20140290785 | VENTILATION DUCT - A duct includes a number of wall sections which are at least partly produced from fibre material and a binder agent. Together, the wall sections define a closed, elongate flow space. The wall sections which meet one another are united by the intermediary of at least one longitudinal fold or joint line. In the fibre material and the binder agent of the duct, there are disposed longitudinal rigidifying elements. On the outside of the duct, there are longitudinal bead-liked projections which include the fibre material and the binder agent. | 10-02-2014 |
20130020798 | CONNECTING PIECE AND A METHOD AND TOOL FOR ITS MANUFACTURE - A connecting piece for a duct such as a ventilation duct is provided and includes an inner flow space in communication with the interior of the duct, the connecting piece having at least one joining portion on which an end region of the duct is slidable and fixable. The connecting piece includes a compressed fiber material and a binder. The connecting piece displays a substantially configurationally stable portion in association with the joining portion, and the connecting piece displays, at least interiorly, a layer which is impervious to a fluid, in particular a gas, this layer being adjacent the inner flow space of the connecting piece. | 01-24-2013 |
20120255705 | METHOD AND AN APPARATUS IN A VENTILATION SYSTEM - A method for recovering heat and humidity in a ventilation system includes cooling warm and humid exhaust air at a condensation surface in a heat exchanger and collecting the condensate as formed, heating dry and cold supply air at the opposite side of the condensation surface and atomizing the condensate and supplying the atomized condensate to the supply air at the supply air inlet of the heat exchanger. The atomizing is generated b a piezoelectric atomizer. A device for recovering heat and humidity in a heat exchanger in a ventilation system includes a condensation surface at the exhaust air side of the heat exchanger and a collection device for condensate. At the inlet of the supply air side of the heat exchanger there is provided a piezoelectric atomizer that is fed with the condensate for supplying atomized condensate to the inlet. | 10-11-2012 |
