Abstract
Method for cooling in a motor vehicle comprising: cooling at least the vehicle engine by a liquid-based cooling system in which coolant is cooled by air in a first heat exchange element which is by the vehicle radiator; heating the cab of the motor vehicle by heating air by using a coolant in a separate second cab exchange element and supplying the heated air to the cab by a fan. The second cab heat exchange element is arranged in a separate cooling configuration by which coolant in the second heat exchange element is cooled by air which is thereafter supplied to spaces other than the cab. There are also devices for accomplishing such cooling, such heating, such heat exchange and such supplying of air.
