PURPOSE:To obtain precise operation of an air-conditioner by controlling airflows from blowoff ports on a roof and a floor in proportion to the thermal distribution. CONSTITUTION:Front and rear air-conditioning units 1 and 16 are provided with roof nozzles 7 and 22 and floor nozzles 8 and 23. Signals from thermal sensors 30, 31, and a thermal setter 32 are inputted into a controlling unit 33, and transducers 10, 14, 25, and 28 are operated by a driving circuit 34 for controlling to open and close doors 9, 13, 24, and 27 via power servomechanisms 12, 15, 26, and 29. This construction permits to adjust the air-condition in a car room optionally for uniforming the thermal distribution or lowering the temperature in the upper part in comparison to the lower part, and the thermal distribution in the car room can be maintained properly. |
