  3. MAIN FEATURES


    1. The air conditioning system used on new iQ has the following features:

      High Performance

      • Neural network control is used so passengers can control the air conditioning accurately for maximum comfort (with automatic air conditioning system).

      • A pollen removal type clean air filter is used as the clean air filter.

      • The blower control has 7 levels in manual mode and 31 levels in auto mode for more precise control (with automatic air conditioning system).

      • The cooler compressor assembly has a flow volume sensing mechanism which uses a refrigerant flow volume sensor, oil separator mechanism, variable suction side throttle and solenoid control valve with CS valve. As a result, the cooling efficiency has been improved while simultaneously increasing the power saving ability.

      • The PTC (Positive Temperature Coefficient) heater system is used. This system contains a PTC heater that heats the air that has passed through the heater radiator unit sub-assembly to ensure proper heater performance.

      • While the 1ND-TV engine offers excellent combustion efficiency, it generates less heat. In order to provide adequate heating effect, a combustion type power heater is provided.
      Lightweight A BUS connector with a built-in IC is used in a lightweight wire harness design with a reduced number of wires. The use of this connector means that pulse pattern type servo motors are used.
      Compact

      • The air conditioning unit assembly has been made more compact by incorporating the conventional blower fan unit into the center unit.

      • The air conditioning unit assembly is located in the center area of the instrument panel. This provides sufficient foot space for the front passenger.

      • Thin and compact fan blades are used for the blower with fan motor sub-assembly.
      Others

      The following parts are used to ensure high cooling or heating performance while realizing a compact and lightweight construction.


      • RS (Revolutionary super-slim Structure) type No. 1 cooler evaporator sub-assembly

      • SFA (Straight Flow Aluminum)-II type heater radiator unit sub-assembly

      • MF (Multi-Flow)-IV type cooler condenser assembly

      • Continuously variable capacity type cooler compressor assembly (TSB10C type)
