Recovery of Wasted Heat with Centralized and Distributed Heat Pump Systems

摘要

Large amounts of heat are wasted in power system, industrial, and sewage treatment processes. This heat cannot generally be utilized for several reasons including the low temperatures at which it is available; the non-coincidence or lack of reliability of its availability when needed; its location being distant from locations where usable; and contaminants, corrosives, or hazards associated with it. Heat pump technology coupled with thermal storage offers solutions to many of these impediments. The thermodynamics involved and the recovery potential of central and distributed heat pumps in community energy systems providing heating and air-conditioning for buildings are examined. Basic system considerations are discussed and several approaches are presented to conserve scarce energy resources with such systems. (ERA citation 04:023698)
