Exergetic optimization of absorption chillers – A case study

open access: yesCase Studies in Thermal Engineering, 2021
The best way to meet the European Union's energy awareness goals is to use a heat pump/refrigerator that requires renewable energy or waste heat to operate. Absorption machines are often powered by renewable energy or waste heat. This article, it was examined how absorption chillers can be optimized for cooling.
