1-20. (canceled)
A heat exchanger for a heating, ventilation, and air conditioning (HVAC) system, comprising:
- a first set of microchannel coils configured to fluidly couple to a first circuit of the HVAC system and configured to direct a first flow of working fluid therethrough;
- a second set of microchannel coils configured to fluidly couple to a second circuit of the HVAC system and configured to direct a second flow of working fluid therethrough, wherein the first set of microchannel coils and the second set of microchannel coils are fluidly separate from one another, and wherein the first set of microchannel coils and the second set of microchannel coils are disposed in an alternating arrangement along a length of the heat exchanger such that the first set of microchannel coils and the second set of microchannel coils are interlaced in the heat exchanger;
- and
- an integrated header, wherein a first microchannel coil of the first set of microchannel coils and a second microchannel coil of the second set of microchannel coils are fluidly coupled to the integrated header.
An interlaced heat exchanger, comprising:
- a first set of microchannel tubes fluidly configured to fluidly couple to a first working fluid circuit;
- a second set of microchannel tubes configured to fluidly couple to a second working fluid circuit fluidly separate from the first working fluid circuit, wherein the first set of microchannel tubes and the second set of microchannel tubes are disposed in an alternating arrangement along a length of the interlaced heat exchanger such that the first set of microchannel tubes and the second set of microchannel tubes are interlaced;
- and
- an integrated header, comprising a first passage, a second passage, and a divider extending between the first passage and the second passage to fluidly separate the first passage and the second passage from one another,
- wherein a first microchannel tube of the first set of microchannel tubes is fluidly coupled to the first passage of the integrated header, and a second microchannel tube of the second set of microchannel tubes is fluidly coupled to the second passage of the integrated header.
A heat exchanger for a heating, ventilation, and air conditioning (HVAC) system, comprising:
- a first set of microchannel tubes configured to fluidly couple to a first working fluid circuit of the HVAC system;
- a second set of microchannel tubes configured to fluidly couple to a second working fluid circuit of the HVAC system, wherein the first set of microchannel tubes and the second set of microchannel tubes are fluidly separate from one another, and wherein the first set of microchannel tubes and the second set of microchannel tubes are disposed in an alternating arrangement along a length of the heat exchanger;
- and
- an integrated header, wherein the first set of microchannel tubes is fluidly coupled to a first passage defined by the integrated header and the second set of microchannel tubes is fluidly coupled to a second passage defined by the integrated header, and wherein the first passage and the second passage are fluidly separate from one another.
