Definitions
- the invention relates to a method for drying or drying and Cooling of at least one plate heat exchanger in a room conducted moist air, with a liquid, hygroscopic sorbent.
- Cooling systems which, however, not only for heating, but also cause a relatively high energy consumption for cooling.
- the recycling principle also has this Territory moved in.
- the escaping exhaust air depends on the season used for pre-cooling or preheating the outside air. To achieve a the highest possible efficiency, the two air flows become more strict Separation with the largest possible exchange areas.
- the plate heat exchangers often used for this work in known way according to the counter or the cross-flow principle.
- Air conditioning also includes controlling air humidity.
- the air conditioning requirements include one Reduced air humidity, which increases relatively when cooling.
- 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 reduce the moisture content of passing air by absorbing or condensing water becomes. As with any condensation process, heat is generated, 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.
- other options also play a part in the selection Factors play a role, such as environmental compatibility, toxic Influences and last but not least the price.
- Sorption systems for dehumidifying air are well known, in which the mass and heat transfer during absorption via suitable Exchange areas of packs are made.
- the saline solution is made using a suitable Spray devices distributed over the exchange surfaces and flows in counterflow in the direction of gravity.
- a pack consists of: Packings such as Raschig rings, Pall rings, Intalox saddles or Berl saddles.
- the hygroscopic salt solution By absorbing humidity, the hygroscopic salt solution diluted until it can absorb significantly less or no more water.
- Inexpensive and ecologically harmless salt solutions are based on the one-way principle used and disposed of. This applies, for example, to an aqueous one Calcium chloride solution too.
- calcium chloride is non-toxic and even fully food-safe.
- calcium chloride is much less corrosive than the health-damaging lithium chloride. With lithium chloride you can a lower dew point than achieved with calcium chloride. against, and this is Also important for economic processes, calcium chloride is essential cheaper than lithium chloride.
- calcium chloride can be used in winter maintenance Road freezing can be used in large quantities.
- liquid hygroscopic sorbents Another advantage of liquid hygroscopic sorbents is in the fact that a perfect supply of outside air into a room The supply air is kept germ-free, which is particularly the case in inhabited areas or other rooms with a special purpose is important.
- a 5351497 is a method for drying and cooling air an absorption device known, which with a liquid dehumidifier is working.
- the absorption device is in counter or cross flow of coolant and liquid dehumidifier with certain flow rates traversed. This is aimed at the upward Sprayed outlet side of the process gases and flows with dots in Fig. 1 indicated beddings, against the upward flowing process gases, down.
- the beds are arranged in layers in parallel, the spaces between them are flowed through by sprayed cooling water and cooling air.
- the inventor has set himself the task of a method and a device to create the kind of dehumidification Enable air in a simple, economical way without the usual warming-up.
- the object is achieved according to the invention in that that the air on the inlet side of a plate heat exchanger with the liquid, hygroscopic sorbent in the flow direction continuously or sprayed periodically and the heat of condensation while maintaining a practically isothermal dehumidification of the air either directly or via medium is led into the room for cooling.
- Special and further training embodiments the method are the subject of dependent claims.
- the plate heat exchanger used to carry out the method according to the invention is usually a cross-flow, but can also be a Counterflow exchanger to be known design. Must have material the requirements regarding thermal conductivity and corrosion resistance be fulfilled.
- This preferred cooling method has the great advantage that there is no cooling water drips off, further diluting the sorbent and the regeneration at most difficult and more expensive.
- the preferably saturated sorbent solution is continuous or in relatively short intervals of a few seconds to a few Minutes, expediently 10 seconds to 3 minutes, into the sorption flow channels sprayed. Due to the condensation of air humidity the sorbent is diluted, more solution flows out of the channels than is sprayed.
- Sorbent collected to desorb the absorbed Water is heated and / or the cavity above is partially evacuated.
- the process is programmed so that the one recorded during the sorption process Amount of water is expelled again.
- the concentrated in the saturated area Saline solution is cooled into the input side for reuse Spray nozzles of the plate heat exchanger passed and again returned to the cycle.
- Regeneration is essential for hygrocospic salt solutions, which reused for their environmental impact or their high price have to or want to be.
- aqueous salt solution also called brine
- the air at one Temperature of 30 to 35 ° C, especially at about 32 ° C almost isothermal dehumidified.
