Definitions
- the invention relates to a sorption element for a sorption-based air conditioning system for heating and / or cooling and / or dehumidifying a room or
- Sorption elements are the central component in air conditioning systems of this type and are usually used for air conditioning and / or dehumidification of comfort areas, in particular office or living rooms, industrial rooms or for the process air streams that are often required in industry.
- a known version of a sorption element is the sorption wheel. In this are
- the carrier material is mostly made of cellulose and has a honeycomb structure, which means a good material-surface ratio and mechanical
- Usual sorbents are silica gel, hygroscopic salts, in particular LiCl or LiBr, molecular sieves or hygroscopic metal oxides, in particular
- Airflow remove the moisture contained in it, whereby the released
- Sorption wheels rotate continuously around their longitudinal axis and are constantly exposed to two different air flows in different sections.
- One airflow supports the desired air conditioning, while a second, appropriately conditioned airflow does not provide for the respective regeneration
- Air conditioning used ensures chambers, and thus oversaturation of the
- Sorbent material prevented.
- the disadvantage is that due to the permanent humidity and temperature fluctuations,
- the sorbent on the surface of the honeycomb structure also has none optimal heat and mass transfer. This, and the proportional relationship between the amount of sorbent and its saturation lead to large-volume embodiments. As a result, the system can only be scaled to a limited extent and is further restricted in the control range.
- the object of the invention is therefore to provide a sorption element with which the disadvantages mentioned can be avoided, the heat and mass transfer optimized, the technically feasible design sizes reduced, the usable amount of the sorbent can be varied, and the resistance to oversaturation can be increased.
- the sorption element is designed as a tube part with a tube cross section and with a first and an opposite second open end, the first open end of which is delimited by a first air-permeable lattice element and the second open end of which is delimited by a second air-permeable lattice element , wherein the lattice elements are impermeable to a sorbent.
- the sorbent can be introduced between the grid elements without the aid of a carrier material.
- a disorderly accumulation of the sorbent in the sorption element by means of a bed offers the air flow in each case a particularly large acting specific surface when flowing through, which results in a greater flow resistance. This improves the heat and mass transfer, which leads to more efficient adsorption or desorption behavior.
- the sorption element has an essentially circular cross section. This advantageously allows a geometry that is optimal from the point of view of the flow technology to be present for the air flow in each case and thus a uniform distribution of the throughflow can be achieved.
- the material expenditure for the sorption element is low due to the circular cross section.
- a variant of the invention can consist in that the sorption element has an essentially polygonal, in particular rectangular, cross section.
- the manufacturing costs for a sorption element can thus be reduced. Further advantages can be seen in the costs for packaging, storage, transport and the possibility of simple assembly.
- the first open end and / or the second open end is smaller than the pipe cross section.
- the result is here advantageous effect that the reduction of the cross section can act like a nozzle. This makes it possible to apply an air stream to the So ⁇ tionsffen in such a way that it swirls. As a result, the largest possible effective, specific surface of the sorbent is achieved, from which an improved heat and mass transfer is derived.
- a maintenance opening is provided through which the sorbent can be introduced and / or exchanged in the sorption element. I have found this to be advantageous because, if necessary, soothing agents can simply be refilled, removed or exchanged. Furthermore, the maintenance opening allows the so ⁇ tion agent to be easily removed and cleaned or replaced in the event of contamination.
- a variant of the invention can consist in that the soothing agent comprises silica gel, a hygroscopic salt, in particular LiCl or LiBr, a molecular sieve, hygroscopic metal oxide, in particular Al O 3 , or a combination of the aforementioned.
- the soothing agent comprises silica gel, a hygroscopic salt, in particular LiCl or LiBr, a molecular sieve, hygroscopic metal oxide, in particular Al O 3 , or a combination of the aforementioned.
- a variant of the invention can be that the So ⁇ tionsffen is arranged as a bed.
- the advantage here is that the options which can be influenced to increase the heat and mass transfer, increase the surface with a specific effect and reduce the flow rate are used.
