An air conditioning system for a preferably air cooled vehicle has a housing having an evaporator, a chamber and at least one blower. The housing, by way of outlet ducts having individually blockable defroster, center and legroom nozzles, is connected with a passenger compartment. By way of a warm air duct having an exhaust gas heat exchanger, the housing is acted upon by warm air, by way of an inflow duct having a fresh air flap controlled by an electric motor, it is acted upon by fresh air, and by way of an inflow duct for circulating air, it is acted upon by air from the interior of the vehicle. In this case, warm air and/or fresh air and/or circulating air, by way of a temperature mixing flap, is guided to a blower, is swirled together and mixed in it, and subsequently by way of the individual outlet ducts, is guided to the passenger compartment. In order to avoid air throughput fluctuations, the fresh air flap is controlled as a function of the driving speed of the motor vehicle, of the position of the temperature mixing flap, of a rotational speed step of the blower and of a switching condition of an electromagnetic clutch of a refrigerant compressor.

Air conditioning system

An air conditioning arrangement for a motor vehicle with an internal combustion engine whose fuel air mixture supply system is equipped with a fuel cut off in the coasting operation, utilizes a switching device which, in the case of a high heat requirement, at least temporarily stops the fuel cut off in the coasting operation.

Air conditioning system for a motor vehicle

In a heating and/or air-conditioning system for a motor vehicle, which has a first drain for rain and washing water and a second drain for the condensation water forming in the area of the evaporator, it is provided that both drains, at least in part, are integrated, specifically separate from one another, into the housing of the heating and/or air-conditioning system.

Heating and/or air-conditioning system for a motor vehicle

So that, in the case of a preferably air-cooled vehicle, the air-conditioning system responds rapidly to changing heated-air temperatures as well as fluctuations in volume, heated air and/or fresh air and/or circulating air or cooled air is together guided to a fan, is swirled together and mixed in this fan and is subsequently, by way of outflow ducts, guided to the vehicle interior. A blow-out temperature sensor arranged behind the fan continuously scans the temperature deviation of the mixed air from the adjusted desired temperature and, as necessary, automatically corrects the position of a temperature mixing flap provided in front of the fan.

Air-conditioning system for an air-cooled motor vehicle

A floor group for a vehicle, especially for a motor vehicle includes a tunnel arranged in the floor center and extending in the vehicle longitudinal direction, whereby power plant parts and at least one line for the heating and/or ventilation of the motor vehicle are provided inside or adjacent the tunnel and the tunnel is closed off in the direction toward the road surface by a cover element. In order to so construct a line for the heating and/or ventilation which is arranged adjacent a tunnel that together with a simple construction it can be assembled and disassembled with low expenditure, the line is construcuted in one piece with the cover element at least over a partial area of its longitudinal extent.
