Abstract

A control system for an air conditioner is configured that can wirelessly transmit control signals, and allow the output power settings of transceiver units arranged in the outdoor unit and indoor units to be reduced. The air conditioner control system includes an outdoor unit transceiver unit indoor unit transceiver units, and a center. The outdoor unit transceiver unit is arranged in an outdoor unit, and transmits and receives control signals. The indoor unit transceiver units are respectively arranged in the indoor units, and transmit and receive control signals. The center wirelessly relays control signals between the outdoor unit transceiver unit and the indoor unit transceiver units.

Claims

1. A control system for an air conditioner comprising:

an outdoor unit transceiver unit that is configured to be arranged in an outdoor unit of the air conditioner, and which transmits and receives control signals;

an indoor unit transceiver unit that is configured to be arranged in an indoor unit of the air conditioner, and which transmits and receives control signals; and

a center that wirelessly relays said transmitted control signals of said outdoor unit transceiver unit to said indoor unit transceiver unit and wirelessly relays said transmitted control signals of said indoor unit transceiver unit to said outdoor unit transceiver unit.

2. An air conditioner which utilizes an external communication network comprising:

an outdoor unit and an indoor unit;

an outdoor unit transceiver unit that is arranged in said outdoor unit, and configured to wirelessly transmit control signals to and receive control signals from said communication network; and

an indoor unit transceiver unit that is arranged in said indoor unit, and which is configured to wirelessly transmit control signals to and receive control signals from said communication network.

3. An air conditioner utilizing an external communication network, comprising:

an outdoor unit transceiver unit arranged in an outdoor unit and which wirelessly transmits and receives control signals; and

an indoor unit transceiver units arranged in an indoor unit and which wirelessly transmits and receives control signals,

said transmitted control signals of said outdoor unit transceiver unit being transmitted wirelessly to said indoor unit transceiver unit via said communication network and said transmitted control signals of said indoor unit transceiver unit being transmitted wirelessly to said outdoor unit transceiver unit via said communication network.
