Abstract:
1. An air conditioning system for a motor vehicle having a passenger compartment, the air conditioning system comprising: an air conditioning unit having a single blower for causing air to flow; a first air flow conduit through which a variable first air flow is flowable from the single blower, and a second air flow conduit through which a variable second air flow is flowable from the single blower, the first air flow conduit and the second air flow conduit being fluidly in parallel; a first distribution conduit through which a first portion of the first air flow is flowable to the passenger compartment, and a first dump conduit through which a second portion of the first air flow is flowable to a trunk space outside of the passenger compartment; a second distribution conduit through which a first portion of the second air flow is flowable to the passenger compartment, and a second dump conduit through which a second portion of the second air flow is flowable to the trunk space; a first distribution valve connecting the first air flow conduit to the first distribution conduit and the first dump conduit, the first distribution valve being configured to inversely vary the first portion of the first air flow flowing through the first distribution conduit, and the second portion of the first air flow flowing through the first dump conduit; and a second distribution valve connecting the second air flow conduit to the second distribution conduit and the second dump conduit, the second distribution valve being configured to inversely vary the first portion of the second air flow flowing through the second distribution conduit, and the second portion of the second air flow flowing through the second dump conduit; wherein the first dump conduit has a flow resistance the same as a flow resistance of the first distribution conduit, and the second dump conduit has a flow resistance the same as a flow resistance of the second distribution conduit.