- the temperature fluctuations lie in a range of ⁇ 2 ° C, preferably ⁇ 1 ° C.
- an isothermal Dehumidification in the temperature range of about 32 ° C, at about 40% relative The sorbent takes on moisture, which corresponds to about 12.7 g water / kg air about half the humidity.
- the relative humidity is still 26.6%, which is about 8g Corresponds to water / kg air.
- the dehumidified air which is still too warm in relation to the room temperature, can now cooled by evaporative cooling in a second plate heat exchanger be, preferably by the special evaporative cooling described above. So the temperature can be around 5 to 15, preferably around about 10 ° C, and the desired room temperature can be reached.
- the optimal air humidity is not yet available can be at a pre-calculated temperature above the desired one Cooled to room temperature and then cooled further while maintaining the same temperature Enthalpy can be rewetted in a second heat exchanger.
- the cooling with humidification becomes clear before it is reached the dew point line is completed.
- the cooling with constant enthalpy humidification is, for example, 2 to 10 ° C., in particular approximately 5 ° C.
- the approximation to the dew point line is expedient at most about 2 ° C.
- a sorption system for Drying or for drying and cooling air at least one corrosion-resistant Plate heat exchanger with one of the sorption flow channels on the inlet side arranged spray nozzle bar or a spray nozzle matrix for the processed sorbent and one on the inlet side of the cooling air flow channels arranged spray nozzle bars for the cooling water, one Drip pan for the dripping, diluted sorbent and a treatment circuit for the sorbent with a desorption device, a cooling device and a pump.
- the plate heat exchanger is preferably constructed from plastic films. Plate heat exchangers with alternating ones are particularly suitable crossing sorption and cooling air flow channels. In contrast to metallic The plastic plates may be used as materials for the plate heat exchanger be thin due to their low thermal conductivity, for example from tear-resistant plastic films with a thickness in the range of 0.1 up to 1 mm, in particular 0.5 to 0.7 mm. With a correspondingly greater thickness these can also be provided with covered metallic reinforcements, for example foils or crossing threads.
- a sorption system 10 shown in FIG. 1 with the possibility of cooling comprises as the centerpiece for sorption-based air conditioning, a plate heat exchanger 12.
- This is designed as a cross-flow heat exchanger and constructed in modular form from plastic films.
- This type of heat exchanger is well known per se, for example from EP, B1 0449783 and WO, A1 96/22497. Because of the low susceptibility to corrosion Plastic foils preferred despite the lower conductivity compared to metal foils.
- the moist outside air 14 flows through, as indicated in FIGS. 1 and 1a parallel sorption flow channels 16 and are dried Supply air 18 is directed into a room 20, for example an occupied room. Due to the alternating arrangement between the sorption flow channels 16 Cooling air flow channels 22 also flow moist outside air 14 through the cross-flow heat exchanger 12 and occurs as heated cooling air 24 back into the atmosphere. Analogously, the cooling air flow channels 22 entering outside air 14 may also be exhaust air that heated In this case, cooling air 24 is the exhaust air.
- the plastic films 28 forming the plate heat exchanger 12 are in accordance with Fig. 1a arranged such that the flow channels 16, 22 each sealed alternately in a flow direction for the outside air 14 are.
- a wall-mounted spray nozzle bar 26 (WO, A1 96/22497) or a spray nozzle matrix 30 which sprays a liquid, hygroscopic sorbent 32 into all sorption flow channels 16.
- the sorbent 32 is an aqueous, saturated CaCl 2 solution.
- the sprayed sorbent 32 absorbs moisture from the outside air 14 and dries it, whereby heat of condensation is released.
- the atomized sorbent precipitates on the plastic films 28 and can - if still sufficiently concentrated - absorb residual moisture.
- the surface of the plastic films 28 of the plate heat exchanger 12 can be made enlarged, for example by roughening or velor coating.
- the sorption process is intensified by the enlarged surface with a layer of sorbent.
- the moisture absorption takes place predominantly through deposited sorbent 32.
- Diluted sorbent 34 also drips from the plate heat exchanger 12.
- the cooling air flow channels are therefore on the inlet side 22 (Fig. 1a) also a spray nozzle matrix or preferably one Wandering spray nozzle bar 38 arranged, it will be again in this regard expressly referred to WO, A1 96/22497.
- the incoming outside air 14 so much cooling water 36 is added that nothing drips on the outlet side, however, the plastic films 28 always remain moist.
