PURPOSE:To prevent an outside-air temp. sensor from being affected by the external turbulence due to the preceeding car, by feeding the output of said outside-air temp. sensor into a target room-temp. arithmetic circuit as an air- conditioning control factor through a delay circuit in accordance with a the predetermined output of said outside-air temp. sensor. CONSTITUTION:The signals from a room-temp. sensor, an outside-air temp. sensor, and a solar radiation sensor 11 to 13, and a room temp. setting element 16, are inputted in an air-conditioning control system 15 actuated by a microcomputer. In said system, a target room temp. is operated in a circuit 22, the quantity of blow and the ratio of inside-outside air intake are controlled through drive circuits 23 and 24, the opening of mixed-air door is operated in a circuit 25, and the mixed-air door is controlled through a drive circuit 26. Here, if the output of the outside-air temp. sensor undergoes changes due to the external turbulence of air caused by the exhaust heat of a preceeding car, etc., and the detected value of changes 41 exceeds the preset value, a judging circuit 40 actuates a control circuit 20 to feed the output of the outside air temp. sensor 12 into the target room-temp. arithmetic circuit 22 through the delay circuit 21. Thereby the influence of the outside air turbulence can be prevented with the air conditioning control always maintained in a comfortable condition. |
