Combined Space and Water CO2 Heat Pump System Performance Research for Efficiency and Demand Response

The Washington State University (WSU) Energy Program, in partnership with Cowlitz PUD, Energy Trust of Oregon (ETO), Idaho Power, Inland Power and Light, Northwest energy Efficiency Alliance (NEEA), Pacific Gas and Electric, Pacific Northwest National Laboratory (PNNL), Puget Sound Energy (PSE), Mitsubishi Electric and Sanden International proposes to conduct research on two types of combined space and water heat pumps in field and controlled experiments in existing homes of various efficiencies and climates. One technology uses carbon dioxide (CO2) refrigerant and will be tested for performance at six field sites and at the PNNL lab homes for efficiency and demand response capability. The second technology uses a conventional refrigerant and combines ductless heat pump space heating and cooling technology with water heating and will be field tested at five locations in the region's hottest and coldest climates as well as in the marine coastal zone. Costs of system installation, monitoring and retrofit will be collected and analyzed.
