Vehicle interior heating system

摘要

The heating system for the interior of a vehicle, has a heat exchanger (7) to heat the interior for heat exchange between a heating medium and the air blown into the vehicle interior. A heating medium circuit (4) recirculates the heating medium, heated by the motor (2), between the motor (2) and the heat exchanger (7). A second heat exchanger (9), for a heat exchange between the heating medium and air blown into the vehicle interior, works with a further heating medium circuit (5), heated by the motor (2), between the motor (2) and the second heat exchanger (9). An additional heater (6) heats the medium. The first medium circuit (4) has a lower flow resistance than the second circuit (5). The additional heater (6) is in the first circuit (4).
