Description
Summary:This paper describes numerical modeling of heat and mass transfer in exchangers utilizing the Maisotsenko Cycle for indirect evaporative cooling. For this purpose, numerical models are developed based on the modified ϵ-NTU method to perform thermal calculations of the indirect evaporative cooling process, thus quantifying overall performance of considered heat exchangers. The numerical modeling results have been corroborated against existing experimental data. Numerical simulation reveals many unique features of considered heat and mass exchangers, enabling an accurate prediction of its 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 units. A comparative analysis was performed to analyze which unit obtains the highest efficiency. The results indicated that currently produced cross-flow heat and mass exchanger achieves highest cooling capacity, while the counterflow regenerative unit is characterized with the lowest outlet temperatures.
