Outline of Final Research Achievements

CO2 heat pump water heating systems were developed as one of the most important technologies toward low-carbon society. In this research, a method of analyzing the performance of a multi-functional CO2 heat pump water heating system has been established by integrating one-dimensional numerical analysis and three-dimensional experimental analysis. In addition, the performance analysis has been conducted under several conditions and operation conditions have been determined optimally by applying this method.
