AIR CONDITIONING SYSTEM


  1. CONSTRUCTION


    1. A front air conditioning unit that is compatible with left and right independent temperature control is used.

    2. An inside-and-outside dual air layer type air conditioning unit is used on LHD models. This type of air conditioning unit introduces outside air to the upper side and circulates inside air to the lower side, thus achieving anti-fogging performance and ventilation loss reduction.

    3. A Beneficial Refrigerant Stream (BRS) type evaporator is used on models with a 2GR-FE engine.

    4. A cold storage evaporator is used on models with a 2AR-FE engine. The cold storage evaporator with built-in cold insulator uses the cold energy accumulated in the cold insulator to blow cool air inside the vehicle when the engine is stopped according to the stop and start system. As a result, engine restarts according to requests from air conditioning control have been suppressed.

      Tech Tips

      If the cold insulator is not cooled, air blown by the system cannot be cooled.

    5. A Straight Flow Aluminum-II (SFA-II) heater core that is compact and offers advanced performance is used.

    6. A compact wide-angle high flow defroster that gives the defroster nozzle assembly inner wall a radial shape is used to ensure superior defroster performance.
