Energy, Technology, and the Environment
Most industrial processes are accompanied by waste heat; and because of environmental and economic concerns, the management of waste heat is being increasingly scrutinized. The major sources and dispersal methods for waste heat are discussed below, and then the environmental impacts of each cooling technique are considered. Cogeneration is included to illustrate the conversion of waste heat into useful energy. A numerical example of a condenser surface area calculation is shown at the end of the chapter.
