Abstract (en)
[origin: WO2008073108A1] A method and apparatus are presented to ensure adequate distribution of a two-phase refrigerant flowing through a plurality of heat transfer tubes of a parallel flow heat exchanger in a generally parallel manner. In several embodiments of this invention, predominantly single-phase refrigerant (liquid for condensers and vapor for evaporators) is tapped and delivered downstream to a location where a predominantly single-phase refrigerant phase is already present, bypassing at least some of the heat transfer tubes. In this manner, the remaining single-phase refrigerant (vapor for condensers and liquid for evaporators) flowing through the heat exchanger core is uniformly distributed amongst a plurality of heat transfer tubes in the next downstream pass.
