Claim 5:
6. A heat exchanger comprising:
a distributor; and
a plurality of heat transfer tubes connected in parallel with each other with respect to the distributor,
the plurality of heat transfer tubes including a first heat transfer tube, and a second heat transfer tube disposed below the first heat transfer tube,
each of the first heat transfer tube and the second heat transfer tube being configured as a flat tube, and
an internal pressure loss of the first heat transfer tube being smaller than an internal pressure loss of the second heat transfer tube,
the heat exchanger further comprising a third heat transfer tube connected in series with the first heat transfer tube and the second heat transfer tube via the distributor, wherein
the internal pressure loss of the first heat transfer tube is smaller than the internal pressure loss of the second heat transfer tube, and is greater than an internal pressure loss of the third heat transfer tube.
