Definitions

  • the invention relates to an adsorber element according to the preamble of patent claim 1 and to a method for producing an adsorbing element according to the preamble of patent claim 15.
  • Adsorbentbasis for example: silica, activated carbon or zeolite [then molecular sieve base]
  • Adsorbentbasis for example: silica, activated carbon or zeolite [then molecular sieve base]
  • refrigerant adsorption gives off heat
  • refrigerant desorption adsorbent absorbs heat
  • Adsorbents are generally crystalline solids whose particle size is usually in the range of a few micrometers. Advantageous for use in a heat pump is a good connection of these Adsorbentpumble to a material of very good thermal conductivity, as it represents, for example, aluminum or copper.
  • adsorbent particles are generally not The use of adhesion promoters (binder materials), which adhere the particles to one another and to the metal, is necessary. These bonding agents must meet two criteria. They should not hinder the adsorption of refrigerant into the adsorbent and, more generally, should not hinder the function of the heat pump. They should also consist of environmentally friendly and economically enforceable materials.
  • the heat pump operates under pure refrigerant vapor pressure at different temperatures. Increasing the existing pressure in the heat pump leads by the presence of inert gases to a reduction in performance of the heat pump up to a complete failure. For this reason, the adsorbent layer must not release any gases for a desired service life of 15 years, i. H. in particular, the adhesion promoter (binder material) used must not release any gases.
  • metal knits metal wool
  • metal mesh being attached to metal walls, for example, by a heat pump.
  • the method is described in DE 44 05 669 Al by the same applicant as insufficient.
  • the metal mesh with zeolite is released from the metal walls during cyclic stresses.
  • the high-temperature binder Sauerfeisenzement type 8 from SeppZeug GmbH contains no alkali metal silicates, but magnesium oxide, magnesium phosphate and zirconium silicate.
  • this material is used as a binder, so massive Shrinkage cracks up. Shrink cracks generally have their cause in the decrease in volume of the solidifying suspension due to the evaporation of liquid, for example, they can often be observed in dried, loamy river banks.
  • the adsorbent layer adheres very instable to aluminum sheet and falls off with slight vibrations immediately. The same problem occurs with the high temperature binder Ceramabond from Kager GmbH.
  • This binder contains as well as the acid rice type 8 no alkali silicates, but especially corundum in fine particle size. Experiments show that adsorbent coatings made with this binder also have numerous shrinkage cracks and immediately peel off the metal at a temperature load (16O 0 C).
  • the performance and, in particular, the stability of molecular sieve layers can be improved by the use of glass wool nonwovens as likewise described in DE 44 05 669 A1.
  • a glass wool nonwoven is applied directly to metal and then glued to the molecular sieve / binder suspension.
  • a disadvantage of this approach is that such a glass wool nonwoven can be applied only in easily accessible geometries of the metal body.
  • Organic adhesion promoters have the inherent disadvantage that outgassing reactions of the organic substances within the heat pump can occur over long periods of time, which then impair the function of the heat pump. This is done against the background that the layers in the cyclic operation of the heat pump temperatures above 150 0 C from are set and organic substances tend to decompose at these temperatures.
  • a zeolite layer which is produced by the use of organic polymer binders is provided.
  • JP 63291809 A, JP 59213615 A, DE 693 20 195 T2 and DE 103 09 009 Al describe methods by which zeolites grow directly on substrates.
  • alumina substrates JP 63291809 A
  • glass JP 59213615 A
  • ceramic DE 103 09 009 Al
  • metals or metal alloys such as aluminum or steel
  • the disadvantage is that the manufacturing method can not generally be applied to all substrate materials and is very expensive.
  • moldings to be coated (the substrates) must be placed in reactors and typically maintained at high pressures and temperatures over a period of several days.
  • Just untreated and reactive aluminum as it is very advantageous for this production method, but is undesirable in heat pumps, because it can come to so-called hydrogen corrosion over a longer period.
  • water reacts with aluminum to form aluminum hydroxide and / or alumina hydroxide and / or alumina and hydrogen.
  • the formation of hydrogen is highly undesirable in a heat pump, since this gas increases the operating pressure of the heat pump.
  • the invention has for its object to improve an adsorber element or a method for producing an adsorber of the type described above.
  • metal bodies are coated by the application of a liquid, preferably aqueous suspension and a subsequent drying process.
  • a liquid preferably aqueous suspension
  • the suspension contains adsorbent particles, fibers and a colloidal binder.
  • Colloids from Greek kolla “glue” and eidos “form, appearance" are particles or droplets which are finely dispersed in another medium (solid, gas or liquid), the dispersion medium.
  • the single colloid is typically between 1 nanometer and 10 microns in size. If they are mobile (eg in a liquid dispersion medium), colloids usually show Brownian motion.
