도시 수자원으로서의 상수.우수, 하수에 대한 열적 포텐셜의 평가

Evaluation on Thermal Potential of Tap Water, Rain Water, Waste Water as City Water System

It has been referred as a problem that heat source/sink is distance from heat demand area in using unused energy. To solve the distance problem in using unused energy, the water from city water system like tap water, rain water, waste water used as unused energy. To survey the potential of the water of city water system, it is developed that the calculation method of the potential using unit method. The amount of theoretical unused energy and energy saving in the Osaka City, Japan were estimated by using that method.
