Abstract: An indoor heat exchanger has a first region including a first refrigerant path and a second region including a second refrigerant path. The first refrigerant path forms a full counter flow portion during a heating operation, and forms a full parallel flow portion during a cooling operation. The second region is configured so that air has a lower flow velocity in the second region than in the first region. During both the cooling and heating operations, the second refrigerant path forms both a partial parallel flow portion and a partial counter flow portion.

Abstract: A gas-side pipe (70) is provided with a header body (71a) extending vertically along a side end portion (32a) of an indoor heat exchanger (32), a vertical tube portion (74) facing the header body (71 a), and a bent tube portion (73) connecting a lower end portion of the header body (71 a) and a lower end portion of the vertical tube portion (74) together. Part of a liquid-side pipe (80) is provided in a space (S1) between the header body (71a), the vertical tube portion (74), and the bent tube portion (73).
