Claim:
1. An evaporative HVAC apparatus comprising: an at least one housing having an inner surface that defines an air passage extending through the housing; an absorbent wicking layer formed immediately adjacent and directly attached to at least a portion of the inner surface of the housing; a thermal layer formed immediately adjacent and directly attached to an inner surface of the wicking layer, thereby sandwiching the wicking layer between the thermal layer and the inner surface of the housing, an exposed inner surface of the thermal layer defining a substantially tubular-shaped air passage extending through the thermal layer in fluid communication with the air passage of the housing; and the housing providing an at least one fluid inlet aperture through which a fluid line extends a distance into the housing so as to be in fluid communication with the wicking layer; whereby, a fluid is selectively delivered to the wicking layer through the fluid line which, in turn, permeates the thermal layer and evaporates into the air located immediately adjacent the exposed inner surface of the thermal layer, thereby affecting the temperature of the air moving through the air passage of the thermal layer.
