This electric motor control apparatus has an AC power supply, a converter, an inverter, an electric motor, and a control unit. The AC power supply supplies AC power. The converter converts AC power supplied by the AC power supply into DC power. The inverter is connected to the converter and converts DC power converted and output by the converter into AC power. The electric motor rotates using the AC power converted by the inverter. The control unit controls the rotation speed of the electric motor on the basis of the voltage value of the voltage output from the converter and the current value for the AC power converted by the inverter. The control unit reduces the rotation speed of the electric motor if a power value calculated using the voltage value and the current value exceeds a prescribed value.

Abrégé

One embodiment according to the present invention provides an air-conditioning control device that is connected to an air-conditioning apparatus in which a heat medium taken in via a filter as a result of driving a fan is blown out after having undergone temperature control in a heat exchanger to which a refrigerant is supplied. This air-conditioning control device is provided with a control means, a log data acquisition means, and an inspection processing means. The control means performs an inspectional operation on the air-conditioning apparatus while driving the fan with no refrigerant being supplied to the heat exchanger. During the inspectional operation, the log data acquisition means acquires: temperature data indicating the temperature of the heat exchanger as measured by a temperature sensor provided in the vicinity of the heat exchanger; and log data that includes the time at which said temperature was measured. The inspection processing means checks clogging of the filter on the basis of the acquired log data.

An air conditioner according to an embodiment of the present invention has one or more indoor units, one or more outdoor units, an oil level drop detection unit, and a control unit. The indoor units each have an indoor heat exchanger and an indoor expansion valve. The outdoor units each have an outdoor heat exchanger, an outdoor expansion valve, a four-way valve, and a compressor. The oil level drop detection unit detects whether a drop in the oil level of a refrigeration oil has occurred in the compressors while the indoor units and the outdoor units are performing a heating operation. The control unit switches the four-way valve into the state thereof during a cooling operation when the oil level drop detection unit detects the occurrence of an oil level drop in the compressors.
