Back Up Your Geoexchange System

摘要

If you're considering a geoexchange system but aren't sure if the performance will be reliable enough, consider hybridizing your system. You can pair your loop field with a backup system, such as a boiler, chiller, cooling tower, underfloor air distribution, or ice storage. "A lot of owners hybridize for peace of mind because it's not always preferable to put all of your eggs in one basket," says Rick Hermans, director of training and advanced applications for McQuay International, a manufacturer of HVAC equipment. "An added boiler or cooling tower gives an owner the assurance that the load will always be met." This strategy is ideal for existing buildings, properties constricted by available land, and facilities that anticipate expansion.
