PURPOSE:To prevent an air conditioning control system from being disturbed due to the temporary disturbance when a window opens and closes by detecting the opening and closing of the window and holding the control output of the control circuit for a preset time. CONSTITUTION:All is controlled by the output of a control circuit 1. The input sources are the temperature in a car room from an inner atmosphere sensor 25, the outer temperature from an outer atmosphere sensor 26, and the preset temperature from a temperature setting device 27. These are operation-processed in the control circuit 1 and output to the electromagnetic clutch 5 of transducers 9, 14, 19, and 22. These outputs control modes, amount of air supplying, the ON-OFF of a compressor 4 and set the inside of the car room to the preset temperature. A hold circuit 28 is provided on the output end of the control circuit 1. When an opening and closing detector 30 detects the opening of the window, the output is fixed to the current state for some minutes the state up to this time is continued. That is, a control system is not changed in a short period of time such as fare payment and comfortable air conditioning can be maintained. |
