Summary:PROBLEM TO BE SOLVED: To prevent erroneous determination about presence/absence of a person in a room.SOLUTION: When a person is absent in a room (10), an air conditioner (20) stops an air conditioning operation temporarily. During the temporary stop of the air conditioning operation, when at least one of human detection sensors (50) of each indoor unit (40) starts to sense presence of a person, an indoor control unit (45) of an indoor unit (40a) acquires integrated sense time by integrating the time in which presence of a person is sensed for each human detection sensor (50). When one of the integrated sense time for each human detection sensor (50) reaches a reference value (T2) before predetermined time (T3) elapses, an outdoor control unit (37) restarts the air conditioning operation. 【課題】室内の人の存在の有無の誤判断を防止する。【解決手段】室内（10）の人が不在の場合、空気調和装置（20）は空気調和運転を一時的に停止する。空気調和運転の一時停止中に、各室内機（40）の人感センサ（50）のうち少なくとも１つが人の存在を感知し始めた場合、室内機（40a）の室内制御部（45）は、人の存在を感知した時間を人感センサ（50）毎に積算して積算感知時間を求める。人感センサ（50）毎の積算感知時間のいずれか１つが、所定時間（T3）が経過するまでに基準値（T2）に達した場合、室外制御部（37）は空気調和運転を再開させる。【選択図】図４
