A climate control system (10) for a cab/berth of a vehicle, comprises a climate control circuit (12) in which a first refrigerant circulates between at least an energy accumulator (20) in which an accumulator refrigerant is in heat exchange with the first refrigerant, a radiator (22) in the cab/berth to adjust a temperature of the cab/berth, and a heat-exchange unit (23). A refrigeration circuit (14) is provided for submitting a second refrigerant to a refrigeration cycle. An evaporation stage (43) is in heat-exchange relation with the heat-exchange unit (23) of the climate control circuit (12) such that the second refrigerant absorbs heat from the first refrigerant. A controller system (50) is powered by an electric power source (A) of the vehicle and selectively actuates the climate control circuit and the refrigeration circuit (14) so as to store cold or hot energy in the energy accumulator (20) when the electric power source (A) is charged, and selectively actuates the climate control circuit (12) to cool the cab/berth with the radiator (22).
