Abstract
An air conditioner and a power line communication system high in reliability and free of malfunction facilitates the installation work such as the wiring. The air conditioner for conducting communication through a power line includes a bridge unit connected to at least an outdoor unit through a transmission line, and at least an indoor unit connected from the power line through a blocking filter. A side of the bridge unit far from the outdoor unit is connected between the blocking filter and the indoor unit. The bridge unit subjects a signal from the outdoor unit to spread spectrum modulation and transmits it by superposing the resulting signal on the power line. The superposed signal is received and demodulated by the indoor unit.
