ABSTRACT:
System and method for controlling flow rate of a fluid through a tube of a heat exchanger, such as through condenser or evaporator tubes disposed within a respective condenser or evaporator in a refrigerator. Flow direction of fluid through the tube is reversed, e.g. by way of a directional control valve, which can move a brush disposed within the tube therethrough, to automatically clean the same. The system and method is capable of increasing the flow rate of the fluid through the tube at or during the flow directional change, to ensure, e.g., that a minimum velocity required to move the cleaning brush through the tube is reached.
