A combined effect absorption chiller for enhanced performance of combined cooling heating and power systems

Abstract

Most industrial waste heat (e.g. waste heat from engines) is available as two or more heat sources or in a wider temperature range. Additionally, solar thermal energy has a higher harnessing efficiency at low temperatures while its work potential increases with temperature. However, well-established absorption cooling technologies, such as single and double effect absorption chillers, operate in relatively narrow firing temperature ranges. The use of the maximum temperature range of the sources or of multiple sources together increases the energy harnessing efficiency as well as the productivity of the absorption technology.This paper introduces a combined effect absorption cycle that can ut..
