Things are a lot different now than they were 20 years ago; this may be doubly true when it comes to the industry perception of heat pumps. Now, the technology is more widely accepted. Contracting Business reports that ASHRAE now has a new book, titled “Geothermal Heating and Cooling: Design of Ground-Source Heat Pump Systems (GSHP).”
Steve Kavanaugh, professor emeritus at the University of Alabama, and Kevin Rafferty, a consulting engineer, Klamath Falls, Oregon, authored the book. Both have worked for 25 years with the technology.
“One of the realities of the GSHP industry is that, to some degree, it has been a victim of its own success,” Rafferty said. “Years ago the struggle was to simply get design teams to consider using the technology. Though this is still an issue in some areas, nationally it is far less of an issue than 20 years ago.
There is now fairly wide recognition of the benefits of GSHP systems, particularly on the part of building owners in the schools and office building sectors, where the technology has achieved its highest penetration rates. However, there also is a widely held view that anything bearing the name ‘geothermal,’ ‘ground source’ or ‘earth energy’ will produce the desired high efficiency/low operating cost. As a result, poorly designed systems are often installed and building owners expectations are unmet.”
