The invention relates to a system (10) for the overall control of heat for the passenger compartment (33) and for the electrical units in a motor vehicle that is completely or partially propelled by an electric engine powered by a battery, including a heat-control fluid circuit (3) coupled to a heating means (27) and/or to a cooling means (4) enabling said fluid to store calories or frigories when the system (10) is plugged into an electrical network outside of the vehicle. Said fluid circuit is capable of releasing calories and/or frigories to the air of the passenger compartment (33), in an alternating manner, either through a heat exchanger (11c, 11f) between the circuit and the air of the passenger compartment, or using a climate circuit (4) forming a heat pump and/or an air-conditioning system. Reference: figure 3.

System for the overall control of heat for electrically propelled motor vehicle

In an air conditioner constructed to pass an air introduced into an air conditioning unit through an evaporator and a heater core both arranged in the unit, cooler pipes for the evaporator and heater pipes for the heater core are arranged to extend from the same side wall of the air conditioning unit.

A device for climate control of a vehicle is provided which includes a coolant circuit in which coolant flows through a compressor, a condenser, and an evaporator; a heat transfer medium circuit in which heat transfer medium flows through a heat source and a heat exchanger; and a heat/cold reservoir in which the evaporator and the heat exchanger are located The device of the present invention provides an improved and comparatively economical approach to climate control in the area of a driver's bed in a motor vehicle interior by, at least in part, using a heating/cooling surface for a driver's bed and/or vehicle interior wall, which is integrated into the heat transfer medium circuit such that the heat transfer medium can flow selectively through the heating/cooling surface, or the heat transfer medium which is conveyed by the heat source can flow through the heating/cooling surface

Device for climate control of a driver's bed

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).

The method involves determining the instantaneous charge state of a thermal energy store (3) in a heat exchanger circuit (4) carrying a thermal bearer liquid and regulating the heating or cooling power extracted from the store accordingly. A user air conditioning demand is fulfilled if it is compatible with the thermal energy store's state of charge, the vehicle's driving state and the heat exchanger circuit parameters, otherwise reduced heating or cooling power is output. An Independent claim is also included for an arrangement for air conditioning a useful space in a motor vehicle.

Air conditioning, especially for electric vehicle passenger compartment, involves meeting demand if compatible with thermal store's charge state, driving state, heat exchanger circuit parameters
