Patent ID: 10343489

Abstract:
An evaporative HVAC apparatus is disclosed for use in a vehicle air conditioning system. In at least one embodiment, the apparatus provides a housing positioned substantially in front of a vehicle evaporator and having an inner surface that defines an air passage extending therethrough. At least one thermal core is positioned within the housing. The at least one thermal core comprises at least one absorbent wicking layer sandwiched between a pair of substantially planar thermal layers. At least one fluid line is in fluid communication with the at least one wicking layer. Thus, as air from a vehicle blower moves through the evaporator and subsequently through the housing, a fluid is selectively delivered to the at least one wicking layer through the at least one fluid line which, in turn, permeates each of the thermal layers and evaporates into the air located immediately adjacent an exposed first surface of each of the thermal layers, thereby affecting the temperature of said air before it enters a cabin area of the vehicle.
