Measured Space Conditioning and Water Heating Performance of a Ground-Source Integrated Heat Pump in a Residential Application

Abstract

In an effort to reduce residential building energy consumption, a ground-source integrated heat pump was developed to meet a home’s entire space conditioning and water heating needs, while providing 50% energy savings relative to a baseline suite of minimum efficiency equipment. A prototype 7.0 kW system was installed in a 344 m2 research house with simulated occupancy in Oak Ridge, TN. The equipment was monitored from June 2012 through January 2013.
