Abstract

PURPOSE:To make the blow off wind temperature constant even when the revolutional number of an engine is varied, by detecting a compressor revolutional number signal of the mix foor hand operation type air conditioner, and comparing it with a set revolutional number signal to control the operation of an electromagnetic clutch. CONSTITUTION:When a F/V converter 3 outputs a signal 3a corresponding to the revolutional number of the compressor 10, a comparator 4 compares it with a voltage signal 5a corresponding to a standard revolutional number and outputs a controlling signal 4a. If the output signal 3a is greater than the signal 5a, a transistor 7 is turned off, the electromagnetic clutch 9 becomes inactive, and the revolutional number of the compressor 10 is lowered, and if it is in the opposite case, the electromagnetic clutch 9 becomes active and the revolutional number of the compressor 10 is increased. As the revolutional number of the compressor 10 can be kept in a certain range by repeating the above operations, the blow off wind temperature of the mix door hand operation type air conditionerer can be kept constant irrespective of the revolutional number of the engine.
