A refrigeration condenser has at least two serpentine paths of unequal lengths (effected by unequal numbers of loops in the paths) extending between common inlet and outlet ports. By adding this design capability to the conventional equal path length condensers greater design flexibility is provided to permit smaller incremental size changes from conventional equal path length condensers, and allows inlet and outlet ports to be on the same side or on opposite sides without any change in condenser size or performance.
