Abstract
System for ventilating a vehicle cab (1) and a closet (3) for the drying, airing and storage of work clothing. The system is constituted by a fan in the closet (3) and the fan (9) extracts air from the cab (1) through the closet (3). Excess heat from the coolant circuit of the drive engine is utilized as a heat source in the drying of work clothing. Also, the invention can be advantageously used when the cab is occupied overnight.

- (a) a fan (9) operable to cause an air flow from the vehicle cab (1) via an air intake (5) through said closet (3);
- (b) heating device (12) for heating an interior of said closet (3);
- and
- (c) an arrangement (13) for drying clothes in said air flow after said air intake (5) with its associated heating device (12), wherein said fan (9) is operable to cause air to be drawn via said air intake (5) into said closet (3) and through said closet (3) to a region outside said cab (1);
- and
- 2) a valve connecting said heating device (12) to a coolant circuit of an internal combustion engine (18) of said vehicle, said internal combustion engine being operable via the coolant circuit to heat said closet (3).
