Economic and Environmental Evaluation of a Ground-Source Transcritical CO2 Heat Pump for Space Heating and Domestic Hot Water Production
The transcritical carbon dioxide (CO2) heat pump system is a promising technology for space heating and domestic hot water applications. The economic and environmental analysis of the transcritical CO2 ejector heat pump water heater system with a tri-partite gas cooler is researched in this study. A comparison with a traditional electric boiler is provided to illustrate the benefits of the proposed system. The results show that the initial capital cost of the heat pump accounts for 49.2 and 44.3% of the total life cycle cost in Norway and Switzerland, respectively. The sum of the installation and earthwork costs of the heat pump dominates the total initial capital costs. Compared with the electric boiler, the payback period of the proposed system is 10.7 years in Norway and 9.7 years in Switzerland. The heat pump can reduce the electricity and maintenance costs yearly by 64% compared with the electric boiler. The annual CO2 emission reduction of the proposed heat pump system is 73% in the studied locations.
