Abstract
A header tube assembly is disclosed and can include an outer tube, an inner tube, and a flow valve. Each of the outer and inner tubes can include an open end and a closed end, as well as a plurality of apertures extending through a sidewall of the outer tube and inner tube, respectively. The apertures of the inner tube can permit a flow of refrigerant between an internal volume of the inner tube and a gap between the inner and outer tubes, and the apertures of the outer tube can permit a flow of refrigerant between the internal volume of the outer tube and a plurality of refrigerant circuits in a heat exchanger. The flow valve can be configured to selectively prevent refrigerant from flowing between the gap and the open end of the outer tube, depending on a direction of refrigerant flow through the header tube assembly.
