Abstract

The ammonia-water hybrid absorption-compression heat pump (HACHP) is a technology suitable for industrial scale heat pumps in the process industry. A helpful tool in the design of cost effective and low environmental impact energy conversion systems, such as the HACHP, is the application of an advanced exergy-based analysis, comprised of both an advanced exergy, exergoeconomic and exergoenvironmental analysis. Recent studies have presented both the advanced exergy and advanced exergoeconmic analysis of the HACHP. Anexergoenvironmental analysis combines exergy analysis with life cycle assessment to allocate the initial and operational environmental impact to the system components, thus revealing the main sources of environmental impact. The application of the advanced exergoenvironmental analysis improves the level of detail attained.This is achieved by accounting for technological and economic constraints as well as component interdependencies.The advanced exergoenvironmental analysis shows that the highest avoidable environmental impact stems from the compressor, followed by the absorber. Further, it is found that the initial environmental impactof the HACHP is negligible compared to the operational environmental impact.
