Document Type and Number:
WIPO Patent Application WO/2011/005986
Kind Code:
A3
Abstract:
Heating, ventilation, air conditioning, and refrigeration (HVAC&R) systems and heat exchangers are provided that includes fins of differing fin spacing. The hear exchangers includes multiple sets of multichannel tubes (166,168) in fluid communications with each other and fins of different spacing (172,174) may be disposed between each set of multichannel tubes. In one embodiment, a first set of tubes (166) may direct refrigerant from a first manifold (70) to a second manifold (72) and a second set of tubes (168) may direct refrigerant back to the first manifold (70) from the second manifold (72). The fins (172) between the first tubes (166) may have a relatively smaller density (e.g., fewer fins per inch) than the fins (174) between the second tubes (168).
