Abstract: A system with an internal combustion engine which has a heat transfer circuit, a fuel cell and a climate control unit which is accommodated in the heat transfer circuit of the internal combustion engine. The system has a heat transfer arrangement for transferring the exhaust heat of the fuel cell to the heat transfer circuit and a bypass for bridging a segment of the heat transfer circuit which runs through the internal combustion engine so that, in the bypassed operating state, an isolated circuit is formed. In stationary operation, this enables an optimized operating mode since the internal combustion engine is no longer heated and the exhaust heat of the fuel cell is fully available for heating purposes.

Abstract: A climate control device for stationary control of the climate in a motor vehicle has a heat pump circuit with a first heat exchanger for taking up ambient heat and a second heat exchanger for discharging heat into the vehicle interior and an electrically or mechanically drivable compressor which is located in the flow direction of the heat pump circuit between the first and the second heat exchanger, and a booster set for producing electrical or mechanical power, the electrical or mechanical power being used at least in part to drive the compressor. In addition, there is a third heat exchanger by which the exhaust heat of the booster set is transferred to the heat pump circuit. In this way, good efficiency is ensured for the climate control device in heating operation in stationary operation.

Abstract: An air-conditioning system for a motor vehicle has a coolant circuit which comprises an electrically driven compressor, a condenser, an expansion valve and a latent cold holdover. Heat extracted from the latent cold holdover by the coolant circuit. This is referred to as charging the latent cold holdover. In addition, an air cooling mechanism is provided that extracts heat from the air and is fed to the latent cold holdover. The air-conditioning system can thus be particularly compact and effective as an air-conditioning system for operation in a stationary vehicle.

Abstract: 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.
