Abstract
An evaporator including a housing defining an air inlet, an air outlet, and a reservoir for a liquid supply; a blower for producing air flow in a path between the inlet and the outlet; a vessel retained by the housing above the reservoir and adapted to retain a liquid volume; a wick means retained by the vessel and comprising a source portion submerged in the liquid volume and an evaporative portion disposed in the air flow path, the wick means adapted to provide by capillary action liquid flow from the source portion to the evaporative portion; and a pump means for pumping liquid from the reservoir to the vessel so as to maintain the liquid volume therein. The output capacity of the evaporator is increased by pumping liquid from a reservoir upwardly to a supply vessel.
