Sažetak
In this paper a multivariate optimization of a heat exchanger with microchannel coil has been done. Multivariate optimization included three geometry parameters of heat exchanger which, as expected, significantly influence hydrodynamic behaviour of the system. One more variable has been included in optimization process to compare gains in the heat transfer due to water inlet velocity change. Data set used for optimization has been numerically acquired and experimentally validated. Air/water side numerical model of heat exchanger composed of flat tubes with rectangular shapes has been used. Objective function that combines heat transfer rate and pressure drops of air and water has been developed and employed for an optimization procedure. Response Surface Method has been applied. Comparison of a results has been made accompanied by the commentaries and final conclusions.
