Abstract

In a method for conditioning room air in vehicles, in particular ships, in which the room air is cooled or heated and the room air is conditioned in an open sorption with an absorber medium and a membrane that the solution concentration of the absorber medium for controlling the humidity of the room air is controlled and controlling the temperature of the absorber medium to control the temperature of the room air. In this way, a novel process is controlled, with which the solution concentration and the temperature of the absorber medium can be controlled simultaneously, but independently of each other.

Description

  • The invention relates to a method for conditioning room air in vehicles, in particular ships, in which the room air is cooled or heated and the room air is conditioned in an open sorption with an absorbent medium and a membrane.
  • Such methods for conditioning room air in cabins on the basis of a sorption process, for example, from DE 195 45 335 C2 and the DE 198 16 185 C1 known.
  • The invention has for its object to provide a new and particularly efficient method for controlling the temperature of the room air and the moisture conditioning of the room air.
  • The solution of this object is achieved by a method having the features of patent claim 1.
  • In a method for conditioning room air in vehicles, in particular ships, in which the room air is cooled or heated and the room air is conditioned in an open sorption with an absorber medium and a membrane, it is essential to the invention that the solution concentration of the absorber medium for controlling the humidity the room air is controlled and that the temperature of the absorber medium is controlled to control the temperature of the room air. By controlling the absorber medium, namely, once the solution concentration control and once the temperature control, both the temperature and the humidity of the room air are controlled. This makes a particularly simple and effective method possible. Preferably, the solution concentration and the temperature of the absorber medium are controlled simultaneously but independently. As a result, this adjustment can take place in one method step, which makes possible a particularly fast and simple reaction and adaptation to changing external conditions or requirements in the interior. Preferably, a control of the solution concentration and the temperature of the absorber medium taking into account the temperature and the humidity of the room air. Preferably, therefore, a control is provided in which, depending on the desired result, ie the temperature and the humidity of the room air, the solution concentration and the temperature of the absorber medium is regulated.
  • In a preferred embodiment of the invention, the sorption process takes place in a plurality of air conditioning units. These are distributed in the vehicle or the ship. For ships, there may well be 40, 50 or even more different air conditioning units distributed within the ship. In a preferred embodiment of the invention several air conditioning units are connected to a common supply device, from which the air conditioners are supplied with the absorber medium. In this case, several utilities can be provided in different areas. In a particularly preferred embodiment, only a single supply device is provided, which supplies all the air conditioning units of the vehicle. The supply device preferably has a regenerator, in which in particular the solution concentration, but also the temperature of the absorber medium is controlled. The water-laden absorber medium is preferably first fed to the regenerator and then from the regenerator to a heat exchanger and then fed back to the sorption process. In this way, in addition to the control of the temperature in the regenerator additional heat energy can be introduced via a heat exchanger in the air conditioning process. As a result, the use of available in other areas waste heat is possible, whereby a particularly good energy efficiency is achieved. There is also the possibility of resorting to energy in the guided out of the ship, recirculated room air energy and supply this room air to a heat exchanger and to cool or heat the absorber medium with the recirculated room air in a heat exchanger.
  • In another preferred embodiment of the invention, the absorber medium is "loaded" with water in the sorption process and the water-laden absorber medium is fed to a regenerator and the water is expelled in the regenerator by a thermal process. With such a thermal process, the process can be carried out particularly easily. In addition, the method is particularly energy-efficient feasible in this way, since waste heat from other areas of the vehicle can be used. For expelling water from the water-laden sorbent while a thermal evaporator is preferably heated with a medium. For this purpose, thermal energy can be used from another power source, for example from a drive or from a generator. Alternatively, the water can be separated from the water-laden absorber medium by means of mechanical methods, for example with an osmosis process.
  • In a preferred embodiment of the invention, the separated from the absorber medium water is fed to other processes. As a result, the method as a whole is particularly resource-saving feasible. In another preferred embodiment of the invention is in certain intervals, preferably continuously, checked whether sufficient thermal energy for carrying out the process, ie for expelling the water, is available and that when there is insufficient energy available, the water-laden absorber medium is cached in a tank. Preferably, at a time when sufficient energy is available, the cached water-laden absorber medium is returned to the regenerator. This also results in a particularly high energy efficiency, since the operation of this air conditioning method is almost exclusively possible with waste heat. In a preferred embodiment of the invention, absorber medium is supplied in a corresponding amount to the sorption process when removing water-laden absorber medium from a reservoir for regenerated absorber medium. Preferably, a hygroscopic liquid is used as the absorber medium. In particular, this could be an ionic liquid characterized by non-corrosive and odorless properties. In particular, it is a saline solution. It is possible to constructively combine the different memories and to operate a common memory as stratified memory.
