摘要： In a communication control system for an air conditioner including an outdoor unit, plural indoor units and control equipment such as a remote controller, etc. which is connected to each indoor unit through a communication line, data communication being carried out between each indoor unit and the control equipment through the communication line, each indoor unit is equipped with a communication control device having a power source circuit 59 to which a power source voltage is supplied from a main power source, a communication superposing circuit for superposing communication data on the power source voltage, a transistor 54 for ON/OFF-controlling the supply of the power source voltage from the main power source to the communication superposing circuit, and a polarity coincidence circuit 63A that passes the output of the communication superposing circuit therethrough to the communication line and depolarizes the power source voltage from the external. Even when an indoor unit functioning as a power supply source cannot supply power due to some trouble, another indoor unit is automatically selected as a power supply source so that the power supply operation can be continuously carried out in the air conditioner.

摘要： In an inverter driving circuit and an air conditioner having the same, the circuit elements constituting the inverter driving circuit are arranged and connected through wirings along a power supply path so that those circuit elements and wirings which are located at the front stage of a noise filter are spatially separated from those circuit elements and wirings which are located at the rear stage of the noise filter. A power source of a controller for the inverter driving circuit is supplied with an alternating power from a neutral point and one of three phases (R,S,T) of the noise filter, and a high-frequency noise occurring in a transistor module is intercepted by a smoothing circuit and a rectifying circuit, so that the noise contamination into the controller can be prevented. The voltage to be supplied to the controller may be a low voltage.
