英文要約ABSTRACT

In this research, we developed a water source heat pump system and its components that can supply multiple heat demands of heating, cooling and hot water supply, efficiently with energy consumption and cost by utilizing a heat source water supply network using various renewable thermal energies, such as ground , solar, river water heat and etc. This research has two approaches of practicable and leading development, and the development target is reducing initial and running cost by 18% and 20%, respectively. In this fiscal year, we conducted feasibility studies mainly for the purpose of forecasting economic profitability of the developed system, and basic studies on each development item.
As to feasibility study for hospital, compared to the conventional water source heat pump system, the payback time of the developed practicable system was from 11 to 16 years. By the addition of leading development result, the payback time can be reduced to 9 years. In case of a detached house, compared to the conventional decentralized system, the payback time of the developed system was 50 years. On the other hand, it was 3 years compared to the conventional centralized system.
Furthermore, basic studies of each development item were conducted, and we forecasted economic profitability of the developed system. In next fiscal year, the detailed design of each developed equipment and system will be conducted.
