In this paper most significant thermodynamic parameters of R125, based on the propenles data presented in [1, 2]. will be examined and compared with those one of RS02. In fact, after the UNEP ~ontreal Protocol, at the present time the manufacturers and researchers have selected R1 25 as more probable long term substitute of R502 in refrigerating vapor compression plants operating with cold ambi...

The present work elaborates the process design methodology for the evaluation of the distillation systems based on the economic, exergetic and environmental point of view, the greenhouse gas (GHG) emissions. The methodology proposes the Heat Integrated Pressure Swing Distillation Sequence (HiPSDS) is economic and reduces the GHG emissions than the conventional Extractive Distillation Sequence (...

Considering lifecycle cost analysis during the design phase of thermal systems gives the design effort more worth. Furthermore thermodynamic exergetic optimization is a proven useful method for determining the most lifecycle cost optimal design of thermal systems for given thermodynamic constraints. The most thermodynamic efficient heat exchanger design basing on first law analysis may not be t...

Düşük sıcaklığa sahip bir jeotermal kuyu destekli ORC çevrimi incelenmiş ve çalışma akışkanı olarak n-pentane seçilmiştir. N-pentane akışkanının kazanda direkt ısıtılması işlemi için Terminol 72 ısı transfer yağı Yağ ısıtılmadan önce, kuyudan alınan düşük kaynak ısısı ile ön ısıtılmaya tutulmuştur. Jeotermal sıcaklığı 80℃ olan kaynağına sıcaklık artışı sağlanarak incelenmiştir. Bu çevrimde türb...
