Abstract
A vehicle occupant compartment heating system includes a housing having an air inlet side and an air discharge side. A heat exchanger heated by engine cooling water, is mounted in the housing at the air inlet side. Electric heating coils powered by the vehicle current generator are mounted in the housing adjacent the heat exchanger and disposed between the heat exchanger and air discharge side. A blower with a fan is mounted in the housing for drawing air through the housing from the air inlet side to the air discharge side. A controller controls the operation of the electric heating coils to operate the heating coils to provide heat at least until the heat exchanger is heated by the engine coolant.
Claims10
A vehicle occupant compartment heating system comprising:
- a housing having an air inlet side and an air discharge side;
- a heat exchanger heated by engine cooling water mounted in said housing at said air inlet side;
- electric heating coils powered by the vehicle current generator mounted adjacent said heat exchanger between said heat exchanger and air discharge side;
- a blower with a fan mounted in said housing for drawing air through said housing from said air inlet side to said air discharge side;
- and
- a controller for controlling the operation of said electric heating coils to operate said heating coils to provide heat until said heat exchanger is heated by the engine cooling water.
A method for quickly providing heat into a vehicle occupant compartment heated by a heat exchanger mounted in a housing having an air inlet side and an air discharge side and a blower with a fan mounted in said housing for drawing air through said housing from said air inlet side to said air discharge side, the method comprising the step of:
- mounting electric heating coils powered by the vehicle current generator in said housing adjacent said heat exchanger and disposed between said heat exchange and air discharge side;
- and
- controlling the operation of said electric heating coils to provide heat at least until said heat exchanger is heated by the engine cooling water.
