Definitions
- the invention relates to a method for drying or drying and Cooling from at least one plate heat exchanger into a room directed air, with a liquid, hygroscopic sorbent.
- Refrigeration systems used which not only for heating, but also to cause a relatively high energy consumption for cooling.
- the recycling principle has on this Territory.
- the escaping exhaust air is depending on the season used for precooling or preheating the outside air.
- the two air currents are more strict Separation with the largest possible exchange surfaces passed through each other.
- the plate heat exchangers which are frequently used work in known manner after the counter or after the cross flow principle.
- Air conditioning also includes regulation of humidity.
- the demands on air conditioning include one Reduction of humidity, which increases relatively when cooled.
- the dehumidification of the outside air does not only become solid, hygroscopic materials used, but also liquid sorbents. Saturated solutions of hygroscopic salts dissolved in water lower the moisture content of passing air by absorbing or condensing water becomes. As with any condensation process, this creates heat, which however, because of the greater absorbency at lower temperatures is undesirable.
- Sorbents known per se are saturated solutions of salts of Alkali and alkaline earth metals, for example lithium chloride and / or calcium chloride. In addition to the absorption capacity also play in the selection Factors, such as environmental compatibility, toxic Actions and not least the price.
- Sorptionsvorgang For the understanding of the driving force in an absorption process in which Practice usually briefly referred to as Sorptionsvorgang, is the knowledge of Vapor pressure above the liquid level of great importance.
- a good Sorbent has a lower vapor pressure than water in air. at a greater difference, the sorption is higher.
- Sorption systems are generally known for dehumidifying air, in which the mass and heat transfer during absorption via suitable Exchange surfaces of packages takes place.
- the saline solution is determined by means of suitable Spraying devices distributed over the exchange surfaces and flows in countercurrent in the direction of gravity.
- a pack consists of Packings, such as Raschig rings, Pall rings, Intalox saddles or Berl saddles.
- liquid hygroscopic sorbents Another advantage of liquid hygroscopic sorbents is in that when supplying outside air into a room a perfect Sterilization of the supply air is ensured, which is especially true of inhabited or other rooms with a special purpose is of importance.
- the sorption wheel With a rotating sorption dehumidifier, the sorption wheel known per se, can the condensation heat generated during dehumidification which greatly reduces the water absorption of the sorbent, not sufficient be dissipated. In addition, there is the so-called drag heat through the regeneration.
- the inventor has set himself the task of a method and a device to create the type mentioned, which is the dehumidification Enable air without the usual warm-up in a simple, economical way.
- the object is achieved according to the invention, that the air on the input side of a plate heat exchanger with the liquid, hygroscopic sorbent in the flow direction continuously or periodically sprayed and the heat of condensation while maintaining a practically isothermal dehumidification of the air is continuously discharged.
- the plate heat exchanger used to carry out the process according to the invention is usually a cross-flow, but can also be a Countercurrent exchanger be known per se. Material must the requirements for corrosion resistance are met.
- This preferred cooling method has the great advantage that no cooling water drips and so the sorbent further diluted and the regeneration at most difficult and more expensive.
- the preferably saturated sorbent solution is continuously or in relatively short time intervals of a few seconds to a few Minutes, suitably 10 seconds to 3 minutes, into the sorption flow channels sprayed. By the condensation of humidity is dilutes the sorbent, it flows more solution from the channels than is sprayed.
- the diluted from the sorption flow channels dilute Sorbent collected for desorption of the absorbed Water is heated and / or the overlying cavity partially evacuated.
- the Procedure is programmed so that the recorded during the sorption process Amount of water is expelled again.
- the concentrated in the saturated area Saline solution is under refrigeration for reuse in the input side Passed spray nozzles of the plate heat exchanger and again returned to the cycle.
- Regeneration is essential in hygroscopic saline solutions which reused because of their environmental impact or their high price be or have to be.
- aqueous salt solution also called brine
- the air for the time being at one Temperature of 30 to 35 ° C, especially at about 32 ° C, almost isothermal dehumidified.
- the temperature fluctuations are within a range of ⁇ 2 ° C, preferably ⁇ 1 ° C.
- an isothermal Dehumidification in the temperature range of about 32 ° C at about 40% relative Moisture, which corresponds to about 12.7 g of water / kg of air, takes up the sorbent about half of the humidity at a final temperature of also about 32 ° C, the relative humidity is still 26.6%, which is about 8g Water / kg of air corresponds.
