title = "Design optimization ofmicrochannel heat exchangerswith variable geometry fornatural refrigerants",
abstract = "Air-to-refrigerant microchannel heat exchangers (MCHXs) are now extensively used instationary heat pumping applications. MCHXs with variable tubes, ports and fins have shown great material saving potential compared to the conventional uniform geometry designs. There is continued interest in natural working fluids such as carbon dioxide (CO2), due to various regulations on reduction in greenhouse gas emissions. In this paper, a validated variable geometry MCHX model is used to minimize the material cost and envelope volume ofa R290 automotive MCHX condenser and a CO2 gas cooler. The preliminary optimization results show potential for 35 percent material reduction and 43 percent reduction in heat exchanger envelope volume for the same heat capacity. The presented resultswill help researchers and engineers in optimizing MCHXs foruse with natural working fluids and other refrigerants.",
