  • Compact automotive air conditioning module
    Patent number: 6045444
    Abstract: A compact HVAC module housing (30) incorporates a novel temperature valve belt (74) and support frame therefore (60) that fit between an evaporator (56) and heater (58). This allows the entire housing (30) to be very compact, and to be more easily integrated into a vehicle body structural cross beam (32). The temperature valve and its location, as well as a reversed air stream through the heater (58), together allow the mixing area for the cold and not air streams to be well within a minimal space envelope of the housing (30), rather than outside of it.
