Abstract

A dehumidifier uses high voltage to cause moisture to condense out of an airflow in contact with a series of needles and a screen forming the cathode and anode respectively of a diode structure. Condensate is sucked into small holes in either or both of the needles and/or the screen by a vacuum. Ultra-violet light is applied to reduce the incidence of ozone.
