An Estimation of Quantity of Unused Energy of River Water, Seawater and Treated Sewage as Heat Source and Its Availability in Large Facilities

대규모 시설에서 이용가능한 미활용 에너지의 부존량과 그 이용 가능성에 관한 조사연구-하천수.해수.하수처리수를 중심으로

While the demand for energy has shown a sharp increase recently, the supply seems to be limited by the fact that the conventional fossil fuel energy or nuclear energy has its own environmental problems such as, for example, global warming or nuclear waste disposal. To overcome such limited supply of energy, the utilization of natural thermal energy such as river water and seawater as well as treated sewage can be a substantial supplement. The potential use of the unused energy has become more and more feasible these days as the heat pump technology has been advanced. In the present study, the unused energy resources are estimated on regional and monthly basis for each resource by the method proposed here in order to establish the fundamental data for its utilization. The potential use of the unused energy is a1so discussed.
