摘要: Abstract The residual heat or renewable energy can be used to activate a thermodynamic cycle inside transformer by absorption (AHT), in order obtain with higher temperature whole equipment. performance of the AHT is mainly influenced absorber, since useful obtained here at different operating conditions. According this study, split absorber improve because existing processes accordance first and second law thermodynamics. proposal divide transfer area equal sections, where steam supplied strong working solution increased for all diminish irreversibility absorber. With respect basic best results are found when has two COP improved from 0.307 0.415, while ECOP 0.118 0.160, besides reduce up almost 28%.
