PROBLEM TO BE SOLVED: To let, in a heating operation, a discharge temperature reach a target discharge temperature speedily in any installation configuration after the heating operation is started.SOLUTION: Outdoor unit control means 200, when performing heating-time initial opening control to maintain the opening of an outdoor expansion valve 24 at a predetermined initial opening for a predetermined time after the point of time when a heating operation starts, sets the initial opening to a first initial opening larger than a third initial opening when an installation configuration input from an installation configuration input part 250 is a first installation configuration, sets the initial opening to a second initial opening smaller than the third initial opening when the installation configuration input from the installation configuration input part 250 is a second installation configuration, and sets the initial opening to the third initial opening when the installation configuration input from the installation configuration input part 250 is the third installation configuration.SELECTED DRAWING: Figure 4 【課題】暖房運転を行っているときに、設置形態の違いに関わらず、暖房運転を開始してから速やかに吐出温度を目標吐出温度に到達させること。【解決手段】室外機制御手段２００は、室外膨張弁２４の開度を暖房運転を開始した時点から所定時間の間、所定の初期開度に維持する暖房時初期開度制御を行うとき、設置形態入力部２５０から入力された設置形態が第１設置形態である場合は、初期開度を第３初期開度より大きい第１初期開度とし、設置形態入力部２５０から入力された設置形態が第２設置形態である場合は、初期開度を第３初期開度より小さい第２初期開度とし、設置形態入力部２５０から入力された設置形態が第３設置形態である場合は、初期開度を第３初期開度とする。【選択図】図４
