AIR CONDITIONING SYSTEM


  1. CONSTRUCTION


    1. An air conditioning unit that is compatible with left and right independent temperature control is used.(Models with dual zone automatic air conditioning system)

    2. An inside-and-outside dual air layer type air conditioning unit is used. 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.

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

    5. 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.
