Abstract:
A refrigerant system comprising:a refrigerant compressor; a flow restriction; an indoor heat exchanger; an outdoor heat exchanger that includes a vapor manifold and a liquid manifold that place said outdoor heat exchanger in series flow relationship with said refrigerant compressor, said flow restriction and said indoor heat exchanger; a circuit-A borne by said outdoor heat exchanger and extending from a vapor loop-A to a liquid loop-A with said vapor loop-A being coupled to said vapor manifold and said liquid loop-A being coupled to said liquid manifold, said circuit-A being distributed to create a greater plurality of inner A-loops and a lesser plurality of outer A-loops and repeatedly transiting between said plurality of outer A-loops to said plurality of inner A-loops, as said circuit-A runs from said vapor loop-A to said liquid loop-A; and a circuit-B borne by said outdoor heat exchanger and extending from a vapor loop-B to a liquid loop-B with said vapor loop-B being coupled to said vapor manifold and said liquid loop-B being coupled to said liquid manifold to place said circuit-B in parallel flow relationship with said circuit-A, said circuit-B being distributed to create a greater plurality of inner B-loops and a lesser plurality of outer B-loops with said liquid loop-A being closer to said vapor loop-B than said vapor loop-A, said circuit-B repeatedly transiting between said plurality of outer B-loops to said plurality of inner B-loops, as said circuit-B runs from said vapor loop-B to said liquid loop-B.