- the so ⁇ tion agent when the so ⁇ tion element is arranged essentially vertically, the so ⁇ tion agent is heaped up to a height which is less than the length of the so ⁇ tion element. This ensures that turbulence can spread spatially. Furthermore, this version offers the possibility of adapting the amount of the soothing agent to the desired air conditioning. This is advantageous since it also increases the scalability and, as a result, the controllability.
- the soothing agent can be fluidized / swirled by an air stream, in particular coming from below. It is advantageous that the specific acting surface of a fluidized bed is significantly higher than with a homogeneous flow through a bed or even a conventional So ⁇ tionsrad with carrier material. This leads to a further increase in heat and mass transfer.
- the invention further relates to a so ⁇ tion system for a so ⁇ tions based air conditioning system for dehumidifying and / or heating and / or cooling a room or an air flow.
- a known so ⁇ tion system is the So ⁇ tionsrad with carrier material on which the So ⁇ tionssch is applied.
- the disadvantage of this system is that, due to the frequent fluctuations in temperature and humidity, the So ⁇ tionsffen detaches from the carrier material and this, especially after repeated oversaturation, is destroyed due to water separation.
- the problem of a so ⁇ tion system is therefore to avoid the disadvantages mentioned above and to further develop the system in such a way that it can be operated profitably and continuously with acceptable sizes and is designed to be controllable accordingly.
- the so ⁇ tion system comprises at least two essentially parallel so ⁇ tion elements, according to one of claims 1 to 9.
- the advantage here is that, due to the spatial proximity of the suction elements, alternating treatment and / or regeneration air flow can be easily achieved without significantly influencing the size of the construction.
- the so ⁇ tion system is rotatable about an axis substantially parallel to the longitudinal axis of the so ⁇ tion system and / or can be moved normally to its longitudinal direction. This advantageously allows the supply and / or discharge of the different air streams to be rigid. The different loading of the individual So ⁇ tion elements takes place through the movement of the So ⁇ tion system itself and thus significantly simplifies the technical implementation.
- the invention further relates to a method for a so ⁇ tions-based air conditioning system for dehumidifying and / or heating and / or cooling a room or an air stream with a So ⁇ tionselement according to any one of claims 1 to 9, optionally a So ⁇ tionsystem according to claim 10 or 11.
- the object of the invention is therefore to provide a method for air conditioning with which the disadvantages mentioned can be avoided, in particular with regard to the economic and ecological weak points such as the absence of toxic refrigerants, the increase in service life, the increase in operational reliability and the reduction in operating costs.
- this is achieved in that the air flow to be processed is passed through at least one of the suction elements in a processing cycle, moisture being removed from the air flow to be processed.
- heat is also obtained which is used directly to heat a room and / or air stream or is returned to the air conditioning system to increase efficiency.
- a regeneration air flow in particular heated air, is passed through at least one soothing element and the regeneration cycle is started again after regeneration. This ensures that the moisture absorption property of the soothing agent is restored.
- the So ⁇ tionsstoff can thus effectively be used again until the degree of saturation is reached again in the following treatment cycle.

- Fig. 5 functional sketch of a So ⁇ tions-based air conditioning in a continuous process
- So ⁇ tion The principle of So ⁇ tion is known by two phenomena, the Adso ⁇ tion and the Deso ⁇ tion.
- Adso ⁇ tion During adsorption, moisture is extracted from an air stream flowing through a soapy agent, which heats up due to the evaporation heat generated. This effect is used in a conditioning system in the processing cycle.
- Adso ⁇ tion is reversible, one speaks then of Deso ⁇ tion.
- Deso ⁇ tion is used by applying warm air to a moisture-soaked agent, thereby removing moisture from the water. This process is also used in air conditioning systems supported by so ⁇ , namely in the regeneration cycle.
- the technical implementation takes place in a So ⁇ tionselement 1 that can be used both in the preparation and regeneration cycle.
- FIG. 1 shows an embodiment of a So ⁇ tionselement 1 with a circular tube cross section 16.
- the So ⁇ tionselement 1 is designed as a tube part, the open ends 11 and 12 of which are each provided with a grid element 13 and 14.
