A washing machine includes an electric motor developing torque used for wash, rinse and dehydration operations, a current detector detecting current flowing into the motor, and a torque controller performing a vector control for the motor on the basis of the current detected by the current detector so that the torque developed by the motor is optimum for at least each of the wash and dehydration operations.

A leak detection method for electrical equipment provided with an electric motor, includes the step of detecting, during non-energization of the motor, a voltage generated in a voltage-dividing resistor provided between a winding of the motor and ground, thereby detecting leak produced in the motor.

A refrigeration cycle is a closed cycle constituted by a variable power compressor, a four-way valve, an indoor heat exchanger, an expansion valve and an outdoor heat exchanger. Air-conditioned air is supplied from the refrigeration cycle to a plurality of rooms to be subjected to air conditioning through a supply duct at a portion near a supply opening for supplying the air-conditioned air to a corresponding one of the rooms and controls a flow amount of the air-conditioned air supplied from the supply opening. Air is returned from each room to the refrigeration cycle through a return duct. The indoor heat exchanger of the refrigeration cycle has a temperature sensor for detecting the temperature of the indoor heat exchanger. A system controller controls a drive frequency of the variable power compressor of the refrigeration cycle in accordance with a difference between the temperature of the indoor heat exchanger detected by the temperature sensor and a preset temperature of the indoor heat exchanger.
