The invention relates to a surface heat exchanger (10), in particular for air conditioning rooms (16), comprising an in particular perforated support plate (11), preferably made of metal, on one side (12) of which a tube system (13) for conducting a medium is attached, in particular directly, wherein the surface heat exchanger (10) comprises an outer, non-metal decorative layer (16), which is arranged on, in particular adhered to, the other side (15) of the support plate (11), in particular directly.

A control system is provided for controlling heating and/or cooling with a conditioning load such as fan coils and chilled beams. Based on user input and ambient conditions, the control system determines a desired temperature for the liquid entering the load and combines fresh supply liquid (e.g., from a chiller or boiler) with a portion of the liquid that has passed through the load, to achieve the target load input temperature for the liquid. A recirculation pump may be used to return a portion of the liquid exiting the load for mixing with the fresh supply liquid and a control valve may be used to adjust the ratio of fresh supply liquid and recirculated liquid to achieve the targeted temperature. The control systems can be compatible with a variety of liquid supply systems such as two- and four-pipe systems.

There is provided an electric suspended radiant disk heater apparatus comprising: a central and vertical ceiling mount pole for hanging from a ceiling at an upper end thereof in use; a radiant heater disk element fastened at a lower end thereof, the radiant heater disk element being substantially co-axial with the ceiling mount pole, being substantially perpendicular to the ceiling mount pole and extending radially from the lower end of the pole; and an electric heater element thermally coupled to the radiant heater disk element to heat the radiant heater disk to radiate heat from a radiant heat emitting undersurface thereof.

The invention relates to a building panel intended for creating heating and/or cooling walls of buildings, comprising: a base element defined by an upper face, a lower face and several lateral faces, circulation means (12) for the circulation of a heat-transfer or cooling fluid, which are arranged on the inside of said base element, a substantially flat conducting element, fixed to the upper face of the base element so as to cover it entirely or almost entirely, said conducting element having good thermal conductivity, mechanical connection means secured to said base element, said mechanical connection means being able to allow removable attachment of said building panel to an identical or similar building panel arranged adjacent to the latter, fluidic-connection means designed to allow the heat-transfer or cooling fluid to circulate between said building panel and an identical or similar building panel attached thereto, leak detection means able to detect a leak of heat-transfer or cooling fluid at the lower or upper face of the base element.

The thermally activated building panel (1) includes a metal plate (2) having a room-facing surface (3) and a building-facing surface (4). A heat-exchanger tube (5) for conveying a cooling or heating medium is in conductive thermal contact with the building-facing surface (4) of the metal plate (2). A textile (9) is arranged on the room-facing surface (3) of the metal plate (2) and has a first surface (10) generally contacting the metal plate (2) and a second surface (11) generally visible from said room. The textile (9) is tensioned between opposed edges (12) of the metal plate (2). The first surface (10) of the textile (9) is metallized by deposition of metal particles on the textile (9).

A thermally-conductive material includes: a textile fabric; and a graphite-containing, thermally-conductive coating, in which graphite is present in a proportion of 5 wt % to 50 wt % relative to a total weight of the thermally-conductive material. The thermally-conductive material has a flow resistance of 60 Pa*s/m to 400 Pa*s/m. In an embodiment, a proportion of graphite in relation to the thermally-conductive coating is more than 50 wt %.

A multifunctional ceiling structure, in particular for living spaces and workspaces, and includes multiple heat-conducting profiles that are directly or indirectly fastened to a building ceiling, and a downwardly directed mounting surface, with a line receiving region formed in the mounting surface. Furthermore, a heating medium line is provided that runs in the line receiving region of the heat-conducting profiles and conducts a heat-transporting medium. A ceiling panel is fastened to the mounting surface of the heat-conducting profiles and is in heat-conducting contact with the heating medium line. An absorber strip made up of sound absorber elements extends along an upper abutting edge that runs between a building wall and the plane of the ceiling panel. The sound absorber elements have a width of 200-400 mm, a thickness of 25-65 mm, and a length-specific flow resistance in the range of 8-10 kPa*s/m.sup.4.

A stationary infrared radiator which is to be operated in a decentralized manner for heating buildings, including a reflector and at least two different components which emit IR radiation for heating, the reflector having a longitudinal axis (L) and a transverse axis (Q), which runs at right angles to the longitudinal axis (L) and parallel to the reflector, and a reflector surface. The first component is designed as a bright radiator or as a dark radiator and has a connection for supplying fuel gas. The second component is designed as an electrical resistance heater having at least one heating element. The aim is to control the temperature more precisely and simultaneously to produce the infrared radiator more simply. The first component and the second component are respectively disposed offset from one another in a direction of the transverse axis (Q) and in a direction at right angles to both axes (L, Q) in front of the reflector surface.
