Patent ID: 7258605

Claim:
A heating system for a vehicle, the heating system comprising: a heating air blower for generating a heating air stream to be introduced into the interior space of the vehicle; a heater comprising a heating burner supplied with fuel and combustion air for burning a fuel/air-mixture and generating heat; a heat exchanger arrangement for transferring said heat to the heating air stream being delivered by said heating air blower; a heating air stream temperature sensor arrangement for generating an output linked with the temperature at which the heating air stream heated by said heater is discharged; a mixing arrangement for setting an outside air/ambient air ratio of the air to be fed to said heat exchanger arrangement; an outside temperature sensor arrangement for generating an output linked with an outside temperature; and a control arrangement for controlling said mixing arrangement to set an outside air/ambient air ratio on the basis of an output of said outside temperature sensor arrangement and to set the heat output of said heater on the basis of the output of said heating air stream temperature sensor arrangement.
