Definitions

  • the invention relates to a central heating system in which the heat transfer medium is a flowing liquid, preferably water, and in which the heat generating elements consist of elongated extruded pro- file members made from a material of high thermal conductivity, e.g. aluminium, and provided with a longitudinal duct for the heat transfer medium.

  • radiators are used as the heat generating elements interconnected and communicating with the heat producing boiler by means of insulated or uninsulated tubes and fittings.
  • the disclosure of the published German patent specification DE-OS No. 3140048 relates to the use of profile members of extruded aluminium as the heat generating elements, each of which having an open duct accommodating a copper tube for the transfer of hot water.
  • the profile aluminium members are assembled as heating panels at the transition between a wall and floor and they are connected with usual tubes and fittings.
  • each profile member is provided with at least one further longitudinal duct, of which at least one is lined with a heat insulating material.

  • the profile aluminium members may be mounted as heating panels on one or more of the walls in a room, either at the foot along the floor or just beneath the ceiling. Valves for total or partial switching the flowing hot medium between lined and unlined ducts may be inserted between adjacent sections of profile members, thereby obtaining a very simple way of regulating the heat generated by the profile members.
  • the invention also relates to a method of manufacturing a profile member for use in a central heating system according to the invention, said method being characterized in that an elongated profile member with at least two ducts extending throughout the member is extruded from a material of high thermal conductivity, e.g. aluminium, and in that at least one of the ducts is lined with a heat insulating material.
  • the lining may be obtained by pressing a plastics tube, e.g. PVC-tube, into one or more of said ducts.

Abstract

Dans le système de chauffage central décrit, les éléments générateurs de chaleur et de préférence également les éléments de transfert du milieu chauffant se composent d'éléments profilés extrudés et allongés (1) fabriqués dans un matériau à haute conductivité thermique telle que l'aluminium, lesdits éléments profilés étant pourvus d'au moins deux conduits (2, 3), dont au moins un (3) est garni d'un matériau thermo-isolant (4). Lorsque l'écoulement du milieu chauffant est dirigé à travers le conduit non garni (2), l'élément profilé fonctionne comme un radiateur chaud, et lorsque l'écoulement du milieu chauffant est dirigé à travers le conduit garni (3), ledit élément fonctionne comme un radiateur froid ou comme un tube isolé thermiquement. Des vannes (14) sont disposées entre des éléments profilés adjacents pour permettre le passage total ou partiel de l'écoulement du milieu chauffant entre un conduit garni et un conduit non garni.
