ABSTRACT:
An air conditioning and heating system is disclosed having a manually operated air temperature door that is movable in both an air conditioning mode and a heating mode to regulate the amount of air passing through a heat exchanger to thereby control the temperature of the air delivered by the system. Adapted thereto is an air temperature control arrangement comprising an air baffle that is movable with and adjustable relative to the air temperature control door so as to adjust the amount of air passing through the heat exchanger in the various regulating air temperature door positions. A dual cam track operated air baffle control adjusts the air baffle relative to the air temperature door with movement of the latter and selectively according to one of two predetermined and different cam tracks having linearity patterns determined by the respective air conditioning mode and heating mode heat transfer requirements so as to provide substantial linearity between the temperature of the air delivered by the system and the air temperature control door position in both the air conditioning and heating modes.
