Method and device for dehumidification

摘要

The method involves producing circulating air using a ventilator (10). An exhaust air is produced temporally based on a water vapor partial pressure difference between inside and outside and/or based on relative interior air humidity. The exhaust air is produced based on an external dynamic pressure in an exhaust air area. Heating, which is effective with respect to an upper surface, is carried out, where the object and/or the structure is heated. An independent claim is also included for an arrangement for dehumidifying object or structure in an area.