- the dehumidified, with respect to the room temperature still too warm air can now cooled by evaporative cooling in a second plate heat exchanger be, preferably by the above-described special evaporative cooling. So the temperature can be around 5 to 15, preferably around about 10 ° C, lowered and the desired room temperature can be achieved.
- Cooling at constant enthalpy by moistening is for example 2 to 10 ° C, especially about 5 ° C.
- the approach to the dew point line is expedient at most about 2 ° C.
- a sorption to the Drying or drying and cooling of air at least one corrosion resistant Plate heat exchanger with an input side of the sorption flow channels arranged spray nozzle beam or a spray nozzle matrix for the treated sorbent and an input side of the cooling air flow channels angeordenten spray nozzle beam for the cooling water, a Drip tray for the dripping, diluted sorbent and a treatment loop for the sorbent with a desorption device, a cooling device and a pump.
- Special and further education Embodiments of the device are the subject of dependent claims.
- the plate heat exchanger is preferably constructed of plastic films. Particularly suitable are plate heat exchangers with alternating, themselves crossing sorption and cooling air flow channels. Unlike metallic Materials for the plate heat exchanger may be the plastic plates be made thin only because of their low thermal conductivity, for example, from tear-resistant plastic films of a thickness in the range of 0.1 to 1 mm, in particular 0.5 to 0.7 mm. With correspondingly greater thickness these can also be provided with covered metallic reinforcements, For example, films or crossing threads.
- the inventive method and the associated device allow with simple means to dehumidify large volumes of air simply and inexpensively and where necessary or desirable to cool. Reaching the dew point line is avoided in all process steps. Thanks to the brine, the is either disposed of or regenerated, is also a perfect germ free the supply air ensured.
- a sorption system 10 shown in FIG. 1 with cooling possibility comprises as a core piece for sorption-assisted air conditioning a plate heat exchanger 12.
- This is designed as a cross-flow heat exchanger and module-shaped constructed of plastic films.
- This type of heat exchangers is in itself well known, for example from EP, B1 0449783 and WO, A1 96/22497.
- Plastic films are preferred despite the lower conductivity compared to metal foils.
- the moist outside air 14 flows through, as indicated in FIGS. 1 and 1a arranged in parallel sorption flow channels 16 and are as dried Supply air 18 in a room 20, for example, an inhabited room, headed.
- Cooling air flow channels 22 also flows moist outside air 14 through the cross-flow heat exchanger 12 and occurs as heated cooling air 24 back to the atmosphere.
- the in the cooling air flow channels 22 incoming outside air 14 also be exhaust air, the heated Cooling air 24 is the exhaust air in this case.
- the plate heat exchanger 12 forming plastic films 28 are according to Fig. 1a arranged such that the flow channels 16, 22 each closed alternately in a direction of flow for the outside air 14 are.
- a migrating spray nozzle bar 26 (WO, A1 96/22497) or a spray nozzle matrix 30 is arranged, which sprays a liquid, hygroscopic sorbent 32 into all sorption flow channels.
- the sorbent 32 is an aqueous, saturated CaCl 2 solution.
- the sprayed sorbent 32 absorbs moisture from the outside air 14 and dries it, releasing heat of condensation.
- the atomized sorbent is deposited on the plastic films 28 and can - if still sufficiently concentrated - take up residual moisture.
- the surface of the plastic films of the plate heat exchanger can be made enlarged, for example by roughening or velor coating.
- the increased surface area with a layer of sorbent intensifies the sorption process.
- the moisture absorption takes place predominantly by precipitated sorbent 32.
- From the plate heat exchanger 12 exits dried supply air 18, which for example still contains half of the original moisture. Further drops from the plate heat exchanger 12 diluted sorbent 34 from.
- the invention essential advantages, a higher specific dehumidification performance and a virtually isothermal dehumidification process can only be achieved when the condensation heat is dissipated optimally.
- Fig. 1 is therefore the input side of the cooling air flow channels 22 (Fig. 1a) also a spray nozzle matrix or preferably a wandering spray bar 38 arranged, it is in this respect again expressly referred to WO, A1 96/22497.
