Outline

•  Integrated A/C unit adopted.
•  Sub-cooling system to multi-flow condenser adopted.
•  PTC heater adopted. (with PTC heater)
•  Refrigerant pressure sensor adopted in which refrigerant pressure is changed into a linear electric signal and precise information is transmitted.
•  The climate control unit with built-in the display panel is adopted.
•  HFO-1234yf has been adopted as the new refrigerant. HFO-1234yf refrigerant has little effect on global warming. (with HFO-1234yf)
•  The blower fan controller has been adopted.
