Refrigerant distribution optimization for microchannel evaporators

/in /by


Microchannel evaporators are being increasingly used in air conditioning and refrigeration systems, since they aid in reducing refrigerant charge, enhancing heat transfer performance, lowering tube-side pressure drop, and reducing system size. However, as with other types of evaporators, microchannel evaporators face the issue of refrigerant maldistribution. This phenomenon leads to unequal superheated vapor at tube exits and prevents optimum utilization of the heat exchanger surface.
