摘要

The impact on space conditioning energy use due to operating a heat pump water heater (HPWH) inside the conditioned space is analysed based on 2010-2011 data from a research house with simulated occupancy and hot water use controls. The 2700 ft~2 (251 m~2) house is located in Oak Ridge, TN (mixed-humid climate) and is equipped with a 50 gallon (189 L) HPWH that provided approximately 55 gallons/d (208 L/d) of hot water at 120°F (48.9℃) to the house during the test period. The HPWH has been operated every other week from December 2010 through November 2011 in two modes; a heat pump only mode, and a standard mode that utilizes 15355 Btu/ h (4500 W) resistance heating elements. The energy consumption of the air-source heat pump (ASHP) that provides space conditioning for the house is compared for the two HPWH operating modes with weather effects taken into account. Impacts during the heating and cooling seasons are compared.
