Abstract
A compressed air supply system including a compressor (12), a compressed air line (4) that connects an outlet (3) from the said compressor to an inlet (5) to a first active component (6), and an adjustable fan (13) which is controlled by a control unit and is arranged to generate an air flow intended to cool the said compressed air line (4), and a vehicle comprising such a system.
Claims15
A compressed air supply system comprising:
- a compressor, a compressed air line that connects an outlet from the compressor to an inlet of a first active component, and an adjustable fan that is controlled by a control unit and which is arranged to generate an air flow to cool the compressed air line;
- and
- the control unit is arranged to determine a cooling requirement of the compressed air delivered by the compressor and to generate an activation signal for the adjustable fan when a cooling requirement exists, thereby protecting said first active component against thermal overload resulting from compressed air fed in from the compressor.
A vehicle comprising:
- an internal combustion engine;
- a cooling system coupled to the internal combustion engine;
- an adjustable fan controlled by a control unit;
- a compressed air supply system comprising a compressor, a compressed air line that connects an outlet from the compressor to an inlet to a first active component, the adjustable fan being arranged to generate an air flow intended to cool a radiator forming part of the cooling system and the compressed air line;
- and
- the control unit is arranged to determine a cooling requirement of the compressed air delivered by the compressor and to generate an activation signal for the adjustable fan when a cooling requirement exists, thereby protecting the first active component against thermal overload resulting from compressed air fed in from the compressor.
