Abstract: A preheating apparatus for a vehicle having an operating fluid storage chamber of a first assembly, wherein a first operating fluid for operation in the first assembly is provided in the operating fluid storage chamber, an electric pump, wherein the electric pump is arranged in an external region of the operating fluid storage chamber and of the first assembly, and at least one heat source for supplying heat to the first operating fluid or removing heat from the first operating fluid, wherein the electric pump pumps the operating fluid out of the operating fluid storage chamber to the heat source.

Abstract: An arrangement for heating a motor vehicle interior, especially a truck driver's compartment, a bus interior or the passenger compartment of a passenger car, with a ventilation device (10) for taking in fresh air via a fresh air intake area and for discharging air into the motor vehicle interior, with a heating device (11) for heating of air, and with a warm air line (25) for routing the air which has been heated by the heating device (11) into the ventilation device (10). The warm air line (25) is routed into the fresh air intake area such that the heated air emerging from the warm air line (25) is taken in jointly with the fresh air into the ventilation device (10).

Abstract: A device for air conditioning of a motor vehicle interior, with a refrigerant circuit which has a compressor (21), a condenser (22) and at least one evaporator (30), with a heat exchange medium circuit which has at least one heat source (engine 10, auxiliary vehicle heater 14) and at least one heat exchanger (12, 17). To simplify the system and to accelerate the response behavior when heating and cooling, it is provided that there an evaporator (30) of the refrigerant circuit and a heat exchanger (17) of the heat exchange medium circuit are both located in a reservoir (33) which is suited for selective storage of both heat and cold.
