Abstract
Today, rapid developments are experienced in terms of energy consumption and energy efficiency in air conditioning systems. Among these systems, waste heat and renewable energy sources are used in absorption cooling systems. Although the initial investment cost of this system is high, the operating cost is low due to the use of waste heat. In this study, the effect of generator, condenser, absorber and evaporator temperatures on system performance (COP) in absorption cooling systems operating with single-stage LiBr-H_2 O fluid pair was investigated. The temperature effect was investigated using energy balances with the help of thermodynamic equations. It was found from the results that the system performance (COP) increased with increasing the generator temperature, and the system performance (COP) decreased with increasing the condenser and absorber temperatures. In addition, it was determined that the LiBr-H_2 O solution temperature and concentration changed in the system examined at different generator, condenser, absorber and evaporator temperatures, and crystallization occurred accordingly in some parameters.
