Abstract
An air conditioning installation for the cabin of a motor vehicle comprises an air treatment and distribution unit having an upstream chamber containing a fan and a downstream chamber containing distribution valves for distribution of treated air to the cabin. The two chambers are separated by an evaporator, through which air is driven by the fan into the downstream chamber. A collector for recovery of condensates is located below the evaporator and drains to outside the vehicle. The installation includes control means arranged to operate an automatic scavenging cycle immediately prior to the start of a period of air conditioning operation. This cycle consists in closing all the distribution valves and then running the fan for a predetermined scavenging period so as to drive the stale air out of the interior of the unit.