- the main feature of the lattice elements 13 and 14 is that they are impermeable to a So ⁇ tionssch 3, but without significantly influencing the flow of the air flow.
- the embodiment of the grid elements 13 and 14 is determined by the choice of the So ⁇ tionsstoff 3.
- the So ⁇ tionsstoff 3 is usually designed as granules
- An essential feature in addition to the material itself is the grain size. The larger the grain size of the So ⁇ tionsffen 3, the larger the mesh elements 13 and 14 can be made.
- the choice of the material used for the grid elements 13 and 14 also depends on the nature of the So ⁇ tionssch 3 and the medium flowing through. It is essential that the grid elements 13 and 14 have chemical and mechanical resistance. Chemical resistance, especially against oxidation, is a basic requirement to ensure safe long-term operation. Possible further chemical reactions that affect the operation of the air conditioning system, e.g. the quality of the air flow to be processed must also be avoided. Depending on the amount of So ⁇ tionsstoff 3, the mechanical design of the grid elements 13 and 14 can be different.
- the type of fastening of the grid elements 13 and 14 to the respective pipe part is also decisive. It is conceivable that the grid elements 13 and 14 are attached to the pipe part with easily detachable connecting elements. These can be designed as screw connections, clamp connections, tensioning mechanisms such as springs, belts or belts. Detachable connecting elements are particularly helpful when tuning the air conditioning system, since the open ends 11 and 12 of the tubular part are easily accessible and thus the introduction, refilling or replacement of the soothing agent 3 is made easier. A maintenance opening 17 can thus be realized.
- the grid elements 13 and 14 are mounted with a connection method that is only partially or not detachable, for example riveted, welded, soldered or glued, as is conceivable for larger systems, then an alternative introduction option for the soapy agent 3 must be provided. It is conceivable that an easily accessible, easy to open / close maintenance opening 17 is formed.
- the design is conceivable in the form of a flap with a corresponding closure or a screw-on cover in the upper region of the usually upright So ⁇ tionselements 1.
- Figure 2 shows another conceivable tube cross section 16, square. Depending on the design of the So ⁇ tionselements 1, the tube cross section 16 can also in other polygonal geometries be implemented, especially in rectangles of different aspect ratios. These embodiments are conceivable for air conditioning systems with predetermined space. This can be the case in systems in which the support by a So ⁇ tionselement 1 is only retrofitted.
- So ⁇ tionsffen 3 With the same design size, more So ⁇ tionsffen 3 can be introduced and offers the essential advantage that the entire surface of the So ⁇ tionsffen 3 is used for heat and mass transfer, in contrast to So ⁇ tions electrode used so far, which result in a surface loss due to the connection with the carrier material. This increases the specific acting surface of the So ⁇ tionsffen 3 and a functional failure due to destruction of the carrier material, e.g. caused by oversaturation, can be excluded.
- the So ⁇ tionselement 1 can be acted upon with air streams of different flow direction and speed.
- the difference between the length 15 of the So ⁇ tionselements 1 and the height 31 of the bed of Sko ⁇ ionsffen 3 form a chamber.
- This acts as a calming chamber in which the air flow that has already flowed through the suction agent 3 can be homogenized, in order to then be fed to the air conditioning process as a laminar flow through the second grid element 14.
- a further mode of operation of the chamber is that in the event of a reverse flow, the air flow is distributed homogeneously over the pipe cross section 16 and only then does the flow pass through the solvent 3.
- the air flow uses the entire cross-sectional area.
- a possible further form of utilization of the chamber can be that it offers space for eddies when the air flow through which the flow is high is high.
- Figures 1 and 2 show possible designs of the suction element 1 in the right-hand pictures in order to achieve the effect of the swirling.
- the necessary increase in the flow rate is achieved by reducing the pipe cross section 16.
- the advantage of this flow-through method is that, compared to the homogeneous flow through a bed, this results in an additional enlargement of the specific-acting surfaces and thereby additionally increases the heat and mass transfer.
