In this session, four different research and implementation facets towards improving performance and efficiency of heat operated cooling technologies are evaluated. The first author evaluates utilization of ionic fluids in absorption systems instead of traditional salts. The second author introduces new generation membrane-based absorption technology, which utilizes ultra thin absorbent films constrained by highly permeable nanoporous membranes. The third author compares adsorption and absorption cooling technologies and demonstrates a residential trigeneration system using adsorption cooling system. Finally, the last authors present implementation of triple effect and multi-energy chillers.
