Optimization of microchannel heat Exchanger refrigeration system Using computational fluid dynamics In r410a

Abstract

The MCHE Heat Exchanger MCHE has good thermal behavior as newlinecompared to conventional round tube heat exchanger It is used in wide newlinevariety of applications like power production process chemical food newlineindustries electronics environmental engineering waste heat recovery newlinesystem manufacturing industry air conditioning refrigeration and space newlineapplications In the MCHE refrigerant flows through multiple MCHE flat newlinetubes which contain micro channels ports rather than single wall round tubes newlineIt enhances the net heat transfer rate and the overall film coefficient of the newlineMCHE High efficiency of the MCHE enables the heat exchanger to be made newlinein smaller size and light weight When compared to the round tube heat newlineexchanger microchannels ports has higher refrigerant pressure drop across newlineheat exchanger also it has some charge reduction. newlineEven though numeral of refrigerants were used as a refrigerant in air newlineconditioning and refrigeration applications alkyl halide refrigerants that newlinecontain bromine newline newline
