energy savings from dual-source heat pump technology dual-source heat pump technology provides added degree of energy efficiency

 

the purpose of this technology installation review is to provide an overview of an assessment of an energy-efficient dual-source heat pump. the dual-source technology is a hybrid system that includes the use of both air and geothermal sources for the condensing process in the cooling mode and the evaporating process in the heating mode. the dual-source technology enjoys more favorable economics than a traditional ground-source heat pump, as the ground loop requirements are significantly smaller, reducing the initial cost of the system. included in this review is a discussion of the results of a field demonstration of a 3-ton system at fort stewart, georgia1, and a commercial retrofit demonstration for the u.s. post office in valrico, florida.
