Laboratory Equipment Cooling: Process Cooling Water System Design Strategies
Terry Brown, Research Facilities Design
Paul Lemestre, Research Facilities Design
Savings in initial capital costs and operational energy costs for laboratory HVAC systems can be realized by efficiently extracting heat loads from laboratory equipment through a process cooling water system. HVAC system operation often represents the highest operational cost for a laboratory building. With increasing equipment densities and heat source concentrations, laboratory ventilation rates often can be driven by cooling load demand requiring significant increase of air change rates above the minimum safety design levels. The use of a process cooling water system for rejecting heat from laboratory equipment can significantly reduce space cooling loads and corresponding air change rates. This presentation will discuss design strategies and solutions for process cooling water systems, examples of water-cooled equipment and instruments used in laboratory operations, and types of laboratory science buildings that might benefit from a process cooling water system.
