Abstract (en)

[origin: EP3336449A1] A multiple-type air conditioner (100) is provided with a first indoor unit (110A) and a second indoor unit (110B). When the first indoor unit (110A) is stopped and the second indoor unit (110B) operates with a second indoor heat exchanger (111B) functioning as a condenser, the opening degree of a first indoor expansion valve (140A) is increased if the ratio of a difference between a temperature detected by a first heat exchanger intermediate temperature detector (112A) and a temperature detected by a first heat exchanger outlet temperature detector (113A) to a difference between the temperature detected by the first heat exchanger intermediate temperature detector (112A) and the air temperature is greater than a target value, and the opening degree of the first indoor expansion valve (140A) is reduced if the ratio is lower than the target value.
