PROBLEM TO BE SOLVED: To permit the power-saving operation of an air conditioner while maintaining comfortable property by a method wherein at least one time of changing of a control temperature into a direction, approached to and separated from an outside temperature, is effected when a predetermined time is elapsed after an indoor temperature within a predetermined temperature range is obtained. SOLUTION: When a control temperature, set in temperature fluctuation treatment with respect to a set temperature, is raised stepwisely to a predetermined temperatureΔt1 and, thereafter, a shifting treatment to reduce the control temperature to another predetermined temperatureΔt2 is finished, the initial control temperature in the fluctuation treatment equal to a final control temperature in the shifting treatment is raised stepwisely. When an outside temperature is about 30 deg.C and a set temperature is not higher than about 24 deg.C, the control temperature is raised by about 0.5 deg.C and about 0.75 deg.C than a set temperature during initial about ten minutes and a succeeding about 2.5 minutes, then, the control temperature is raised about 1.0 deg.C and about 1.25 deg.C during subsequent about 17.5 minutes and succeeding about 2.5 minutes while the control temperature is raised by about 1.5 deg.C during the final about 17.5 minutes, however, a temperature changeΔt3 in the total sum of the fluctuation treatment in this case is 1.0 deg.C.
