The Consortium for Energy Efficiency and Heat Pumps (EEHP)— formerly 'Alternative Cooling Technologies and Applications (ACTA)' — focuses on developing comprehensive information for the detailed physics of transport processes, innovative energy conversion components and systems, and new cost-effective test methods. Our faculty and students built the first CO2 hot water heat pump in the USA. No suitable compressors were available so we developed our own, establishing CEEE early on as the leader in carbon dioxide refrigerant technology. We also developed expanders and a thermoelectric sub-cooler, and explored all possible two-stage cycle options in order to recover irreversible changes associated with expansion process.
