AIR CONDITIONING SYSTEM


  1. OUTLINE


    1. Air Condition System


      1. 4 models are provided: manual and automatic single air conditioning models, and manual and automatic dual air conditioning models equipped with a rear air conditioning unit.

      2. The automatic air conditioning system uses left and right independent temperature control to enhance comfort.

    2. Combustion Type Power Heater (Models with Combustion Type Power Heater)


      1. Depending on the operating condition, the engine coolant temperature remains low, making it difficult to ensure the proper heating effect. Thus, in order to provide an adequate heating effect, a combustion type power heater is provided.

      2. A heater switch assembly (power heater switch) is located in the driver side of the instrument panel.

  3. MAIN FEATURES


    1. The air conditioning system has the following features:

      Item Feature
      High Performance

      • Neural network control is used so passengers can finely control the air conditioning for maximum comfort.*1

      • A pollen-removal type clean air filter, which has a pollen-removal effect, is used.

      • The blower control has 7 steps to allow precise control.

      • A sub-cool accelerator type tube is used to ensure cooling performance.*2
      Lightweight

      • A bus connector with a built-in IC is used in a lightweight wire harness design to allow a reduced number of wires.

      • The use of this connector means that pulse pattern type servo motors can be used.
      Others

      The following parts are used to ensure high cooling performance while achieving a compact and lightweight construction:


      • Semi-center Location Air Conditioning Unit

      • Revolutionary Super-slim Structure (RS) Evaporator

      • Straight Flow Aluminum-II (SFA-II) Heater Radiator

      • Multi-Flow-IV (MF-IV) Sub-cool Condenser

      • *1: Models with automatic air conditioning

      • *2: Models with dual air conditioning or with single air conditioning and cool box, or models for G.C.C. countries except cold area specification models.

    2. Combustion Type Power Heater


      1. While the 1GD-FTV engines offer excellent combustion efficiency, they generate less heat. Therefore, depending on the operating condition, the water temperature remains low, making it difficult to ensure the proper heating effect. Thus, in order to provide adequate heating effect, a combustion type power heater is provided.

      2. This heater system provides a combustion type power heater between the engine and the heater radiator unit sub-assembly. Air and fuel are introduced into the heater's combustion chamber, and a glow plug is used to ignite this mixture. By heating the engine coolant that flows around the combustion chamber, this system ensures the heating effect. The system can be activated or deactivated by turning on or off the power heater switch provided on the air conditioning control assembly.

  4. PRECAUTION


    1. Precaution for Refrigerant HFO-1234yf (R1234yf)


      1. Compatibility


        1. The parts used in the refrigerant cycle, the compressor oil, etc. of the HFO-1234yf (R1234yf) system are not compatible with the conventional HFC-134a (R134a) system.

      2. Always use HFO-1234yf (R1234yf) as the refrigerant.

        CAUTION:


        • Do not charge the system with refrigerant near open flames, as HFO-1234yf (R1234yf) is combustible.

        • When charging the system with refrigerant, make sure the area is well ventilated(especially be careful in areas where the gas can easily accumulate such as underlifts and in garage pits, as the gas is heavier than air).

        • Follow any local regulations regarding combustible gases.

        • Be sure to use a refrigerant recovery unit that is compatible with HFO-1234yf (R1234yf) systems.

        Tech Tips

        The shape of the service port for refrigerant charging has an exclusive design conforming tointernational standards for HFO-1234yf (R1234yf) to prevent improper refrigerant charging.

      3. Compressor Oil


        1. Always use ND-OIL 12 as the compressor oil.

        2. When parts of the air conditioning system are removed, quickly block off any areas that areexposed to the outside air with plugs, vinyl tape, etc., as the oil used for HFO-1234yf (R1234yf) systems absorbs moisture easily.

        3. Do not allow the compressor oil to spray, as the oil used for HFO-1234yf (R1234yf) systemshas harmful effects on acrylic resins.
