In order to assure with simple controlling and rapid adaptation to different temperature conditions an energy-saving adjustment of the temperature of the interior of a motor vehicle, it is possible by means of a single temperature regulator (T)! and through adjustment of the latter to adjust such regulator in a first regulating range, in particular in the range of 0 to 30% of the total regulating range, from a high refrigeration output to a lower refrigeration output independently of the driving motor of the motor vehicle, and to adjust in a final regulating range a useful heat source (EH or DH)! from a lower output of heat to a high output of heat. According to a preferred exemplified embodiment, the first regulating range is separated from the final regulating range by an intermediate regulating range with air-side adjustment in a mixing space (MR)! and/or water-side adjustment in a heat exchanger (WT)!.
Motor vehicle air-conditioning system with temperature adjustment of the interior space via a single temperature regulator between a lower cooling temperature, on the one hand, and an upper heating temperature, on the other hand, by cooling or heating a stream of air fed into the interior space accordingly, whereby by means of adjustment of the temperature regulator in a first regulating range, in particular in the range of 0 to 30% of the total regulating range, a refrigeration unit is adjustable from a high refrigeration output to a lower refrigeration output, and a final regulating range, a useful heat source is adjustable from a lower output of heat to a higher output of heat, whereby the refrigeration unit is operable independently of the motor drive of the motor vehicle and drivable by an electric motor, and the useful heat source is adjustable independently of the cooling circulation of the motor vehicle.
