The invention relates to a profiled section (10) for temperature-control of a room, said section having a receiving portion (20) for a piping system positioning aid (60), a sealing surface (15), formed at least at the side of the receiving portion (20), and at least one first support (30) for a sealing panel (200), the first support (30) being formed at the side of the receiving portion (20) and pointing in the opposite direction to the sealing surface (15). The invention also relates to a building element assembly (100) comprising a profiled section (10) of this type and to an associated use.

A radiant heat transfer system for heating or cooling a room, has at least one heat exchange element in the form of a panel formed by a first plate and a second plate, the first and second plates being symmetrically profiled to form a flow channel arranged in a serpentine manner between the first and second plates for passage of a heat transfer fluid, wherein the first and second plates are pressed steel plates and are connected to each other by welding over the entire surface of the contact areas between the first and second plates, wherein the connection between the plates is made by laser welding, and wherein a surface texture obtained by laser treatment is present on the surface in contact with the heat transfer liquid of at least one of the first and second plates to increase the heat transfer.

Using thermal radiation to supply occupant comfort has long existed in the heating domain, and to a lesser scale in the cooling domain. Cooling power of radiant cooling systems is limited by the risk of condensation on the panel itself, as well as adjacent surfaces. Similarly, convective system losses to the ambient air prevent maintaining a large temperature difference from the surface and the surroundings. The disclosed approach combats these common pitfalls of radiant cooling systems in the building domain, increasing the power and therefore applicability of radiant cooling.

A system for obtaining energy consumptions, savings and cost reduction in structures adapted for human habitation which includes the utilization of a plurality of mats including phase change material encapsulated within first and second layers of plastic material having heat transfer capability disposed within the plenum area above a ceiling of a room within a building with the amount of phase change material contained within each mat being between 0.5 lbs. and 0.67 lbs. per square foot.

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.

An intermediate product for the production of a surface heat exchanger, in particular for building room air conditioning, including a support plate, on one side of which a tube system for conducting a medium is attached and on the other side of which a prefabricated adhesive tape having a manually removable outer protective layer is arranged, wherein the adhesive tape is free of any support.

A pneumatic radiation unit according to the present invention includes: a first chamber including a first air discharger configured to discharge air-conditioning air to a second chamber; and the second chamber including a second air discharger configured to discharge the air-conditioning air to a space to be air conditioned, the second chamber being configured to take in the air-conditioning air from the first chamber and discharge the air-conditioning air and radiate heat to the space to be air conditioned. A second aperture ratio of the second air discharger is set to be greater than a first aperture ratio of the first air discharger, or a cross-sectional area of a flow passage of the air-conditioning air in the first chamber is gradually reduced from an upwind side to a downwind side of the flow passage of the air-conditioning air.

A hydronic panel and system for heating and/or cooling a room is disclosed. The hydronic panel includes a plurality of contiguous channels. A first chamber is located at a first end, preferably the upper end, of the panel and includes an inlet and communicates with a first subset of the channels. A second chamber is located at an opposite end of the panel and communicates with the first subset and also with a second subset of the channels. A third chamber is located at the first end of the panel, the third chamber communicates with the second subset of the channels and includes an outlet. In this configuration, heated or cooled water flows from the inlet into the first chamber, through the first subset of the channels, to the second chamber, through the second subset of the channels, into the third chamber and out the outlet. Consequently, the heated or cooled water can heat or cool the space. In addition to at least one hydronic panel, the system includes a source of heated and/or cooled water under sufficient pressure to cause the water to flow through the panel. The system also includes a controller to control one or both of the temperature of the water and the flow rate of the water through the panel.

A building system comprising of a plurality of panels wherein the building system is configured to be either superposed an existing structure or a ground surface. The plurality of panels of the building system are shaped so as to be mateable when place adjacent to each other. The panels include a bottom and walls that form an interior volume. The bottom and walls of the panels are manufactured from a thermally conductive material such as but not limited to metal. The interior volume of the panels are filled with a lightweight structural material such as but not limited to polyurethane foam or autoclaved concrete. A first temperature source is disposed within the panels and is configured to have a fluid pass therethrough. A second temperature source is present and is a heating element. The panels are operable to utilize either temperature sources.
