HEATER, VENTILATION AND AIR CONDITIONING

id070000700000


Features

•  HFO-1234yf refrigerant has been adopted to the refrigerant system.
•  An electric compressor has been adopted which operates at high voltage.
•  With the adoption of the electric A/C compressor, insulated compressor oil (ND-OIL11) has been adopted.
•  A touch panel climate control unit has been adopted.
•  A heat pump control unit which controls the heater and air conditioner system has been adopted.
•  A cabin preconditioning system has been adopted which can operate the climate control system before driving.
•  LIN communication control has been adopted for control of the air intake actuator, air mix actuator,mode actuator,electric compressor, and the PTC heater.
•  A heat pump system has been adopted to the heater and air conditioner system
•  A PTC heater has been adopted which operates at high voltage.
