PROBLEM TO BE SOLVED: To restrain power consumption by raising evaporation temperature in a range allowing capability of an indoor unit to be maintained, in a multiple type air conditioner.SOLUTION: An outdoor controller of an outdoor unit 1 calculates a reaching time to a target temperature from a temperature gradient of air suction temperatures of respective indoor units 2 collected at a predetermined time interval, extracts an indoor unit 2a earliest in the reaching time and a second indoor unit 2b latest in the reaching time based on the calculation result, changes a target evaporation temperature in accordance with differential temperatures between a target value and measurement values of the air suction temperatures of the indoor units 2a, 2b, and transmits a control signal for changing the aperture of an electromagnetic proportional valve 21 of the indoor unit 2a to an indoor controller. |
