Exergetic optimization of absorption chillers – A case study
Case 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.

Thermoeconomic Optimization of Absorption Chiller Cycle [PDF]
Linköping Electronic Conference Proceedings, 2011 In this paper, absorption chillers are modeled as four heat sources: the generator, the evaporator, the condenser, and the absorber and thermoeconomic issues are examined using the available relations. In order to simplify the calculations, all processes are assumed to be reversible.
