摘要： This outdoor unit for an air conditioner is provided with: an outdoor unit main body; a compressor for compressing a refrigerant; an outdoor heat exchanger which exchanges heat between the refrigerant and outdoor air; an outdoor blower which delivers the outdoor air to the outdoor heat exchanger; an external air temperature detection unit which detects the temperature of the outdoor air; and a control unit for controlling operation of the compressor and the outdoor blower. The control unit is provided with: a storage means which stores the external air temperature detected by the external air temperature detection unit when the outdoor unit main body receives an operation stop signal; a temperature determination means which, when the outdoor unit main body receives an operation start signal, determines whether the external air temperature stored in the storage means is less than a temperature threshold value; and an operation timing setting means which, if the temperature determination means determines that the external air temperature is less than the temperature threshold value, selects an operation mode for the compressor on the basis of the external air temperature detected by the external air temperature detection unit after operation of the outdoor blower is restarted.

摘要： Power saving is implemented by cutting power to a compressor driver (31a) and a fan driver (31b) while operating power is kept supplied to a control substrate (307). After the power source to the control substrate (307) is turned on, power is supplied to the compressor driver (31a) and the fan driver (31b). Then, when it is determined that an indoor unit is in operation, the compressor driver (31a) and the fan driver (31b) are operated. Meanwhile, when it is determined that the indoor unit is not in operation, after the lapse of ten minutes or twenty minutes under a predetermined setting, the power to the compressor driver (31a) and the fan driver (31b) is cut. When the operation of the indoor unit is started again, power is supplied to the compressor driver (31a) and the fan driver (31b).

摘要： Plural systems of switching signals are obtained from a single microprocessor for driving a plurality of motors and other apparatuses while achieving effective use of ports of the microprocessor. In principle, three kinds of switching signals based on three-phase are generated in the microprocessor, the three kind of switching signals are converted to six kinds of switching signals in circuits external to the microprocessor, and then the signals are supplied to their respective switching elements in an inverter circuit.
