Patent number: 9074790Abstract: The invention relates to a plenum box (1a, 1 b) configured for use in a ventilation system (2) with flowing air in order to be able to quickly regulate flows between the ventilation system (2) and a room. The plenum box (1) comprises a pressure distribution pipe (4) which is disposed in an inlet (3) to the plenum box (1) and which itself comprises a regulating damper (5), and an outlet (6a, 6b). The inlet (3) is configured to have an air flow (7) passing through it. The pressure distribution pipe (4) extends inside the plenum box (1a, 1b) from the inlet (3), and the surface of the pressure distribution pipe (4) has perforations (8) which allow the air flow (7) to pass through them between the inside (9) and outside (10) of the pressure distribution pipe (4).Type: GrantFiled: July 8, 2009Date of Patent: July 7, 2015Assignee: Lindab ABInventors: Goran Hultmark, Robert Salomonsson, Martin Jespersen, Anders Vorre

Publication number: 20080086884Abstract: A method for manufacturing a heat-exchanger and in particular a heat-exchanger suitable for energy transfer between a plate and a fluid circuit. A sheet metal plate and a predetermined length of continuous metal tubing are prepared. The length of metal tubing is successively applied to the sheet metal plate. The successive application includes bringing the metal tubing into close contact with the sheet metal plate and affixing the metal tubing to the sheet metal plate.Type: ApplicationFiled: November 25, 2005Publication date: April 17, 2008Inventor: Goran Hultmark

Patent number: 6520247Abstract: An air-conditioning device especially for ceiling placement with low build-in height and comprising at least one preferably vertically oriented heat exchanger, with substantially horizontal percolation of the room air and at least one ventilation channel for fresh air provided substantially parallel to and within a small distance from the heat exchanger, at its outlet side, a downwards open air chamber provided between the ventilation channel and the heat exchanger, and air nozzles provided in the channel side wall of the ventilation channel facing the air chamber, which are directed towards the outlet of the air chamber. The ventilation channel is provided with a preferably convex channel wall which diametrically extends substantially from the upper corner of the ventilation channel to the lower corner of the ventilation channel. The heat exchanger and the ventilation channel are arranged with a downwards, diverging open air space.Type: GrantFiled: May 1, 2001Date of Patent: February 18, 2003Assignee: Teknoterm Climate ABInventor: Göran Hultmark

Patent number: 6171458Abstract: A spectral selective absorbing surface on solar collector elements has a very high solar absorbing ability, in the range of 96% to 97% and a low thermal emittance, in the order of 10%, and can be produced with high capacity in industrial scale. A reactive gas in an amount of 1 to 50 cm 3/min kW, preferably 10 cm 3/min kW, distributed in the coating zone provides that the metal layer deposed onto the receiving material partly oxidizes during the deposition, whereby a layer is obtained that comprises a grain mixture of metallic material and metal oxide, whereby 40% to 80%, preferably about 50%, of metallic material is embedded into the metal oxide closest to the receiving material. The metallic material is successively decreased to about zero at the surface of the layer by increasing the addition of oxygen at the end of the coating zone.Type: GrantFiled: March 10, 1999Date of Patent: January 9, 2001Assignee: Sunstrip ABInventor: Göran Hultmark

Patent number: 4726559Abstract: Means of attachment of the kind that comprises a fittings (11) which is easily mountable and dismountable to an object (26) and displaceable sideways with respect to this. The purpose is to provide a means of attachment which is easily mountable and dismountable, which can be fixed along the edge sides of the object without using tool, which is simple and cheap in manufacturing and which offers a strong and effective attachment. These problems have been solved by the fact that the object (26) is provided with grooves (27,28) or the like arranged substantially parallel, spaced apart and opposite each other, that the fittings (11) consists of two plate-shaped parts (12,13) partially overlapping each other, the brought-together position of which corresponds to the distance between the grooves (27,28), and that at least one part (12) is designed with means (17) arranged to fix the free end section (18) of the other part (13) against displacement across the plane of the parts.Type: GrantFiled: September 12, 1986Date of Patent: February 23, 1988Assignee: Scandinavian Solar ABInventor: Goran Hultmark
