Abstract (en)

The present invention relates to air conditioners with reduced power consumption in standby mode. The Outdoor unit of the air conditioner is provided with a zero crossing circuit connected to a power source from one end and connected to the relay circuit from the other end. The power source of the zero crossing circuit 130 is cut-off by deactivating the RY-AC and RY-PWR during standby mode to reduce power consumption. The air conditioner 100 includes another microprocessor-controlled relay (RY-C) at the outdoor unit 120 connected between a terminal (T1') and a compressor, which is kept "OFF" during standby mode to reduce the power consumption. The air conditioner 100 further includes a low power, high impedance switching transformer connected between a terminal (T2') and the terminal (T1') for reducing a standby current by increasing resistance of the switching transformer that in turn results in reduced power consumption.
