Study of Heat Pump Performance in U.S. Cities
N/A
Paper prepared for a September 2013 conference.
For the 7th International Conference on Energy Efficiency in Domestic Appliances and Lighting (EEDAL ’13), Kenji Takahashi and colleagues prepared a paper discussing the methodologies and results of a Synapse study on heat pump performance. The study examined the hypothetical operation of two “efficient” HVAC technology options—a two-stage heat pump and an inverter pump—for single family homes that were built around 1990 and that require replacement of a ducted HVAC system. Synapse then compared those options to a reference-case option—consisting of an efficient natural gas furnace and a central air conditioning system—on the basis of energy, environmental, and economic impacts for 11 U.S. cities with varied climates.
