    Description: The present invention relates to a transmitter and storage block for sensible and latent heat, as well as to forced flow materials of a fluid through a plurality of channels. The transformer and storage block is alternately flowed through by a high potential fluid (temperature, substance concentration) and a fluid with low potential in countercurrent. This transformer and storage block is also known as a rotary heat exchanger with sorption or as a transfer storage and is e.g. used for regenerative heat and moisture recovery in ventilation and air conditioning systems.
    There are several generic transformers and storage of heat and substances known.
    Patent EP 0 957 320 Heat exchanger element, EP 1 796 819 Production of wound storage material for rotary heat exchangers and DE 10 2005 003 543 Moisture and / or heat exchange device, e.g. Platten¬ heat exchanger, sorption rotor Adsorptionsentfeuchtungsrotor od. Like. Describe Wärmerückgewinnungselemen¬te made of thin-walled bands, once smooth and once wavy. These sorbent-coated ribbons are wound into a rotor. Disadvantages of this design are the poor heat transfer in relation to the gross strip surface and the unfavorable channel shape. The air channels are formed by the 2 bands. Both junctions of these bands produce relevant shares of unused surfaces. In this channel corner, the lavage at laminar flow is incomplete. This leads to unwanted mass transfer, e.g. Odors, from the exhaust air to the supply air. Especially with a small hydraulic diameter, these disadvantages are pronounced. These canals are also unfavorable to the fouling behavior of the heat exchanger. When using metallic bands, e.g. Aluminum, with the material thickness necessary for heat storage, also reduces the efficiency due to the axial heat conduction.
    The patent DE 10 2011 0 011 181 heat and / or moisture exchange element describes a Plattenwär¬meübertrager as a changeover memory. Thin-walled plates or strips with plastic spacer strips are stacked and glued to a heat exchanger. The moisture exchange takes place via the condensate phase during Abkühlzyklus.Nachteile this embodiment are the low moisture efficiency, especially at a low condensation potential, as well as the cost of materials for the achievement of a pressure-stable heat exchanger. In a wet exchange with free water has the disadvantage that water-soluble substances and odors are transmitted. In this embodiment, measures for the condensate drainage and icing necessary. The pressure loss is not advantageous because of the many spacers and the unfavorable channel shape.
    The above also applies to the known designs with spirally rolled-up bands.
    Patents WO 2004 113 816 honeycomb body for thermal exhaust gas treatment, KR10 2012 025 057 Con¬tinuity turning type regenerative heat exchanger and CN 000 101 898 498 Evapuration type describe ceramic transformer with honeycomb channels for fluids with high temperatures and for substances with corrosive properties. Ceramics are suitable for the mass transfer of e.g. Water in the temperature range smaller 0 ° C not suitable. The H20 stored in the pores ices up and breaks up the ceramic material during the thawing process. The moisture exchange takes place via the condensate phase. The previously described disadvantages of low moisture efficiency, odor transmission, condensate drainage and anti-icing measures also apply to this embodiment. In addition, the production of these transformers with channels with a small hydraulic diameter is expensive.
    Patent Specification CH 700 341, Helix forced-flow heat exchangers, describes a helical fluid channel having 3 channel sections for improved heat and mass transfer. The channel surface is designed with a functional layer for mass transfer. This embodiment describes an advantageous embodiment for high specific transmission power. However, the production of the helical channels is quite laborious and justified only for applications in which a high power density is required.
    The invention has the object to provide an improved embodiment of a generic regenerative Übertrager¬und memory block. In particular, for the embodiments in which the channels with a hydraulic diameter of less than 3 mm are necessary, the specific transmission capacity should be improved and the undesired mass transfer, e.g. Odors, to be reduced.
    The transformer and storage block according to the invention is characterized in that the channels have a geometry optimized for the application and manufacture, and the channel walls are produced by at least one functional layer. The transformer and memory block according to the invention does not consist of individual bands or plates with a coating, as hitherto known, but is a block of a memory material with a multiplicity of channels. The functional layers thereby generate the lost formwork for the storage material. The first functional layer is sorptively effective. The second functional layer is e.g. a binder which is tailored to the type of sorbent material and the storage material. For applications with high hygienic requirements, the starting material for the first or second functional layer may be coated with an antimicrobial agent, e.g. Silver ions or nanosilver.
    This advantageous embodiment of Übertrager- and memory block allows easy production without laborious connections of bands or plates. No spacer profiles (plate heat exchangers) or hubs (rotors) are necessary. The channel geometry can be chosen arbitrarily depending on the task and will not

    formed by deformed and stacked sheets. The functional layers may e.g. be constructed with a multi-stage Tauchverfah¬ren. In this case, the plunger consists of a plurality of rods, which have the desired Kanalgeome¬trie. In an advantageous channel shape, e.g. circular or honeycomb, no corners arise, which can be rinsed only heavy. By choosing the thickness and the spec. Heat of the storage material, the memory can be sized as required. When using plastics as a storage material, the heat conduction in the axial direction is lower than with a metallic carrier material.
