PURPOSE:To minimize the generation of a white fog and an outflow of the chill through a flowout hole by a method wherein when the cooling capacity of a heat exchanger is reduced by sensing, the degree of cooling in a fresh air intake state of a distributor of an air conditioning unit, said distributor is controlled into an internal air intake state. CONSTITUTION:A fan 3 is actuated by switch 17-on to permit air to be supplied into a car room. When a compressor switch 16 has been turned off by that time, contacts of relays 20 and 21 close and an electromagnetic solenoid 15 is manually closed and opened by means of an inside-outside air switch 18 allowing an inside-outside air door 2 to be opened in the direction of an internal air intake port 1b and fresh air intake port 1a. When the compressor switch 16 is turned on, a control device 13 is actuated by a detector 14, and then an input 20 a is turned off, thereby the output of a relay 20 being turned on allowing the output of a relay 21 to be turned off to close the contact to cause the solenoid 15 to be deenergized to provide the internal air intake. Consequently, the inside-outside air door is linked to the compressor 90 that the internal air intake may be effective instead of the configuration of external air intake provided that the compressor is off, and external air intake is effective only when said compressor is on. |
