<p>An air conditioning system 120 for supplying air conditioned air to a passenger compartment 116 of a motor vehicle 110 is disclosed having left and right hand side distribution ducts 111L, 111R connected to a blower 122 by a common distribution chamber 121. The blower 122 is used to cause air to flow through the common distribution chamber 121 into the left and right hand side distribution ducts 111L, 111R via an air conditioning unit 123. Each of the distribution ducts 111L, 111R includes a distribution valve 130L, 130R used to vary the flow through the respective distribution duct 111L, 111R and through a dump duct 112L, 112R that exhausts air outside of a passenger compartment 116 of the motor vehicle 110. Each of the dump ducts 112L, 112R has the same resistance to flow as the respective distribution duct 111L, 111R to which it is connected. The flow from the distribution ducts 111L, 111R is adjusted by varying the proportion of air that flows through the cooperating dump duct 112L, 112R without affecting the flow from the other distribution duct 111R, 111L or requiring the blower speed to be altered. In one embodiment the dump ducts 112L, 112R exhaust air into a luggage compartment 117 of the motor vehicle 110.</p> |
