Ventilation system, ventilation system including the said ventilation system, and a method for regulating air supplied to a building during the simultaneous cleaning of identified outdoor enclosures

摘要

The present invention concerns a ventilation device (V) comprising a first inlet (1) for recycled indoor air, a second inlet (2) for outdoor air, an outlet (5) for mixed air (23);a mixing chamber (3) and a recirculation fan (41);where the first and second inputs mentioned (1) and the second inputs mentioned (2) are arranged in the said mixing chamber (3),Furthermore, the ventilation system (V) includes a second chamber (4) which is flow-linked to that mixing chamber (3) and thereafter, at least one filter (11) arranged in that first inlet (1) and at least one first filter (30) arranged between that mixing chamber (3) and that other chamber (4) and that the outlet (5) is arranged in the said second chamber (4). Furthermore, the invention concerns a ventilation system (S) for the supply of purified and conditioned air to a building;where it includes such a ventilation device (V) and a method for regulating the intake of outdoor air into a building during the simultaneous cleaning of the intake outdoor air and the purification of recycled indoor air, including the step to clean the internal air in a filter (11) before entering the mixing chamber; (3) regulating the flow of indoor air into the mixing chamber (3) by controlling a recirculation fan (41);which is designed to provide mixed air to the air ducts (23);so that the proportion of indoor air input into the mixed air (23) in the range 30-60%preferably 35-50% and even more the report around 40% is achieved.
