Example: Heating vehicle interior with high-voltage heater (linear) Z189

684_029

Thermal management coolant pump 2 V618 transports the coolant through coolant changeover valve 1 N632 to high-voltage

heater (linear) Z189. There, the coolant is heated up as required. The heated coolant then enters the heat exchanger for interior

heating 6 and transfers the heat to the air flowing into the vehicle interior. From there, the coolant flows through the heat con-

denser B back to coolant pump V618.

Temperatures of up to approx. 65 °C can occur in the heating circuit.
