District cooling systems are commonly used to serve applications like cities, educational campuses, major medical facilities, and other large building complexes. When properly planned and executed, these systems can offer many environmental, efficiency, and economic advantages over other means of supplying heating and cooling services, according to Gary Phetteplace, lead author of the guide, which was overseen by ASHRAE’s technical committee on district energy.
For district cooling systems to be successful, their components must be designed to function as a properly integrated system. In addition, owing to the large capital investments involved, such systems must have long lifetimes and they must be efficient and remain so over the long periods necessary to recover these substantial capital investments.
“To achieve efficient operation and long life, proper design is essential,” Phetteplace said. “This manual, along with a guide on district heating scheduled to be published in July 2013 will provide design guidance for all major aspects of district heating and cooling.”
In addition to design guidance, the book contains a chapter dedicated to planning, with additional information on system enhancements and the integration of thermal storage into a district cooling system. Guidance on operations and maintenance, including several case studies, is provided to help operators ensure that systems function as intended.
ASHRAE said the book is a resource for both the inexperienced designer as well as those immersed in the industry, such as consulting engineers with campus specialization, utility engineers, district cooling system operating engineers, central plant design engineers, and chilled-water system designers.
The cost of the District Cooling Guide is $119 ($99, ASHRAE members). To order, contact ASHRAE Customer Contact Center at 800-527-4723 (United States and Canada) or 404-636-8400 (worldwide), fax 678-539-2129, or visit www.ashrae.org/bookstore.
