Humidifier with surface evaporation

摘要

The humidifier has an evaporation body arrangement. The evaporation body arrangement (2) is divided into an air upstream region and an air downstream region. Each region is impacted separately with water. One region may be sprayed with fresh water and the other with recycled water. A water collection device may be arranged under one of the regions and the collected water is then used on the other region. Independent claims also cover a method of operating the apparatus.
