Patent ID: 7707845

Claim:
A climate control system for a cab/berth of a vehicle, comprising: an energy accumulator enclosing an accumulator refrigerant; a climate control circuit in which a first refrigerant different from the accumulator refrigerant circulates between at least the energy accumulator in which the accumulator refrigerant is isolated from and in heat exchange with the first refrigerant, a radiator in which the first refrigerant is in heat exchange with a fluid blown in the cab/berth to adjust a temperature of the cab/berth, and a heat-exchange unit; a refrigeration circuit in which a second refrigerant different from the accumulator refrigerant circulates between a compression stage, a condensation stage, an expansion stage and an evaporation stage for submitting the second refrigerant to a refrigeration cycle, the compression stage having at least one electrically powered compressor, and the evaporation stage being in direct heat-exchange relation with the heat-exchange unit of the climate control circuit such that the second refrigerant absorbs heat from the first refrigerant; and a controller system powered by an electric power source of the vehicle and selectively actuating the climate control circuit and the refrigeration circuit so as to store cold energy in the energy accumulator when the vehicle is turned on and charges the electric power source, and selectively actuating the climate control circuit to cool the fluid blown in the cab/berth with the radiator.
