ABSTRACT

This paper provides an evaluation of the potential for use of brazed aluminum condensers in residential air-conditioning systems. Analysis was done to compare the performance of a brazed aluminum condenser with a presently used 2-row finned tube condenser having 7.0 mm diameter tubes. The comparisons were made for 1-row brazed aluminum designs using 3 × 16 mm or 2 × 20 mm cross-section tubes, whose condensing performance has been measured. Used with a commercially available fin geometry at 26 fins/in, the 3 × 16mm tube design will provide 35% material weight reduction and 15% lower pressure drop, relative to the 7.0 mm round-tube heat exchanger. No cost reduction is predicted. The predicted air-side performance was verified in wind tunnel tests. An advanced fin design having a smaller louver pitch will use 22 fins/in, and provide a 55% material cost reduction. The advanced fin geometry has 8.1 mm high fins, 12 louvers and 1.0mm louver pitch. If a tube having 2.0 mm minor diameter is used, greater air pressure drop reduction will be achieved, but at the expense of material savings.
