  • Patent number: 8107804
    Abstract: An energy accumulator system for accumulating heat from a heat source for subsequent supply to a heat demand, comprises an energy accumulator having a storage material in a heat-exchange relation with the heat source so as to store heat produced by the heat source. A controller is connected to the energy accumulator to obtain temperature data with respect to the storage material, and to the heat source so as to selectively actuate the heat source. An energy level calculator is associated with the controller to determine a storage capacity in the energy accumulator as a function of temperature data of the storage material. An operation identifier determines when to store energy in the energy accumulator as a function of the storage capacity and of condition data pertaining to the heat source. The controller actuates the energy accumulator and the heat source to store heat in the energy accumulator.

  • Patent number: 7707845
    Abstract: 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.
