Ventilator for building with positive air circulation in rooms - has outgoing air passing between double glazed window panes

摘要

Ventilation appts. for building with positive air circulation in rooms operates with the outgoing air passing through the gap (13) between outer and inner panes (14, 15) of the windows of the rooms. The inner pane consists of a double glazing unit. In the outgoing air system upstream of the window is a heat exchanger (6) through which the incoming air is conducted before being introduced into the rooms. The heat exchanger pref. extracts both heat and moisture e.g. by condensation and/or absorption from the warmer air becoming cooled in it, and the extracted moisture is passed to the colder air becoming heated in it. Pref. there are several windows connected in parallel with each other in the outgoing air system.
