| dc.description.abstract | The energy crisis has gradually become an important issue facing the world. There are limited reserves of coal, oil, natural gas and other resources. Furthermore, fossil-fuel combustion can cause environmental problems such as global climatic changes. In recent years, there has been a growing attention to energy cascade utilization and waste heat recovery. There has also been a recognition that energy and water issues are intertwined. Addressing the shortages of water and energy in an integrated manner is key to economic development and social progress.
Upon the use of once-through cooling water in power plants and industrial facilities, the discharged water may be too hot for immediate discharge to the surrounding water bodies and may cause thermal pollution. This work proposes to extract excess heat from the cooling water leaving the power plant and to effectively use it to drive a heat pump. The net result is the mitigation of thermal pollution and the reduction of external-fuel usage in heat pumps. A theatrical analysis is carried out for the proposed configuration. To illustrate the validity of the recommended system, a case study is solved and a techno-economic analysis is carried out. | en |
