Compact automotive air conditioning module
General Motors Corporation
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.

An automotive heating, ventilation and air conditioning housing (30) that is generally divided into upper (B) and lower (A) upstream quadrants and upper (D) and lower (C) downstream quadrants as defined by the space envelope occupied by a larger, upstream evaporator (56) and a smaller, downstream heater (58) contained within said housing (30), with the evaporator (56) located across both upstream quadrants (A, B) and the heater (58) located substantially within just the lower downstream…
