System för tillfredsställande av energibehovet i ett rum

摘要

For lowering the energy requirement for a room (2) ventilated by a ventilating system (11 to 17) of a building (1), windows (4) and opaque wall parts of the outside wall (3) are designed so that the heat transfer numbers (kF and kW, respectively) are smaller than 1 W/m2.K. In addition, the supply air flows into the room (2) near the floor (9) at the comfort temperature of at most 20 DEG to 22 DEG C. and an input velocity which does not exceed a maximum air velocity which is permissible for comfort conditions in an occupied zone.
