Investigation the effects of different heat inputs supplied to the generator on the energy performance in diffusion absorption refrigeration systems

This study aims to investigate experimentally the effects of three different heat inputs supplied to generator on the energy performance of the diffusion absorption refrigeration system. To achieve this goal, a conventional diffusion absorption refrigeration system, in which electrical resistance as heat input is employed, is taken a model, which is experimentally scrutinized under different heat inputs, 62, 80 and 115 W, but at the same ambient temperatures and the same filling rate of three-component working fluid. In the analyses, the energy losses rejected to ambient from rectifier, condenser, absorber, solution heat exchanger as well as other components such as solution tank and pipes, the energy gain by evaporator and also energy performance is investigated. While the highest energy performance is calculated for DAR-62 W system as 0.36, the lowest energy performance is calculated for DAR-115 W system as 0.30.
