Abstract

A process for heating the passenger compartment (10) in a motor vehicle, particularly an electric vehicle, having a heating device (12), which is supplied with an air current (40) extracted, via a waste-air duct (11), from the passenger compartment (10). The air current enters into the passenger compartment (10) from the heating device (12) via an intake-duct (13). In order to prevent internal misting of the vehicle's windows, even with a low heating capacity, at least one partial air current (40a), which is branched off from the air current (40) prior to entry into the passenger compartment (10), flows through a sorbent (15) such as zeolite or the like.
