PURPOSE:To enable the continuation of power supplying for the electronic control part even during the main power source is cut-off and to prevent the designated content of various operation modes from changing of the designation of the titled device by a method wherein a charging battery for the control power supply of a electronic control part is provided in parallel to a main power source circuit of an air conditioner. CONSTITUTION:During the normal operation of a main power source 1, a storage battery 5 is continuously charged, also a electronic control part 6 is operated by the control power supply from said storage battery 5. A contact 2 is closed by the command from said electronic control part 6, while the air conditioning operation is started by driving a compressor motor 3 and a fan motor 4. Although the air conditioning operation is stopped by cutting-OFF said main power source 1, said electronic control part 6 still stores the memory of the previously designated various operation modes by the supply of controlling electrical current from said storage battery 5. Therefore, when said main power source 1 is recovered, the air conditioning operation is started again by the command from said electronic control part 6. |
