Abstract

An outdoor heat exchanger of an outdoor unit includes a main heat exchanger portion and an auxiliary heat exchanger portion. In the main heat exchanger portion, refrigerant path groups are formed. In the auxiliary heat exchanger portion, refrigerant paths are formed. The refrigerant path in the auxiliary heat exchanger portion, which is located closest to the main heat exchanger portion, is connected to the refrigerant path group in the main heat exchanger portion, which is disposed in a region where a wind velocity of the outdoor air passing through the main heat exchanger portion is relatively high. In addition, the refrigerant path is connected to the refrigerant path group. The refrigerant path is connected to the refrigerant path group. The refrigerant path is connected to the refrigerant path group.
