摘要： A heat exchanger (23) includes a plurality of principal heat exchange sections (51a-51c) and auxiliary heat exchange sections (52a-52c). A first header-collecting pipe (60) includes an upper space (61) communicating with flat tubes (33) of all of the principal heat exchange sections (51a-51c). Each of the auxiliary heat exchange sections (52a-52c) is in series connection to a corresponding one of the principal heat exchange sections (51a-51c). Of tube number ratios of the number of the flat tubes (33) constituting each of the heat exchange sections (51a-51c) to the number of the flat tubes (33) constituting a corresponding one of the auxiliary heat exchange sections (52a-52c), the first principal heat exchange sections (51a) which is the lowermost one has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section (51a) is accelerated during defrosting, thereby shortening the time required for defrosting.

摘要： Provided are a heat exchanger and an air conditioning apparatus with which it is possible to suppress eccentric flow of refrigerant, even when employed under conditions in which the circulation rate varies. A plurality of flat multi-perforated tubes (21 b, 121 b) are connected at different heightwise locations in a first internal space (23a) of a doubled-back header collecting tube (23) of an outdoor heat exchanger (20). For the first internal space (23a), a loop structure is adopted including a first partition plate (51), and first inflow port (41x), a first upper communicating passage (51x), and a first lower communicating passage (51y) for allowing the refrigerant to ascend within a first outflow space (51 a). The first internal space is partitioned by a first flow regulation plate (41), the first partition plate (51), and a first blocking plate (61) into the first outflow space (51 a), a first loop space (51b), a first inflow space (61b), and a first ascension space (61a). The refrigerant passage of the flat tube (121b) that is connected to the first inflow space (61b), and a lower communicating port (61x) linking the first inflow space (61b) and the first ascension space (61 a), are arranged so as to not overlap each other.

A heat exchanger (1), in which a large number of plate-shaped fins (21) are attached to outer peripheries of heat transfer tubes (20) through which a refrigerant flows, the heat exchanger (1) being for performing heat exchange with the air. Three rows of heat transfer tubes (20a, 20b, 20c) are arranged along an air flow direction. Among the three rows of the heat transfer tubes (20a, 20b, 20c), an inlet side heat transfer tube in a case of using as an evaporator or an outlet side heat transfer tube in a case of using as a condenser has the smallest diameter. In a case where the most windward side heat transfer tube has the smallest diameter, a tube diameter of the most windward side heat transfer tube is D1, a tube diameter of the middle heat transfer tube is D2, and a tube diameter of the most leeward side is D3, D1

摘要： In a heat exchanger (23), a principal windward heat exchange region (35) includes a principal windward bank portion, a principal leeward heat exchange region (65) includes a principal leeward bank portion, an auxiliary windward heat exchange region (37) includes an auxiliary windward bank portion, and an auxiliary leeward heat exchange region (67) includes an auxiliary leeward bank portion. Each of the principal and auxiliary bank portions is constituted of a plurality of flat tubes. In the heat exchanger (23) functioning as an evaporator, a refrigerant flows sequentially through the auxiliary windward, auxiliary leeward, principal leeward, and principal windward bank portions. In the heat exchanger (23) functioning as a condenser, a refrigerant flows sequentially through the principal windward, principal leeward, auxiliary leeward, and auxiliary windward bank portions. Consequently, the heat exchanger exhibits performance sufficient for functioning as both an evaporator and a condenser.
