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.
