Краткое описание

This report investigates a mathematical simulation of heat and mass transfer in a crossflow heat exchanger designed using the Maisotsenko cycle. This heat exchanger has been recently used in air conditioning units by utilizing the benefits of indirect evaporative cooling. A one-dimensional heat- and mass-transfer model is developed to perform thermal calculations of the indirect evaporative cooling process, thus quantifying overall heat exchanger performance. This mathematical model accounts for many unique features of the cross-flow heat exchanger, enabling an accurate prediction of performance. Results of the model show 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.
