ASHRAE’s 2014 Annual Conference, which will be held June 28 to July 2 in Seattle, will feature a new track on ground-source heat pumps.
Organized by ASHRAE, the National Ground Water Association, the International Ground Source Heat Pump Association, and the Geothermal Exchange Organization, the track, “Ground Source Heat Pumps (GSHP) State of the Art: Design, Performance and Research,” will address all aspects of design leading to optimally performing systems, as well as avoidance of common pitfalls leading to poorly performing systems.
“There are a number of challenges that engineers face that are different from conventional HVAC systems, such as ground coupling, working with drillers, the importance of annual heating and cooling loads to ground-heat-exchanger design,” ASHRAE member Jeff Spitler, who helped create the track, said. “This track addresses the entire design and installation process from site evaluation to commissioning and system operation. In addition, GSHP systems are inherently energy-efficient, but poor choices in the design can compromise this inherent efficiency. ‘What not to do’ is also addressed in the track.”
Spitler said researchers from around the world will discuss new advances in the field, giving attendees the opportunity to hear about both the latest research and state-of-the-art design practice.
“We want to help practicing engineers understand where the industry began, where it stands currently, and where it is headed,” Lisa Meline, recent chair of ASHRAE Technical Committee 6.8, Geothermal Heat Pump and Energy Recovery Applications, said. “We also hope to impart guidance to the practicing engineers on the ground-heat-exchanger portion of a ground-source design. Many engineers shy away from this type of design because they don’t understand it. We want to change that and reinforce the need to provide single point of responsibility for all different types of HVAC-system designs, including this one.”
The technical program will begin June 29 with interactive programs and a networking coffee break. Sessions in the GSHP track will be:
