ICL-BROAD - Technology using (exhaust) heat-source directly into absorption chillers, takes-up fuel-efficiency to more than 60 to 65 % of the power-generation equipment. In many cases by using engine jacket-water-heat when (tri-energy) is added fuel-efficiency is being enhanced to more than 80 % (percent).
