In recent years, the consumption of fossil fuels has increased in Iran and the world, and on the other hand, the trend of increasing the consumption of fossil fuels and their destructive environmental effects, such as air pollution, increasing the earth's temperature, destroying the ozone layer, leads to an increase in the use of renewable and clean energies. A large amount of industrial energy consumption is lost as waste heat. Industrial waste heat recovery using absorption heat transformer (AHT) systems is an effective solution for such problems. Absorption heat transformers are used to improve the temperature of low-temperature heat sources [1]. Absorption heat pump technology has a unique role in optimizing energy structure and sustainable development. Absorption heat transformer systems are equipment that can increase the temperature of low or relatively hot heat sources to more useful temperature levels. The absorption heat transformer is a system that works in a cycle opposite to the absorption refrigeration system to bring these heat sources with low or medium temperature levels to more higher and useful levels. Since the only moving part is the pump system, the system will run quietly and require less maintenance. Other advantages include less mechanical input, long life, and simple design [2]. Therefore, in this work, an attempt has been made to investigate the behavior and performance of single-effect water/lithium bromide (LiBr/H2O) absorption heat transformer systems to optimize in terms of thermodynamics.
