EXERGY TRANSFER COEFFICIENT FOR HEAT EXCHANGER OPERATING BELOW THE SURROUNDING TEMPERATURE
Based on the analysis of exergy transfer process for the heat exchangers operating below the surrounding temperature, the concept of exergy transfer coefficient is put forward firstly and the expressions which involving relevant variables for the exergy transfer coefficient, the heat transfer units number and the ratio of cold to hot fluids heat capacity rate etc. are derived. Taking the parallel flow, counter flow and cross flow heat exchangers as examples, the numerical results of the local and mean exergy transfer coefficients are given. And the results of exergy transfer coefficient for not considering pressure drop are compared with that for considering pressure drop.
