Abstract
A heat exchanger of a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a plurality of microchannel tubes, where each microchannel tube of the plurality of microchannel tubes is configured to direct refrigerant therethrough, and a plurality of fin sets, where each fin set of the plurality of fin sets is disposed between corresponding adjacent microchannel tubes of the plurality of microchannel tubes. Additionally, each fin set of the plurality of fin sets includes a respective fin density based on a location of the respective fin set along a height of the heat exchanger.
Claims20
A heat exchanger for a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a plurality of microchannel tubes, wherein each microchannel tube of the plurality of microchannel tubes is configured to direct refrigerant therethrough;
- and
- a plurality of fin sets, wherein each fin set of the plurality of fin sets is disposed between corresponding adjacent microchannel tubes of the plurality of microchannel tubes, and wherein each fin set of the plurality of fin sets comprises a respective fin density that is selected based on a location of the respective fin set along a height of the heat exchanger.
A heat exchanger of a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:
- a plurality of microchannel coils arranged along a height of the heat exchanger, wherein each microchannel coil of the plurality of microchannel coils extends along a length of the heat exchanger;
- and
- a plurality of fin sets, wherein each fin set of the plurality of fin sets is disposed between a corresponding pair of adjacent microchannel coils of the plurality of microchannel coils, wherein each fin set of the plurality of fin sets extends along the length of the heat exchanger, and wherein each fin set of the plurality of fin sets comprises a fin density that is selected based at least in part on a respective location of the fin set along the height of the heat exchanger.
A heat exchanger, comprising:
- a first section comprising a plurality of first microchannel tubes and a plurality of first fin sets disposed between corresponding adjacent first microchannel tubes of the plurality of first microchannel tubes, wherein each first fin set of the plurality of first fin sets comprises a first number of fins;
- and
- a second section comprising a plurality of second microchannel tubes and a plurality of second fin sets disposed between corresponding adjacent second microchannel tubes of the plurality of second microchannel tubes, wherein each second fin set of the plurality of second fin sets comprises a second number of fins, and wherein the second number of fins is less than the first number of fins.
