AIR CONDITIONING SYSTEM(except Automatic Air Conditioning System) SYSTEM DESCRIPTION

  1. GENERAL

    The air conditioning system has the following controls.

    Control

    Outline

    Manual Control

    Damper positions and blower speed are adjusted automatically according to the operation of switches such as the temperature control switch, blower switch, mode control switch and inlet control switch.

    Compressor Control

    Through the calculation of the target evaporator temperature based on various sensor signals, the air conditioning control optimally controls discharge capacity by regulating the opening extent of the compressor solenoid valve.

      The size of each circle ○ indicates the ratio of airflow volume.

  4. COMPRESSOR (w/ Cooler System)

    A rotary vane type compressor with magnet clutch is used.

  5. NO. 1 COOLER THERMISTOR (w/ Cooler System)

    The No. 1 cooler thermistor detects the temperature of the cool air immediately after the evaporator in the form of resistance changes, and outputs it to the air conditioning control assembly.

  6. BLOWER MOTOR

    The blower motor with fan sub-assembly has a built-in blower controller, and is controlled using duty control performed by the air conditioning control assembly.

  7. BLOWER RESISTOR

    The blower resistor controls the blower motor with fan sub-assembly based on changes in the signal sent by the air conditioning control assembly.

  8. THERMISTOR ASSEMBLY

    The thermistor assembly detects the outside temperature based on changes in the resistance of its built-in thermistor and sends a signal to the combination meter assembly.

  9. PRESSURE SWITCH (w/ Cooler System)

    When a refrigerant pressure malfunction is detected, the pressure switch suspends A/C on signals sent from the air conditioning control assembly to the ECM and cuts the current to the magnet clutch to stop the compressor.
