Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 150 words
A heating and/or air conditioning plant for motor vehicles with at least one blower (6) for controlling the quantity of air fed to the interior (44) of the motor vehicle and with at least one heatable heater (10) for controlling the temperature of the air fed to the interior (44) of the motor vehicle and with, disposed in the airstream to the interior of the motor vehicle, air distributing and air guiding elements for adjusting the temperature of the air fed to the driver's and passenger's sides, characterised in that at least one odour filter (5) is provided in the airstream to the vehicle interior (44) upstream of the fan (6) and in that at least one bypass (7) is provided to bypass the odour filter (5) and to feed air back from the vehicle interior (44) through a duct (54) which is connected upstream of the odour filter (5).
Claim 2
Dependent Claim 34 words
A heating and/or air conditioning plant according to Claim 1, characterised in that a vaporiser (8) is disposed downstream of the odour filter (5) and the blower (6) and upstream of the heater (10).
Claim 3
Dependent Claim 45 words
A heating and/or air conditioning plant according to Claim 1 or 2, characterised in that the odour filter (5) is constructed as a segment of a hollow cylinder coaxial with the fans (6) and is disposed in the intake zone (31) of the blower (6).
Claim 4
Dependent Claim 33 words
A heating and/or air conditioning plant according to one of Claims 1 to 3, characterised in that at least one dust filter (2) is provided in the airstream to the vehicle interior (44).
Claim 5
Dependent Claim 25 words

Dependent Claim 55 words
A heating and/or air conditioning plant according to one of Claims 1 to 10, characterised in that in the case of a cooling and/or heating apparatus (56) which is associated with the bottom region (55) of the motor vehicle interior (44), a dust filter (19) is provided in the airstream to the bottom area (55).
Claim 12
Dependent Claim 34 words
A heating and/or air conditioning plant according to Claim 11, characterised in that the dust filter (19) is disposed upstream of a cooling arrangement (56) which contains an evaporator (18) and a blower (17).
Claim 13
Dependent Claim 43 words
A heating and/or air conditioning plant according to Claim 11 or 12, characterised in that to supply air from the motor vehicle interior (44) to the bottom area (55) a duct (57) is provided which is connected upstream of the dust filter (19).
Claim 14
Dependent Claim 36 words
A heating and/or air conditioning plant according to one of Claims 11 to 13, characterised in that air distributing and air guide elements (47, 48, 49) are disposed in the airstream to the bottom zone (55).