- Silica gel a hygroscopic salt, in particular LiCl or LiBr, a molecular sieve, hygroscopic metal oxide, in particular Al 2 O 3 , or a corresponding combination are used as the So ⁇ tionsstoff 3. It is possible that the So ⁇ tionsstoff 3, usually designed as granules, is used in different grain sizes. A ratio of surface to mass of the selected soothing agent 3 that is coordinated with the system can thus be used.
- FIG. 3 shows a possible embodiment variant of a so ⁇ tion system 2, a so ⁇ tion wheel with so ⁇ tion elements 1 according to the invention.
- a so ⁇ tion system 2 consists of at least two parallel so ⁇ tion elements 1, isolated from one another, which are acted upon at the same time, in opposite directions, with the different air flows.
- the So ⁇ tionsystem 2 contains eight So ⁇ tions 1952 1. Processing and regeneration cycle can take place at the same time and thus allow constant support of the air conditioning system.
- the So ⁇ tionsrad rotates about its longitudinal axis, with the So ⁇ tions institute 1 arranged around the circumference being guided past the different air flows. This principle is easy to implement because the supply and discharge lines of the air streams can be rigid.
- Another conceivable system for continuous operation can be achieved by translating the parallel So ⁇ tions emulate 1 normal about their longitudinal axis. This is necessary if the parallel So ⁇ tions element 1 are arranged linearly next to each other.
- FIGS. 4 and 5 show two different operating methods for the permanent support of an air conditioning system. For a more detailed explanation, the following nomenclature applies in both figures: ⁇ distributor b blower c heat exchanger c 'line switchover d heat exchanger e injection f bypass g fresh air h regeneration air i supply air j exhaust air k exhaust air
- FIG. 1 A cyclic process is shown in FIG. The heart of this process is formed by two separate, spatially separate So ⁇ tions shame 1. While one So ⁇ tionselement 1 works in the processing cycle, the other is in the regeneration cycle. Regeneration takes place at higher temperatures and is therefore faster. If the So ⁇ tionselement 1 working in the treatment cycle reaches a defined limit value of the saturation with water, then regeneration air flow and treatment air flow are exchanged by the strand switchover c '. Thus, after switching, the saturated So ⁇ tionselement 1 is now supplied with regeneration air, and the regenerated So ⁇ tionselement 1 with treatment air. This alternating changeover when a defined saturation limit is reached enables the air conditioning system to be continuously supported.
- the continuous process is shown in FIG.
- the centerpiece is the So ⁇ tionsrad.
- a characteristic of this process is the rigid supply and discharge lines for the regeneration and treatment air flow.
- the application of the respective air flows takes place by rotation of the So ⁇ tionsrades, ie the connected, but isolated So ⁇ tions element 1 are rotated in the respective air flow.
- the supply and discharge lines of the air streams are designed so that a So ⁇ tionselement 1 is permanently in the treatment and a second So ⁇ tionselement 1 in the regeneration cycle, which means that the air conditioning system can be continuously supported.
- a simple example of the operation of a So ⁇ tionselements 1 or So ⁇ tionsystems 2 is the dehumidification of the exhaust air j, e.g. a swimming pool.
- the exhaust air j is passed through a processing element 1 in the processing cycle, moisture being removed from the air flow and the latter being heated by the evaporation heat released. This heated and dried air flow can now be fed directly back into the swimming pool, which considerably reduces the heating energy required.
- the air flow i can be cooled by heat exchangers c and d. Pre-humidifying the air flow i by injecting water e further lowers the temperature and also offers the possibility of reaching certain air humidities. Depending on requirements, the temperature and humidity of an air stream i can be specifically set. A change from e.g. Winter to summer operation can be easily implemented by specifically bypassing heat exchangers or injection units c, d and e with bypasses f, or e.g. flow through without cooling. The So ⁇ tionselement 1 can thus remain in the system all year round. A major advantage of the so ⁇ tions-based air conditioning system is that the So ⁇ tionsieri 1 can be combined with all tried and tested humidification systems, external cooling or alternative heat sources, in particular solar heat, waste heat from industry, condensation heat from refrigeration systems, combined heat and power.
