Abstract:
The invention relates to a ventilation system (10) with heat recovery adsorber, the ventilation system (10) for being installed in buildings, wherein the ventilation system (10) furthermore comprises at least one exterior intake/outlet opening (11) for an air stream from outside of the building and at least one interior intake/outlet opening (23) for an air stream from inside the building, at least one air fan unit (14) and at least one filter unit (12, 22), wherein the heat recovery adsorber includes a heat exchange material (16) for absorbing and releasing heat from the air streams and a sorption material (18) for at least adsorbing and desorbing at least one sorbate from the air streams, wherein the at least one sorbate is water vapor, said sorption material (18) comprising at least one adsorbent for water vapor exhibiting an s-shaped water adsorption isotherm (30) at room temperature (25° C.+/−10° C.) with a steep increase in a narrow relative humidity range, wherein a main loading lift of the adsorbent for water vapor occurs in the relative humidity range from 0.1 to 0.5 and the saturation capacity of the adsorbent for water vapor lies in the range from 0.25 to 1.2 kgwater/kgadsorbent. The invention further relates to methods and uses for combined heat recovery, cooling/heating and dehumidifying/humidifying of air streams for buildings as well as such buildings.

Abstract:
Filling device (22) for an ANG-sorption store (10) containing at least one adsorption medium (20), said filling device (22) being of tubular shape, having a mantle (36) defining a hollow interior, orifices (48) in said mantle (36), said ANG-sorption store (10) substantially mounted horizontally, wherein said orifices (48) are arranged on an upper part (62) of said mantle (36) of the filling device (22) extending in axial direction (34) through said ANG-sorption store (10).
Abstract:
A process for indicating a fill level of a sorption store (1), wherein at least one gas adsorbent medium (5) is disposed within at least one vessel (3) and wherein a total amount (n total ) of a gas (15) stored in the sorption store (1) is computed based on at least one measured temperature value and at least one measured pressure value.
Abstract:
The invention is related to a shaped body, wherein the shaped body (1, 15) is a solid body made of a porous material comprising metal-organic framework material and having a form of a polyhedron with six lateral faces (3), wherein a length (22) of one edge (5, 17) of the polyhedron differs from a length (22) of any other edge (5, 17) of the polyhedron by 10% or less and wherein all angles between two adjacent edges and adjacent lateral faces are between 85° and 95°. The invention is further related to a packing (25, 29, 33) and use of the shaped body (1, 15).
Abstract:
Method of charging a sorption store with a gas, where the sorption store comprises a closed container (10) which is at least partly filled with an adsorption medium (40) and has an inlet (21 ) and an outlet (23) which can each be closed by a shut-off element (22, 24), which comprises the steps: (a) closing of the outlet shut-off element (24) and opening of the inlet shut-off element (22), (b) introduction of gas to be stored under a predetermined pressure through the inlet (21 ), (c) rapid opening of the outlet shut-off element (24) with the inlet shut-off element (22) open so that a gas flow having a predetermined flow rate is established in the container (10), (d) reduction of the flow rate as a function of the adsorption rate of the gas adsorbed in the store and (e) complete closing of the outlet shut-off element (24).
Abstract:
A sorption store for storing gaseous substances, comprising a closed tank (10) and a feeding device (20), which comprises a passage (21) through the tank wall, through which a gas can flow into the tank (10), wherein the tank (10) has inside it at least one separating element (15, 16, 17), which is configured in such a way that the interior of the tank (10) is divided into at least one pair of channels comprising two parallel running, channel-shaped compartments (30, 31, 32, 33), the ends of which are in connection with one another in each case by way of a common space (35, 36, 37, 38), each channel-shaped compartment (30, 31, 32, 33) being filled at least partially with an adsorption medium (40), and wherein the feeding device (20) is designed in such a way that inflowing gas is diverted almost exclusively into one of the two compartments (30, 31, 32, 33) of each pair of channels.
