Abstract: A motor vehicle air conditioning arrangement having a heater (H) and an evaporator (V) which are arranged in an air guiding housing (2). Each of the heater and evaporator have a plane that is traversed perpendicularly by air and have an inclined position such that the planes are each arranged at an angle of less than 40° with respect to the horizontal plane (E).

Abstract: In a motor vehicle air conditioning system, comprising a housing, a fan and at least one heating device, the intention is for different heating devices to be able to be fastened to a housing in a technically simple manner with low production costs. This problem is solved in that the at least one heating device is fastened to the housing, in particular exclusively, by at least one adaptor cover.

Abstract: A motor vehicle air conditioning arrangement having at least one heater (H) and at least one evaporator (V) which are arranged in an air guiding housing (2), wherein an inclined position of the heater (H) and evaporator (V) is provided, such that the planes of the evaporator (V) and heater (H), which are traversed perpendicularly by air, are arranged in each case at an angle of less than 40°, in particular of less than 30°, with respect to the horizontal plane (E).

Abstract: The invention relates to a method and system for controlling a compressor in a refrigerant circuit of an air-conditioning system of a motor vehicle. The instantaneous load torque is determined and compared with a maximum limiting torque prescribed by an engine controller, and the compressor is controlled depending on the comparison value resulting therefrom. In order to avoid complete shutdown of the compressor, the instantaneous load torque is represented as a function of variables, such as compressor speed and high pressure of the refrigerant, and, using an inverted function belonging to this function, a control signal for the compressor, for example, a set-point value for the high pressure of the refrigerant, is determined as a function of the maximum limiting torque and employed to control the compressor.
