A refrigerant distribution device (10) situated in an inlet header (12) of a multiple tube heat exchanger (14) of a refrigeration system (20). The device (10) includes an inlet passage (32) that is in communication with an expansion device. Small diameter nozzles (34) are disposed within the inlet header (12) and are in fluid communication with the inlet passage (32). Capillary liquid nozzles (36) also lie within the inlet header (12) and are in fluid communication with the inlet passage (32). A two~-phase refrigerant fluid in the inlet passage (32) has a refrigerant liquid-vapor interface (38). The vapor nozzles (34) have vapor inlet ports (40) that lie above the refrigerant liquid-vapor interface (38). The capillary liquid nozzles (36) have liquid inlet ports (42) that lie below the refrigerant liquid-vapor interface (38). Vapor emerging from the vapor nozzles (34) blow onto and atomize liquid emerging from the liquid nozzle to create a homogeneous refrigerant that is uniformly delivered to the multiple tubes. The invention also includes a method for delivering a uniform distribution of a homogeneous liquid mixture of liquid and vaporous refrigerant through the heat exchanger tubes.
