Abstract: A rotary heat exchanger through which a first fluid flow—an outside air or inlet air flow, for example—and a second fluid flow—an exit air or outgoing air flow, for example—can flow in a counterflow configuration, has a rotatably mounted rotor (5) that has a first flow sector for the first fluid flow and a second flow sector for the second fluid flow through which the rotor (5) passes during a rotation, a frame in which the rotor (5) is rotatably supported, and a sealing assembly (9) by means of which an inflow side of the first fluid flow and an outflow side of the second fluid flow can be separated from the outflow side of the first fluid flow and from an inflow side of the second fluid flow, respectively.

Abstract: The invention relates to a device for conditioning an air flow(2) comprising a humidifying apparatus (5) having humidifying elements(6), which are arranged in the air flow (2) to be humidified in the humidifying apparatus(5), can be loaded with pressurized water, and are made of a fluid-permeable, porous, preferably hydrophilic material. In order to increase the efficiency of the humidification of the air flow(2) in the humidifying apparatus (5), the humidifying elements(6) of the humidifying apparatus(5) loaded with pressurized water are designed with regard to the cross-section thereof in such a way that the peripheral surface or outer surface of the humidifying elements exposed to the air flow(2) to be humidified can be uniformly contacted by the air flow (2) to be humidified over the entire circumference of the humidifying elements.

Abstract: The invention relates to a rotating heat exchanger (1) with a rotatably mounted rotor (3), comprising a first flow sector (4), for external (5) and supply air (6) and a second flow sector (7), for exhaust (8) and venting air (9), through which the above runs on rotating and a housing (2), enclosing the rotor (3) around the circumference thereof, whereby to improve the sealing of the rotor (3), the housing (2) around the circumference thereof is filled with housing or sealing air, whereby the pressure of the housing or sealing air is higher than the pressure of the airflows (5, 6; 8, 9) flowing through the rotor (3).

Abstract: The invention relates to a humidity- and/or heat-exchange device, for example a plate heat exchanger a sorption rotor, an adsorption dehumidifying rotor or the similar, provided with humidity- and/or heat exchange surfaces which make it possible to introduce humidity and/or heat into a fluid flow and/or to remove them therefrom and/or to exchange said humidity and/or heat between fluid flows. The inventive device is also provided with a coating, which makes it possible to cover said humidity and heat exchange surfaces and consists of a zeolithe material and a bonding agent. In order to improve the performance of the humidity- and/or heat-exchange device, the zeolithe material is embodied in the form of a synthetic nano-zeolithe consisting of particles whose size is <1000 nm.

Abstract: A sorption rotor has end faces and is rotatably journaled to travel during a revolution through an inflow sector and an outflow sector. The rotor is made of a matrix material having a honeycomb structure with axially throughgoing flow passages. The matrix material is constituted of cellulose paper modified by a ceramic material infiltrated by a sol-gel system or a gel-forming low-viscosity liquid into the matrix.
