Clothing Wear and Tear of Heat Pump vs. Electric Clothes Dryers with Addendum
Heat pump clothes dryers are significantly more energy efficient than conventional (ENERGY STAR®) electric resistance clothes dryers. The goal of this project was to determine whether heat pump clothes dryers offer non-energy benefits—specifically, reduced clothing wear and tear—that could help consumer adoption. Multiple machine types ran over 100 dryer cycles, using loads specifically chosen to…

HPWH Lab Report_Sanden GAU_09.18.2013
Heat pump water heaters (HPWH) with an outdoor heat exchanger are a promising technology to more efficiently heat water. This project conducted lab tests of a variable-speed, CO2 refrigerant HPWH with the heat exchanger located in the outdoor unit. The testing plan included observing heat pump efficiency at a range of outdoor ambient temperatures from…

Revising the TV Energy Use Test Procedure: Incorporating HDR and other Needed Changes
The measurement method of television energy consumption has been largely consistent within the United States for the last decade. TVs have improved remarkably in energy efficiency during that time. It is important to understand how much of those apparent energy savings are the result of fundamental improvements to TV technology itself versus optimizing how TVs…
