Eliminating/inhibiting moisture deposits on internal building walls subject to condensation involves forced ventilation if temperature at wall surface below computed dew point temperature

摘要

The method involves determining the dew point temperature on the basis of the wall surface temperature, room air humidity and room air temperature using a microprocessor (4) and if the temperature at a wall surface is below the dew point temperature activating forced ventilation of the condensation-endangered internal wall surface. An independent claim is also included for an arrangement for implementing the inventive method.
