Abstract
An air conditioning system for supplying air conditioned air to a passenger compartment of a motor vehicle has left and right hand side distribution ducts connected to a blower by a common distribution chamber. The blower causes air to flow through the common distribution chamber into the left and right hand side distribution ducts via an air conditioning unit. Each of the distribution ducts includes a distribution valve to vary the flow through the respective distribution duct and through a dump duct that exhausts air outside of the passenger compartment. Each of the dump ducts has the same resistance to flow as the respective distribution duct to which it is connected. The flow from the distribution ducts is adjusted by varying the proportion of air that flows through the cooperating dump duct without affecting the flow from the other distribution duct or requiring the blower speed to be altered.
