Reliability Development and Field Demonstration of CO2 Heat Pump Water Heaters
It is the objective of the proposed effort to improve and verify the reliability of compressors for CO2 heat pump hot water haters based on results from field trials in commercial applications. A key feature of this work is that carbon dioxide is used as refrigerant, which has been shown to lead to very compact and highly efficiency hot water heat pump systems. This effort focuses on low-cost, highly compact systems for commercial applications where long operating hours lead to very favorable payback periods in the range of one to five years depending on utility rates. The results of this effort will position CO2 heat pump water heater technology to change the state of the art in the market place.
