In the preferred mode, an apparatus is disclosed to carry out a vehicular humidification process which includes the steps of bubbling pressurized hot air (17)(e.g., trim air) upwardly through a plurality of tubes (34) submerged in a body of water, evaporatively combining the inlet air (17) and water (8) in a venturi (34b) which has its divergent walls at a predetermined angle (8) and its exit above the water level (16), mechanically separating the excess droplets in a baffle (60), in-line filtering (26) the humid air (17b) and discharging the filtered air into a duct leading to a compartment (22) to be conditioned (e.g., the flight deck of an aircraft). Further steps include maintaining a uniform level of dissolved minerals in the water sump including swirling (145) the water, mixing outlet air with other air (12a) including bypassed (20) dry inlet air, recirculating (53) humid outlet air to the inlet, draining (9) the water body (8) when overfilled, periodically draining (14 ) the water body to eliminate dissolved minerals and controlling (37) the water level (38, 39). All variable parameters are sensed (15, 23, 24, 28, 29, 30, 88, 98) and automatically controlled (11). There are no moving parts except a fan (51, 90), when required by a mode, and the control valves (13, 14, 18, 19, 27, 80, 86, 87). Numerous alternative embodiments are presented.