  • In another preferred embodiment of the invention, in the case of cooling the room air at night, that is to say at a generally lower outside temperature, water-laden absorber medium is temporarily stored in a memory. This comparatively cold water-laden absorber medium is then supplied to and mixed with the water-laden absorber medium then produced on the day when the temperatures are higher, so that the water-laden absorbent medium fed to the regenerator is cooled during the day, thereby applying less energy to the heat exchanger following the regenerator must be to cool the absorber medium. In the opposite case, ie if the room air does not have to be cooled but heated, the processes are reversed or the water-laden absorber medium produced during the day is temporarily stored in a buffer and fed to the regenerator at night.
  • The invention will be further explained with reference to an embodiment shown in the drawing. The sole figure of the drawing gives an overview of the inventive method.
  • With 1 an air conditioner is characterized, which conditions the air in a vehicle. In large vehicles, a plurality of such air conditioners 1 used. On the right with 2 marked side is the vehicle inside indicated. So there is the room air. On the left with 3 marked side is the outside shown. From there comes the supply air or the exhaust air is on the outside 3 issued. Furthermore, a regenerator 4 , a heat exchanger 5 , a storage for water 6 , a reservoir for water-laden absorber medium 7 and a regenerated absorber medium reservoir 8th intended.
  • From the outside 3 Room air M1 becomes the air conditioner 1 fed and conditioned there in an open sorption process. In this case, typically a drying by membrane dehumidification and also a cooling or heating. When heating is often a humidification of the air. From the air conditioner 1 the room air M1 is then the vehicle on the side 2 fed. Conversely, on the vehicle side exhaust air M2 on the air conditioner 1 to the outside 3 issued. It can in the air conditioner 1 Also, a heat exchanger may be provided with the later again influencing the absorber medium is possible. A not uncharacteristic temperature constellation, in which a cooling of the room air takes place, could look like that outside air with a temperature of 32 degrees Celsius and a relative humidity of 90% in the air conditioner 1 is conditioned so that in the vehicle interior, the room air M1 is provided with a temperature of 20 degrees Celsius and 50% relative humidity. From the vehicle interior then the exhaust air M2 with a temperature of 23 degrees and a relative humidity of 60% through the air conditioner 1 and passed there a heat exchanger to the outside and then reaches the outside with about 26 degrees Celsius and 70 relative humidity.
  • At the with 10 marked point is the water-laden absorber medium S2 from the air conditioner 1 dissipated. Since the membrane dehumidification was carried out with the aid of the absorber medium, the absorber medium S2 here is water-laden. The temperature Tc of the absorber medium S2 is also comparatively high. This absorber medium S2 becomes the regenerator 4 fed. In the regenerator 4 the water-laden sorbent S2 is expelled from the water. This is a medium 1 used with a high temperature Tb, with which a thermal evaporator is operated. The medium 1 is then discharged again at a lower temperature Ta. The medium 1 is in particular a heated by waste heat liquid whose thermal energy is used in this process. From the regenerator 4 becomes in the figure the right in the line area 11 regenerated absorber medium S1 back to the air conditioner 1 fed. It passes through a heat exchanger before 5 in which with the help of a medium 2 the regenerated medium is either heated or cooled in accordance with the requirements for the temperature in the room air M1. That in the regenerator 4 from the water-laden absorber medium S2 expelled W1 water is in storage for water 6 stored and can then be fed to other processes. Is in the regenerator 4 not enough energy available, so is medium 1 insufficient to supply thermal energy, the water-laden absorber medium becomes a reservoir for water-laden absorber medium 7 cached. If enough energy is available again, then the reservoir for water-laden absorber medium can 7 this again brought into the process and the regenerator 4 be supplied. Parallel to this there is a reservoir for regenerated absorber medium 8th from which regenerated absorber medium is introduced into the circuit when water laden absorbent medium is withdrawn from circulation and into the reservoir 7 is directed. When re-importing water-laden absorber medium from the store 7 in the circulation is in the regenerator 4 generated regenerated absorber medium S1 in the memory 8th resumed. In the air conditioner 1 a heat exchanger is also provided, in which the exhaust air M2 depending on the requirement of the temperature of the regenerated absorbent medium S1 prior to delivery to the outside 3 cooled or heated, and thus the regenerated absorber medium in a heat exchanger in the air conditioner 1 is tempered.
  • For the temperatures shown in the drawing, Ta <Tb <Tc. This describes the case of cooling. It is both a cooling and a heating of the room air possible. In the figure is only an air conditioner 1 shown. However, this is to be understood that a plurality of air conditioning units are present, from which water-laden absorber medium S2 the same regenerator 4 is supplied. At a regenerator 4 , Heat exchanger 5 , Storage for water 6 , Storage for water-laden absorber medium 7 and regenerated absorber medium storage 8th can use a variety of air conditioners 1 connected and operated with them.
