Abstract

The invention relates to a ventilation-heating unit, comprising one or more heating elements which are supplied with thermal energy from an external heat source. The unit has an outside-air fan, an extract-air fan and a supply-air fan, by means of which supply air is blown through the supply-air nozzles via the heating elements of the unit. The unit is integrated to form a compact aggregate unit including the said fans and the air ducts present between these. In the unit, the pressure side of the outside-air fan is connected to the suction side of the supply-air fan, to which, in addition, the recirculating-air duct belonging to the unit is linked. The flow resistances of the individual inner air ducts of the unit are dimensioned and/or set in such a way that, on the pressure side of the outside-air fan and on the suction side of the supply-air fan, which are interconnected, there prevails a negative pressure which can be set by the unit and is substantially constant at various operating points. The flow direction of the recirculating air (return air) remains directed towards the unit in spite of the different quantities of air varying from one another.
