ABSTRACT:
The invention relates to a HVAC drainage system. There is a need for an HVAC drainage system which operates well in a vehicle which moves over rough terrain. An HVAC unit is mounted at a central portion of an inner roof panel over an air inlet opening. A collection recess is formed by the panel and surrounds the air inlet opening. Concentric walls formed by the inner roof panel in the collection recess surrounding the HVAC unit. Each wall has one or more gaps formed therein. The gaps in adjacent walls are mis-aligned with respect to each other so that fluid is prevented from flowing in a straight line through gaps in adjacent walls. Drainage ports are formed in the inner roof panel. Drainage grooves formed in the inner roof panel communicate the collection recess with corresponding drainage ports.
