Analysis of recuperative heat exchanger based on heat fluxes exergy

Popis výsledku v původním jazyce

Exergy analysis allows effective approach for evaluation of recuperative heat exchanger behavior in different operation states that respect 2nd thermodynamic law. This approach is based on exergy definition of heat fluxes transferred between cooled and heated air. Exergy analysis allows including and comparing all heat fluxes on common basis respecting losses caused through irreversible heat transfer processes. As an exchanger's efficiency changes it is necessary to define particular parameters mostly influencing it. In this article is presented advanced approach to our previous method, now containing operation and heat transfer parameters. Transferred heat between air streams relay on operation parameters such as different air volume rates of cooled and heated air and temperatures of air streams at inlets. A heat exchanger itself has specific heat transfer parameters, constant one is an area of heat transfer surface and varying is an overall heat transfer coefficient.
