Air Conditioning System -- System Description



GENERAL
  1. The air conditioning system has the following features:

    1. In compliance with the temperature set with the temperature control switch, the A/C amplifier calculates the outlet temperature based on the input signals from various sensors. In addition, corrections in accordance with the signals from the room humidity sensor and the water temperature sensor are added to control the outlet air temperature.
    2. Controls the blower motor in accordance with the airflow volume that has been calculated by A/C amplifier based on the input signals from various sensors.
    3. Automatically changes the outlets in accordance with the outlet mode ratio that has been calculated by the A/C amplifier based on the input signals from various sensors.
    4. Automatically controls the air inlet control damper in accordance with the airflow volume that has been calculated by the A/C amplifier.
    5. Based on the signals from the ambient temperature sensor, this control calculates the outside temperature, which is then corrected in the air conditioning amplifier, and shown in the multi-information display in the combination meter.
    6. Turns the rear defogger and outside rear mirror heaters on for 15 minutes when the rear defogger switch is pressed. Turns them off if the switch is pressed while they are operating.
    7. The A/C amplifier automatically controls the air inlets based on the signals from the smog ventilation sensor.
    8. Checks the sensors in accordance with operation of the air conditioner switches.
    HINT:
    The smart connector has a built-in IC that enables communication with the A/C amplifier and servomotor driving and position detection.
    1. The A/C amplifier is equipped with the function of controlling the indicator lighting.
