Experimental Studies on Influence of Process Variables to the Exergy Losses at the Double Tube Heat Exchanger

摘要

Heat Exchangers are widely used at different applications related with heat science and techniques. Today at the investigation of heat exchanger projection, First Low of Thermodynamics is not anymore sufficient. The reason of this more effective use of heating sources and systems, not the quantity of energy but quality of energy must be taken into consideration. energy transferofmation in theh eat exchangers, in the scope of Second Law of Thermodynamics can be listed in two groups depending on chosen variables for analysis. These are a) entropy based work b) exergy based work. In this study, it is aimed to analysed theoretically and investigate experimentally effect of inlet and outlet temperatures of temperatures differences and flow directions for same path parallel flow and counter path parallel flow by using double tube heat excanger. According to the obtained results, it is aimed to determien necessary information for projection and to bring down to be most economical value of the heat exchanger cost and of energy consumption.
