Abstract
A refrigerant distribution devicesituated in an inlet headerof a multiple tube heat exchangerof a refrigeration system. The deviceincludes an inlet passagethat is in communication with an expansion device. Small diameter nozzlesare disposed within the inlet headerand are in fluid communication with the inlet passage. Capillary liquid nozzlesalso lie within the inlet headerand are in fluid communication with the inlet passage. A two-phase refrigerant fluid in the inlet passagehas a refrigerant liquid-vapor interface. The vapor nozzleshave vapor inlet portsthat lie above the refrigerant liquid-vapor interface. The capillary liquid nozzleshave liquid inlet portsthat lie below the refrigerant liquid-vapor interface. Vapor emerging from the vapor nozzlesblow 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.
