Abstract
PURPOSE: To provide an air conditioner which keeps air flow constant as well as minimizes air noise by regulating the opening of a control valve to a prenum chamber stepwise according to the opening condition of a plurality of opening/closing valves provided to each exhaust port of the prenum chamber.
CONSTITUTION: With the actuation of an air blower 3, hot air is sent into prenum chamber 5 and then delivered to areas to be air-conditioned through an opening/c closing valve 10. The opening condition of each valve 10 is detected with respetive microswitch 22, while the opening of a control valve 13 is detected stepwise with a microswitch 20. The detection output of each microswitch is inputted to a comparative operation circuit 24 through a counting circuit 23 and a counting circuit 21 respectively and an appropriate voltage according to the diffeence in comparison computed by the circuit 24 is applied to a pulse motor 25. Consequently, the turning angle of the valve 13 is so regulated as to check the change in pressure in the chamber 5. With such an arrangement, a constant amount of hot air can be fed. In addition, concentrated flow of hot air through only some of air conditioning ducts 6 can eliminated, thus minimizing air noise
