PCT No. PCT/DE93/00670 Sec. 371 Date Mar. 30, 1994 Sec. 102(e) Date Mar. 30, 1994 PCT Filed Jul. 30, 1993 PCT Pub. No. WO94/03262 PCT Pub. Date Feb. 17, 1994.The present invention relates to a process for removing harmful hydrocarbons, particularly plant protective aerosols and vapors, from the fresh air supplied to a vehicle cabin. The loaded fresh air is subjected to a partial condensation with subsequent phase separation. The fresh air is cooled below the dew point of the components to be removed in a type of cold trap. It has a device for collecting and draining the obtained condensate. A standard cooling plant may be installed for providing the cold necessary for partial condensation. If the vehicle is already equipped with an air conditioning system, then the cooling necessary for partial condensation is tapped directly from the air conditioner cycle. It is possible for the fresh air stream to be passed over the evaporator of the air conditioner. The cold air stream present following the removal of the condensate can be warmed in heat exchange with fresh air which is to be cooled prior to its further release into the vehicle cabin. This prevents an overcooling of the vehicle cabin.
