Active condensation occurs on mechanically cooled surfaces (surfaces cooler than the air temperature)—where a generated power source such as electricity is needed to cool the surface on which the atmospheric water (moisture in the air) condenses. That condensation can be harvested by directing the condensate drain to where the water can be utilized as a resource.
The first active condensate recovery systems from air conditioners and other refrigeration appliances in San Antonio have worked so well that San Antonio became the first city to require new commercial buildings design drain lines so that condensate can be captured and reused on site (OSA 34-274.1 Condensate Collection).
