During the past decade, there has been unprecedented research interest in v
apour-absorption cycle refrigeration and heat pumping driven by the need to
reduce CO2 emissions related to process and comfort cooling. This paper re
views some recent innovations in vapour absorption-cycle technology, with p
articular emphasis on the cycle design and fluid selection. The operation a
nd design of innovative cycles are described as well as the latest research
in working fluids. (C) 2000 Published by Elsevier Science Ltd. All rights
