water to the airside or process loads and carry unwanted heat to sources of heat rejection. This article will focus on maintaining these components "beyond the flange," which are found in most typical building comfort cooling applications.
