Microchannel heat exchanger air side heat transfer analysis and optimization
Heat transfer simulations in a heat exchanger with the microchannel coil have been done and described in this paper. The aim of this study was to use a previously validated mathematical model and numerical procedure of compact heat exchangers type with straight microchannels and to investigate heat fluxes dependence on different geometry and operating parameters. According to dimensions of the heat exchanger, which is commonly used in HVAC units as a condensing unit, a 3D mathematical model has been defined and solved numerically. The objective function has been developed with selected input parameters of heat exchanger: fin pitch, flat tube transversal row pitch, and air inlet velocity. Response surface methodology has been applied to derive a polynomial function that describes power density change according to three selected input parameters. Finally, the created function has been subjected to genetic algorithm optimization procedure. Optimal setup for a given geometry and operating parameters has been acquired and followed with discussion and conclusions.
