PROBLEM TO BE SOLVED: To suppress a decrease of cooling capacity while lowering an input current value of an electrically-driven motor in an air conditioner in which a rotational speed of a compressor driven by the motor is controlled by an inverter. SOLUTION: When an input current value In of an electrically-driven motor 11 becomes larger tan a predetermined set value Iset1, it is controlled so as to lower air supply amount of a blower 3. Thus, a low pressure of a refrigerating cycle apparatus is lowered, and a load torque of a compressor is reduced. As a result, even when the value In is lowered, a rotational speed of the compressor can be maintained without lowering it, and hence a decrease of cooling capacity of the apparatus can be suppressed. |
