Microchannel heat exchanger including multiple fluid circuits
First Claim
1. A microchannel heat exchanger comprising:
- a plurality of microchannel tubes including a first set of microchannel tubes and a second set of microchannel tubes;
a first circuit including the first set of microchannel tubes, wherein a portion of a first fluid flows through the first set of microchannel tubes and exchanges heat with a second fluid;
a second circuit including the second set of microchannel tubes, wherein a remainder of the first fluid flows through the second set of microchannel tubes and exchanges heat with the second fluid, wherein the first fluid from the first circuit and the first fluid from the second circuit combine into a common flow; and
the microchannel heat exchanger includes a first header, a second header, and the plurality of microchannel tubes extend therebetween, wherein the first fluid from the first circuit and the first fluid from the second circuit combine into a common flow after exiting the plurality of microchannel tubes, the first header, and the second header.

Abstract
A microchannel heat exchanger includes a plurality of microchannel tubes including a first set of microchannel tubes and a second set of microchannel tubes. A first circuit of the microchannel heat exchanger includes the first set of microchannel tubes, and a portion of a first fluid flows through the first set of microchannel tubes and exchanges heat with a second fluid. A second circuit of the microchannel heat exchanger includes the second set of microchannel tubes, and a reminder of the first fluid flows through the second set of microchannel tubes and exchanges heat with the second fluid. The first fluid from the first circuit and the first fluid from the second circuit combine into a common flow.

2. A refrigeration system comprising:
-
a compressor for compressing a refrigerant; a condenser for cooling the refrigerant; an expansion device for expanding the refrigerant; and an evaporator for heating the refrigerant, wherein at least one of the condenser and the evaporator is a microchannel heat exchanger, the microchannel heat exchanger including a plurality of microchannel tubes including a first set of microchannel tubes and a second set of microchannel tubes, wherein a first circuit includes the first set of tubes and a second circuit includes the second set of tubes, wherein a portion of the refrigerant flows through the first set of tubes and exchanges heat with air, a remainder of the refrigerant flows through the second set of tubes and exchanges heat with the air, and the refrigerant from the first circuit and the refrigerant from the second circuit combine into a common flow, further including a distributor, the distributor in communication with the compressor, and the distributor splitting the refrigerant from the compressor into the portion and the remainder before the portion flows through the first set of tubes and the remainder flows through the second set of tubes. - View Dependent Claims (3, 4, 5, 6, 7, 8)
