Abstract: A vacuum sorption device includes a volume area, in which a sorbent which periodically sorbs and desorbs a refrigerant is situated and which is formed at least partially enclosed by a condenser. The condenser is bounded by an outer wall of the volume area and a further enclosure wall. Alternately at least one of the outer wall and the enclosure wall is provided with embossments oriented toward the respective other wall to fix a flow gap width in the condenser.

Abstract: The invention relates to a boiler comprising a combustion chamber which is surrounded at least in part by a combustion gas flue that is embodied as a primary heat exchanger. The combustion gas flue is enclosed at least in part by a water-conducting housing while a water-conducting secondary heat exchanger that is hydraulically connected to the housing is mounted downstream of the combustion gas flue. According to the invention, the combustion chamber is surrounded at least in part by the secondary heat exchanger.

Abstract: A vacuum sorption apparatus includes a first volume region (1) in which a sorber (2) which periodically sorbs or desorbs a refrigerant and a condenser (3) are located, and a second volume region (4) located below the first, in which an evaporator (5) is located, wherein a separating body (6) is located above the evaporator (5) to minimize a free surface area of the liquid refrigerant. The separating body (6) is configured to be vertically movable to compensate for different filling level heights of the refrigerant.

Abstract: The invention relates to an adsorber element and to a method for the production thereof, comprising a carrier material (1) on which adsorbent particles (3) are arranged as the adsorber layer using a binding agent (2). According to the invention, the adsorber layer comprises inorganic fibers (4) and the binding agent (2) is designed as a colloid.

Abstract: The invention relates to a device having a network server computer (277) and a controller (276) for controlling a domestic technology device, wherein the network server computer (277) comprises a memory unit (279) for storing at least one website using at least one input means (306-316) for actuating the controller (276), and at least one communication interface (281, 283, 285) for establishing a network connection, via which the website can be retrieved. In order to enable a transparent and user-friendly control and monitoring of a domestic technology device, the invention provides that the network server computer (277) is integrated at least partially into the controller (276).

Abstract: The invention relates to a heating device comprising at least one heat exchanger that spirals helically around a spiral axis, is traversed by a heating medium and is configured as a flat tube comprising ends of the spiral on the feed flow and return flow sides and heating medium connections, said heat exchanger defining a corresponding spiral-shaped flow opening. A cap-type sealing housing is attached in a fluid-tight manner to at least one end of the spiral and the heating medium connection is situated on the housing. At least one end of the spiral is obliquely truncated in relation to the spiral axis and the end of the sealing housing on the spiral side has a corresponding inverse oblique configuration. Preferably, the heating medium connection on the cap-type sealing housing runs in the direction of the spiral axis.

Abstract: The invention relates to a fuel-cell installation comprising: a reformer stage, which can be heated by a gas burner in order to carry out the water-vapour reformation of hydrocarbon and water-vapour into hydrogen and additional reformer products; at least one conversion stage, which is connected downstream of the reformer stage for the chemical preparation of the reformer products; and at least one fuel-cell stack, which is connected downstream of the conversion stage and comprises a plurality of anodes and cathodes with corresponding supply and discharge connections for converting the hydrogen into water to generate an electric current and heat. The fuel-cell stack is configured as a high-temperature fuel-cell stack with an operating temperature between about 100° C. and about 200° C.

Abstract: The invention provides a combined heat and power plant with an integrated gas production system. The combined heat and power plant contains a steam reformer heated with a gas burner which converts a mixture of hydrocarbons and water vapour into a reformate gas stream containing hydrogen and carbon monoxide. The plant further contains a reactor system with several stages for removing carbon monoxide from the reformate gas stream. The plant also contains a heat exchanger for removing heat energy from the reformate gas stream and a fuel cell unit for producing electrical energy by catalytic reaction of the hydrogen contained in the reformate gas with oxygen in the fuel cell, wherein the reformate gas stream is supplied to the anode in the fuel cell unit and the anode waste gas is taken to the gas burner of the steam reformer as fuel, via a gas pipe.
