PROBLEM TO BE SOLVED: To suppress reduction of an indoor dehumidifying amount, to enlarge a range of room temperature regulation, and to improve comfortability, in a method for controlling an air conditioner. SOLUTION: In dehumidifying operation (or cooling operation) of the air conditioner formed that an indoor heat exchanger for an air conditioner is divided into three heat exchangers and first and second pressure reducers are situated on respective pipes to interconnect in series the division heat exchangers, in case of a difference between a room temperature Tr and a set temperature Tr being high, advance from a step ST1 to a step ST2 is effected and an outdoor pressure reducer between an outdoor heat exchanger and an indoor heat exchanger is throttled and the first and second pressure reducers are brought into a full opening state and their indoor heat exchangers all form an vaporizer. When the more a difference between the room temperature Tr and the set temperature Tr is lower, advance from a step ST3 to a step ST4 is effected, all of outdoor pressure reducers are brought into a full opening state and the first pressure reducer is throttled to a given value, the second pressure reducer is brought into a full opening state and a part of the indoor heat exchangers form a condenser, and a ratio of their vaporizers is increased. Further, advance from the ST3 to a ST5 is effected, the outdoor pressure reducer is brought into a full opening state and the first pressure reducer is brought into a full opening state. The second pressure reducer is throttled to a given value and a ratio of the condensers of the indoor heat exchangers is increased. |
