PURPOSE:To prevent a mix door from swinging by connecting a temperature sensor to the mix door control circuit in nonoperation mode and the mix door opening adjusting fixed resistor to it in operation mode. CONSTITUTION:A temperature sensor 40 located at the upper side of an evaporator permits one end to be grounded to the mobable contact 311 of a change-over contact 31 and the other end to be grounded. A fixed contact 312 is connected to the fixed contact 321 of a change-over contact 32 and a fixed contact 313 is connected to a compressor control circuit 33. A contact 331 which turns on by the output of this circuit 33 is connected to a relay 34 which drives an electromagnetic clutch control contact 341. The fixed contact 322 of the change-over contact 32 is grounded through the mix door opening adjusting fixed resistor 35 and the mobable contact 323 is connected to the mix door control circuit 5 through a solar radiation sensor 36, atmospheric sensor 37, and inner air sensor 38. The control circuit 5 is connected to the actuator 11 of a mix door 10. |
