  • Publication number: 20110138824
    Abstract: The invention relates to a method for carrying out a heat transfer between alternately working adsorbers (Ad1, Ad2) in an adsorption refrigeration installation comprising an external cooling circuit (Kw) and an external heating circuit (Hw). The method is characterized by a closed heat transfer circuit, connected between the first and the second adsorber, comprising a heat transfer medium (Wm) circulating therein, a heat transfer with the external cooling circuit (Kw) being carried out in the heat transfer circuit via a first heat contact and a heat transfer with the external heating circuit (Hw) being carried out via a second heat contact.

  • Publication number: 20110027506
    Abstract: The invention relates to a functional composite material consisting of a support (1) and a functional surface material (2). The composite material is characterised in that the support has a structured boundary layer (3) with a lower boundary (4), an upper boundary (5) a cross-linking depth (d) between the lower and upper boundaries and a substance boundary (6) that alternates between the upper and lower boundaries on the surface facing the functional surface material. The substance boundary (6) is designed in particular as a continuous sequence of surface moulded sections (7) of the support with spaces (8) therebetween, each moulded section having a height (h) that equals the cross-linking depth and at least one moulded section and at least one space (8) lie within a horizontal width (b) corresponding to a multiple of the cross-linking depth.

  • Publication number: 20110005246
    Abstract: The invention relates to a method for controlling the power of a sorption refrigeration system, comprising an adsorber unit, a condenser (C), and an evaporator (E) through which a cooling carrier fluid (KT) flows, with alternating application of the adsorber unit by a valve unit (HV_IN, HV_OUT) operated via a controller, having a circuit process of at least one sorption phase and at least one heat recovery phase, wherein a measurement of a current cooling carrier outlet temperature (Takt) is carried out in the return of the evaporator, a calculation of an averaged cooling carrier outlet temperature (Tgem) is carried out during the first and second sorption phases with a comparison to the current cooling carrier outlet temperature (Takt), and a control signal is trigger upon completion of the sorption phase as a function of the difference between the averaged cooling carrier outlet temperature (Tgem) and the current cooling carrier outlet temperature (Tgem). The invention provides a corresponding device.

  • Publication number: 20100293989
    Abstract: The invention relates to a compact sorption cooling unit, comprising at least one adsorber/desorber unit (1) having a heat exchanger and sorption material, at least one condenser heat exchanger (5), and at least one evaporator heat exchanger (6), wherein these building blocks are located in a common, vacuum-tight metal outer housing, and having connection and coupling elements and pipe ducts for the hydraulic interconnection and operation of the unit. The invention provides a sandwich structure, wherein the at least one adsorber/desorber unit (1) is located in an inner or partial inner housing. The condenser heat exchanger (5) and the evaporator heat exchanger (6) are disposed at a distance from each other, and the inner housing having the adsorber/desorber unit (1) is provided in the intermediate space thereof. The separating surfaces (2) of the inner housing directed toward the condenser heat exchanger (5) and toward the evaporator heat exchanger (6) receive steam valves (8, 9).

  • Publication number: 20090090491
    Abstract: The invention relates to a method for production of a zeolite layer on a substrate containing metal, comprising the following method steps: production of an aqueous suspension, comprising several components, one component comprises at least one cross-linking element from the third, fourth or fifth main group of the periodic table, the substrate containing metal comprises at least one of the cross-linking elements, introduction of the substrate containing metal to the aqueous suspension, heating the aqueous suspension and the substrate containing the metal present therein for the in-situ crystallisation of a zeolite layer on the substrate containing metal, whereby the cross-linking elements in the substrate containing metal are extracted and included in the zeolite layer, a cross-linking element present in the suspension for formation of the zeolite layer is present at a concentration so low that a crystallisation in the suspension is largely or completely avoided and said element is principally provided by th

  • Publication number: 20080066473
    Abstract: A system and method for air-conditioning motor vehicles and, in particular, to an air-conditioning systems for motor vehicles having adsorption heat pumps. The apparatus includes a two adsorber chambers, each connected to a condenser and an evaporator via different connection elements; a vacuum shell for enclosing the adsorber chambers, the condenser, and the evaporator, wherein the vacuum shell is not self-supporting; and one or more adsorbers housed in the adsorber chambers, wherein the adsorbers are comprised of a carrier material coated by a sorbent. The method includes using an adsorption heat pump having one or more adsorber chambers, wherein adsorption and desorption are alternated between the adsorber chambers. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