- the incoming outside air 14 is added so much cooling water 36 that the output side drips nothing the plastic films 28, however, always remain moist.
- a trough 40th for the dripping dilute sorbent 34 In the area below the outlet openings for the supply air 18 is a trough 40th for the dripping dilute sorbent 34.
- the supply air 18 flows through a known droplet separator 42, which prevents that droplets of sorbent 34 remain in the supply air 18.
- a treatment cycle 52 which comprises a brine / brine heat exchanger 44, a desorption device 46, a cooling device 48 and a pump 50 comprises the now re-enriched sorbent 32 in the range the plate heat exchanger 12 returns and thus the conditioning circuit 52 closes.
- the desorption device 46 is in the present case as an evaporator 54 with a drain 55 and a heater 56 is formed. The heating takes place with However, steam could also be powered by electricity or to others known manner.
- the mid-range, preheated Dilute sorbent 34 is heated and by evaporation of water concentrated until the value determined by the process computer is reached.
- the pre-cooled in the brine / brine heat exchanger 44 concentrated sorbent 32 is in the cooling device 48, a ventilated air cooler, on a optimal operating temperature brought.
- Fig. 2 is a sorption with two plate heat exchangers 12, 12 ' wherein the preparation of the dilute sorbent 34 according to Fig. 1 is done and therefore not shown.
- the first plate heat exchanger 12 substantially corresponds to that of FIG. 1.
- the cooling air flow channels 22 (FIG. 1a) are outflowing Exhaust air 60 exiting the space 20, which is sprayed with cooling water 36 and as exhaust air 62 exits into the atmosphere.
- the sprayed, with condensed Moisture of the outside air 14 diluted sorbents 34 is from a deflection 64 in the area above the tub 40 is deflected.
- the dried outside air 14 is passed through a second plate heat exchanger 12 'out and dosed if necessary by spraying with cooling water 36 moistened.
- the entering into the space 20 supply air 18 is thus with respect to temperature and water content air conditioned.
- the plate heat exchanger 12 can be switched off and with the heat exchanger 12 'by in the description of Fig. 1 mentioned operations are cooled and / or heated, without the absolute moisture content is changed. Likewise, the plate heat exchanger 12 'off and with the plate heat exchanger 12th dried or dried and cooled.
- FIG. 3 Another variant of a sorption with two plate heat exchangers 12, 12 'is shown in Fig. 3.
- the outside air 14 is as above shown before entering a first plate heat exchanger 12 continuously or periodically sprayed with liquid hygroscopic sorbent 32, wherein the outside air 14 is dehumidified.
- the over a mist eliminator 42 passed to a second plate heat exchanger 12 'and there cooled.
- a first partial flow is after the periodic spraying with cooling water 36 through the first plate heat exchanger 12 and passes as exhaust air 62 in the Atmosphere off, analogous to a second partial stream 62 ', which for cooling through the second plate heat exchanger 12 '.
- a so-called Mollier-h-x diagram for humid air is a Air conditioning with a sorption plant 10 e.g. shown in FIG. 2 or 3.
- Humid outside air has a temperature of 32 ° C and an absolute Humidity of 12.8 g water / kg air.
- the humid outside air of a relative Humidity of 40% is achieved by sorption in a plate heat exchanger 12 is virtually isothermal by means of a sprayed sorbent dehumidified.
- the temperature rises slightly to 34 ° C, so it remains practical isothermal and in this first step to 6 g of water / kg of air dried.
- the relative humidity has dropped from 40% to below about 17%. By stronger cooling, this first step could easily be kept even more isothermal.
- the dehumidified and cooled air is through passed another plate heat exchanger and moistened and cooled there.
- the temperature drops to about 17 ° C, which becomes absolute humidity increased to 8 g of water / kg of air.
- the relative humidity is now just above 60%.
- This last step takes place at unchanged enthalpy, the curve runs parallel between two enthalpy curves 66 in the Mollier-h-x diagram.
- the dew point line 68 with 100% relative humidity is not reached.
- Moist outdoor air has a temperature of 32 ° C and a absolute humidity of 12.8 g of water / kg of air, giving a relative humidity of 40%.
- the absolute humidity is lowered to 8 g of water / kg of air, the relative humidity has dropped to about 26%.
- the air is lowered directly to the final temperature of 20 ° C without dehumidification, the relative humidity increases to about 52%.
