Abstract (en)
[origin: EP3745075A1] There is provided an indoor heat exchanger that includes a plurality of flat tubes capable of suppressing dispersion of dew condensation water, and an air conditioning apparatus. An indoor heat exchanger (51) to be used in an indoor unit (3) of an air conditioning apparatus (1) includes a plurality of flat tubes (55) that each include a flow channel (55c) for refrigerant and that are vertically juxtaposed, and a plurality of indoor fins (60) joined to the plurality of indoor flat tubes (55). The indoor fins (60) each include a vertically extending continuous portion (64) continuous with portions positioned between the indoor flat tubes (55) vertically juxtaposed. The relation of 4.0 ≤ DP/HT ≤ 10.0 (HT represents the height of each flat tube (55), and DP represents the pitch of the indoor flat tubes (55) vertically juxtaposed) is satisfied.
