Abstract
An automotive air conditioning system including a folded duct for conveying conditioned air to a passenger compartment, a blower for forcing air through the duct and a partition wall for separating the passenger and engine compartments. The blower is positioned adjacent to one end of the duct which is in fluid communication with an opening formed in the partition wall. The one end of the duct is associated with a shell which covers at least a portion of the blower. The duct has a heater element and an evaporator disposed therein, wherein the evaporator is positioned at a bent portion of the duct. The shell, a portion of the duct and wall adjacent one side of the evaporator form a chamber. An air intake mechanism is associated with the chamber for alternately introducing air, either external to or from the passenger compartment, into the chamber. The air intake mechanism includes a control mechanism which forms part of the chamber and controls the source of air intake.
