The center's latest research has involved dealing with minimum air conditioner and heat pump efficiencies - specifically finding ways to increase efficiency without increasing size too much, and without using R-22.
Most changes involve component innovations. He described some of the center's findings at the International Energy Agency (IEA) Heat Pump Conference in Las Vegas. The session was co-chaired by professor Thomas Kopp, an energy engineer from Switzerland, and Glenn Hourahan, P.E., of the Air Conditioning Contractors of America (ACCA).
