Abstract

In this study, Engineering Equation Solver (EES) program was used to predict the performance of an Absorption Heat Transformer(AHT). AHTs have potential in the use of low-level heat sources such as industrial waste heat. low-level heat sources can be raised to high-level heat sources through the cycle of the ATHs.The Performance modelling of a double-effect AHT in this study uses LiBr-H2O as the working solution. The concentration of this working solution ranges from 57.9% to 61.9%. The components of the AHT include absorber, generator, condenser, evaporator and solution heat exchanger. The temperature of the cooling water is 25°C and the temperature of the water used as the low-level heat source is 90°C. This lowlevel heat source can be transformed to steam at 120°C in the Absorber.
