Condensate drain pan for air-conditioning unit

摘要

A drain pan is provided for removing copper ions from condensate water produced by a heating, ventilation and air conditioning unit. The pan defines a volume having two closed ends and an open top so that water can evaporate from the pan. As least one copper removing agent is placed in the pan, and a baffle 24 is provided between the ends of the pan for routing water entering the pan at one end through the removing agent en route to an outlet 22 at the other end. The removing agent may include mossy zinc and/or activated charcoal. The arrangement prevents the copper ions corroding roof panels with roof-mounted hvac units.
