<p>The present invention relates to an arrangement for maintaining a desired operating temperature of a battery (8) in a vehicle (1). The arrangement comprises a cooling system (12) with a circulating coolant. The cooling system comprises a radiator (14) in which the coolant is intended to be cooled, and a heat-transfer region (12a) in which the coolant is in contact with the battery (8). The arrangement comprises also an AC installation with a circulating refrigerant. The AC circuit comprises a first circuit with a first evaporator (21) in which a refrigerant is intended to cool air in a driving cab space (2) of the vehicle (1), and a first condenser (17) in which the refrigerant is intended to release thermal energy. The AC installation comprises a second circuit with a second evaporator (26) in which the refrigerant is intended to cool the coolant in the cooling system (12), and a second condenser (24) in which the refrigerant is intended to warm the coolant in the cooling system (12).</p> |
