<p>Ventilation and heating arrangements for building interiors, in particular industrially used rooms e.g. workshop halls, require efficient ventilation and heating, the heating costs also depending upon the extent of the ventilation. To reduce energy costs, it is envisaged that a ventilation and heating arrangement, with at least one ventilation duct which is connected on the inlet side to controllable air inlets for outside air and for room air and opens into the interior via a blowing-out opening and which is assigned at least one heating device, at least one fan as well as a control arrangement with a switch clock or similar timer for a temporally changing day and night operation, is designed in such a manner that the control arrangement, in each case preceding predetermined times, defines a heating period, in which, when the fan and heating device are switched on, the air inlets for outside air and room air are set in the opposite direction to circulating-air operation. Preferably, the control device is then at the predetermined times switched over to a day-operation control with heating being controlled according to the temperature of the room air.</p> |