  • Both the fibers and the colloidal binder are selected from the class of inorganic, inert or substantially inert materials, so that there can be no chemical reactions and / or outgassing during heat pump operation.
  • colloidal silicon oxides or colloidal aluminum oxides / hydroxides are used as colloidal binders for the bonding of adsorbent particles.
  • Fibers are used to impart elasticity and strength to the layer and to prevent shrinkage cracks, since such may occur particularly during drying of the suspension.
  • the layer As the layer is constantly exposed to temperature changes, tensions occur between the various materials present; H. Metal, adhesion promoters, fibers and adsorbent. These substances have different thermal expansion coefficients and therefore undergo different volume and length changes when heated, resulting in the mentioned stresses. In order to achieve a permanent strength of the layer, it follows that the layer must be elastic within limits - it must be able to "breathe”. In order to obtain a certain relaxation capacity of the layer with relatively brittle materials such as glass, the particular binder material used is preferably used in fiber form.
  • fibers of different sizes can be used with particular advantage. Larger fibers impart stability and elasticity over long distances of the layer, while smaller fibers connect the individual adsorbent particles with each other and with the larger fibers and the substrate over short distances (see also FIG. 1, which schematically shows the structure of such a layer).
  • fiber materials offer two further advantages. On the one hand, a layer crosslinked by fibers is less prone to failure. If, for example, the layer is detached from the metal at one point due to heavy mechanical stress, it will nevertheless adhere to the substrate surface in its entirety, since other sites may still provide sufficient adhesion.
  • the second advantage lies in the thermal conductivity of the layer. In addition to adhesion and elasticity, this is crucial for the successful implementation of the overall concept. If fibers with a good thermal conductivity are used, the thermal conductivity of the entire layer is increased.
  • a colloidal binder is necessary as an adhesive to bond together fibers, adsorbent particles and substrate or metal surface at the molecular level. It has the advantage over common adhesives that it does not have to be organic - commercially available adhesives such as eagle owl, epoxy resin, pattex etc. - consist of organic substances with the mentioned disadvantages - nor that it completely pores the adsorbent or can partially bond. A complete bonding of Adsorbentporen is to be avoided when used in a heat pump, because so the adsorbent is prevented from adding or desorbing refrigerant.
  • One possible disadvantage of the technique shown with the aid of fibers to create a partially elastic layer is the possibly generated preferred orientation of fibers by directed shear forces during the application process.
  • Such preferred orientation can cause shrinkage cracks to occur during the drying process of the suspension.
  • the mechanical reinforcement of the adsorbent layer can only take place in the direction of the longitudinal axis of the fibers.
  • a statistical distribution of the fibers is preferable. Such a statistical distribution can be achieved largely by spraying the suspension onto the respective substrate, which leads to irregularly acting, weak shearing forces. Fibers can no longer orient themselves in this way.
  • a second way is to add a gas generator which is added to the suspension and which is present in the layer homogeneously distributed during the drying process of the suspension and leads to a statistically distributed orientation of the fibers by gas bubble formation.
  • gas bubbles escape from the still liquid suspension before drying, these lead to an irregular and statistically distributed turbulence of the suspension, as a result of which the fibers present are distributed irregularly as desired.
  • the gas bubble formation additionally leads to a loosening of the dried layer, forming cavities and channels facilitate the diffusion of water molecules, but complicate on the other hand, the heat transport within the layer.
  • the gas generator must be selected from the group of reactive and / or volatile substances, so that after the drying process of the suspension, no gas is formed which could influence the function of the heat pump. Further advantages and details of the invention are:
  • Firmly adherent layers can be obtained by intimately mixing ground fibers having an average length of about 100 microns and a diameter of 5-12 microns with adsorbent powder and adding an alumina / silica-based colloidal binder. The resulting aqueous suspension is intimately mixed again and then applied to any substrate. After a drying process, these layers adhere to different materials having a hydrophilic surface such as copper, glass, aluminum, porcelain.
  • the resulting oxygen escapes and leads to the drying of the layer to pores, which are about 50 microns in size.
  • Iron (III) chloride is given here only as an example of a catalyst which decomposes the hydrogen peroxide, there are a large number of further suitable catalysts which can be selected depending on the circumstances.
  • Other examples which may be mentioned are: MnO 2 , colloidal MnO 2 , MnCl 2 , Fe (OH) 2 , Fe (OH) 3 , colloidal Fe (OH) 3 .
  • colloidal forms of certain transition metal hydroxides / oxides may be advantageous because they have a high catalytic activity for the decomposition of H 2 O 2 , that is to say they have to be added only in very small amounts, and because they have sufficient catalyst particle size can not penetrate into the Adsorbentporen, which could lead to a reduction in performance.
