Abstract (en)

Provided is a heat exchanger with which it is possible to ensure a high enough heat exchange performance by optimizing the heat transfer coefficient and pressure loss of refrigerant by optimizing the configuration of branched circuits, and as well as an air conditioner employing such a heat exchanger. In a fin-tube-type heat exchanger (9) in which HFO refrigerant is employed and the refrigerant is circulated through numerous refrigerant tubes (11) by being branched to and collected from multiple circuits, a maximum number of branched circuits among the numerous refrigerant tubes (11) is six circuits, and, of the total number of the numerous refrigerant tubes (11), the proportion accounted for by a one-circuit portion (13A) and two- and four-circuit portions (13B and 13C) is set within a range from 7 to 30 % in accordance with the capacity of the heat exchanger (9).
