Claim 0:
1. A method comprising:
receiving, by a first inlet of a first microchannel heat exchanger, a refrigerant;
receiving, by a second inlet of the first microchannel heat exchanger, the refrigerant;
directing the refrigerant received by the first inlet through first microchannels of a first tube of the first microchannel heat exchanger to a first outlet of the first microchannel heat exchanger;
directing the refrigerant received by the second inlet through second microchannels of a second tube of the first microchannel heat exchanger to a first outlet of the first microchannel heat exchanger;
receiving, by a first pipe, the refrigerant from the first outlet;
receiving, by a second pipe, the refrigerant from the second outlet, wherein the first pipe is disposed to crisscross the second pipe, and wherein a portion of the first pipe overlaps a portion of the second pipe between the first microchannel heat exchanger and the second microchannel heat exchanger,
preventing the refrigerant received by the first inlet from flowing to the second tube using a first partition;
preventing the refrigerant directed through the first tube from flowing to the second outlet using a second partition;
receiving, by a third inlet of a second microchannel heat exchanger, the refrigerant from the first pipe;
receiving, by a fourth inlet of the second microchannel heat exchanger, the refrigerant from the second pipe;
directing the refrigerant received by the third inlet through third microchannels of a third tube of the second microchannel heat exchanger to a third outlet of the second microchannel heat exchanger;
directing the refrigerant received by the fourth inlet through fourth microchannels of a fourth tube of the second microchannel heat exchanger to a fourth outlet of the second microchannel heat exchanger, wherein the first microchannel heat exchanger is positioned behind the second microchannel heat exchanger along a first direction such that air flowing in the first direction contacts the second microchannel heat exchanger before the first microchannel heat exchanger.
