Numerical analysis of selected evaporative exchangers with the Maisotsenko cycle

This paper describes numerical modeling of heat and mass transfer in five different exchangers utilizing the Maisotsenko cycle for indirect evaporative cooling. For this purpose, numerical models are developed based on the modified e-NTU method to perform thermal calculations of the indirect evaporative cooling process, thus quantifying overall performance of considered heat exchangers. Numerical simulation reveals many unique features of considered devices, enabling an accurate prediction of their performance. The results of computer simulation showed high efficiency gains that are sensitive to various inlet conditions, and allow for estimation of optimum operating conditions, including suitable climatic zones for the proposed unit using.
