A simulation study of several schematic models of both water- and air-cooled single-effect LiBr—H2O absorption chillers energized by a high-potential, low-temperature (73 °C) geothermal source has been carried out using IPSEpro refrigeration software package. All the simulated models were validated against a lithium bromide—water pressure—temperature DÜhring chart. The results obtained show that when the coefficient of performance, heat input into the generator, and cooling mass flowrates are fixed, the cycle parameters are highly affected by variation of the coolant temperature. This information will be useful to designers of absorption refrigeration systems.