- a trough 40 arranged for the draining dilute sorbent 34.
- the supply air 18 flows through a droplet separator 42 known per se, which prevents that droplets of sorbent 34 remain in the supply air 18.
- a treatment circuit 52 formed, which a brine / brine heat exchanger 44, a desorption device 46, a cooling device 48 and a pump 50 comprises the now again enriched sorbent 32 in the area of the plate heat exchanger 12 and thus brings back the processing circuit 52 closes.
- the desorption device 46 is in the present case as an evaporator 54 a drain 55 and a heater 56 are formed. The heating takes place with Steam, however, could also be electrical energy or on others per se known way.
- the preheated one in the middle dilute sorbent 34 is heated and by evaporating water concentrated until the value determined by the process computer is reached.
- the concentrated sorbent pre-cooled in the brine / brine heat exchanger 44 32 is in the cooling device 48, a ventilated air cooler, on a brought optimal operating temperature.
- a collecting trough is located below the outlet openings for the heated cooling air 24 58 with a drain 59 for cleaning water of the cooling air flow channels 22 arranged. These channels are washed out at the end of work (WO, A1 96/22497) cleaned.
- FIG. 2 is a sorption system with two plate heat exchangers 12, 12 ' shown, the preparation of the dilute sorbent 34 according to Fig. 1 takes place and is therefore not shown.
- the first plate heat exchanger 12 corresponds essentially to that of Fig. 1. However, flows out through the cooling air flow channels 22 (Fig. 1a) exhaust air 60 exiting space 20, which is sprayed with cooling water 36 and exits into the atmosphere as exhaust air 62.
- the sprayed, with condensed Moisture of the outside air 14 diluted sorbent 34 is from a deflection profile 64 deflected into the area above the tub 40.
- the dried outside air 14 is through a second plate heat exchanger 12 'guided and metered if necessary by spraying with cooling water 36 moistened.
- the supply air 18 entering the space 20 is therefore temperature-related air-conditioned and water content.
- Cooling water is generated at regular time intervals via the spray nozzle bar 38 ' 36 sprayed, in compliance with the above-mentioned conditions of constantly keeping the plastic films 28 (Fig. 1a), but without dripping.
- the plate heat exchanger 12 can be switched off and with the heat exchanger 12 'by in the description of Fig. 1 mentioned modes of operation are cooled and / or heated without the absolute moisture content is changed.
- the plate heat exchanger can also be used 12 'switched off and with the plate heat exchanger 12 dried or dried and cooled.
- FIG. 3 Another variant of a sorption system with two plate heat exchangers 12, 12 'is shown in Fig. 3.
- the outside air 14 becomes as above shown continuously before entering a first plate heat exchanger 12 or periodically sprayed with liquid, hygroscopic sorbent 32, the outside air 14 is dehumidified.
- the dehumidified outside air is passed through a droplet separator 42 passed to a second plate heat exchanger 12 'and there cooled.
- the exhaust air 60 from the room 20 is divided into two partial flows.
- a first partial flow is after the periodic spraying with cooling water 36 by the led first plate heat exchanger 12 and enters as exhaust air 62 in the Atmosphere out, analogous to a second partial flow 62 ', which for cooling is guided through the second plate heat exchanger 12 '.
- a so-called Mollier-h-x diagram for moist air is one Air conditioning with a sorption system 10 e.g. 2 or 3 shown.
- Humid outside air has a temperature of 32 ° C and an absolute. Humidity of 12.8 g water / kg air.
- the moist outside air of a relative Humidity of 40% is achieved by sorption in a plate heat exchanger 12 practically isothermal by means of a sprayed-in sorbent dehumidified.
- the temperature rises slightly to 34 ° C, so it remains practical isothermal and in this first step it becomes 6 g water / kg air dried.
- the relative humidity has dropped from 40% to below about 17%. With stronger cooling, this first step could easily be done are kept more precisely isothermal.
- the dehumidified and cooled air gets through passed another plate heat exchanger and humidified and cooled there.
- the temperature drops to about 17 ° C, the absolute humidity will increased to 8 g water / kg air.
- the relative humidity is now just above 60%.
- This last step takes place with unchanged enthalpy, the curve runs parallel between two enthalpy curves 66 in the Mollier-h-x diagram. Dew point line 68 with 100% relative humidity is not reached.
