The present invention relates to an arrangement for cooling a cab (4) in a vehicle (1). The arrangement comprises a compressor cooling installation (8) situated externally to the cab (4), a first heat transfer system (14) and a second heat transfer system (20). The compressor cooling installation (8) comprises a line circuit (9) with a circulating refrigerant, an evaporator (13) in which the refrigerant is intended to be vaporised, and a condenser (11) in which the refrigerant is intended to condense. The first heat transfer system (14) comprises a line circuit (15) with a circulating coolant which is intended to be cooled by the refrigerant in the evaporator (13) and to release cold in a heat exchanger (17) which is situated in the cab (4). The second heat transfer system (20) comprises a second line circuit (21) with a circulating coolant which is intended to absorb heat from the refrigerant in the condenser (11) and to release heat in a radiator (23) which is situated in a region (A) in the vehicle (1). |
