Abstract:
A stacking-type header according to the present invention includes: a first plate-shaped unit; and a second plate-shaped unit stacked on the first plate-shaped unit, and having a distribution flow passage, in which the distribution flow passage includes a branching flow passage including: a first flow passage; and a second flow passage, and in which the branching flow passage is smaller in difference in flow resistance between the first flow passage and the second flow passage than a branching flow passage in a state in which a flow-passage resistance in the first flow passage and a flow-passage resistance in the second flow passage are equal to each other, and in a state in which the first flow passage and the second flow passage are point symmetric with each other about the opening port.

Claim (Index 37):
An air-conditioning apparatus, comprising a heat exchanger, comprising:\n the stacking-type header of  claim 26 ; and a plurality of first heat transfer tubes connected to the plurality of first outlet flow passages, respectively, wherein the first plate-shaped unit of the stacking-type header has a plurality of second inlet flow passages formed therein, into which the refrigerant passing through the plurality of first heat transfer tubes flows, wherein the second plate-shaped unit of the stacking-type header has a joining flow passage formed therein, the joining flow passage being configured to join together flows of the refrigerant, which passes through the plurality of second inlet flow passages to flow into the second plate-shaped unit, to cause the refrigerant to flow into a second outlet flow passage, wherein the heat exchanger comprises a plurality of second heat transfer tubes connected to the plurality of second inlet flow passages, respectively, wherein the distribution flow passage is configured to cause the refrigerant to flow out from the distribution flow passage toward the plurality of first outlet flow passages when the heat exchanger acts as an evaporator, and wherein the plurality of first heat transfer tubes are positioned on a windward side with respect to the plurality of second heat transfer tubes when the heat exchanger acts as a condenser.
