Ventilation device with heating, as well as a building containing such a ventilation device

摘要

A building (23) comprises a façade (2) and a passive ventilation system for passively supplying outside air to the building on account of a pressure difference between the exterior (17) and the interior (18) of the building, which ventilation system comprises a passage means (1, 26) which is provided in the façade and extends between said exterior and interior of the building and is configured such that it provides an air flow on account of said pressure difference. In order to prevent an unpleasant draught, a heating means (20, 20') is provided in the form of a sheet or plate made of electrically conductive material which heats the incoming air. A ventilation device (1) for use in such a building carries such a heating device (20).
