Definitions

  • the invention relates to a device for the air conditioning of rooms, consisting of storage for the absorption of moisture-absorbing granules, a heating device for drying moist granules, a cooling device for extracting heat from heated granules and a humidification device for extracting heat from the air flowing through the storage unit, and from the heating and cooling medium supplying pipelines and the accumulator with the piping connecting the room to be air-conditioned, a blower for the air to be air-conditioned and valves.
  • Such a device has become known for the air conditioning of several rooms located in a building and for the air conditioning of swimming pools.
  • the granulate of each store is stored in a separate container.
  • the process of air conditioning takes place in such a way that a mixture of room air and fresh air is passed through a store filled with adsorbent material, moisture being removed from this air mixture, as a result of which the granulate heats up.
  • This is through in coils Cooled coolant led through the memory.
  • the dry and relatively cool air thus obtained is humidified with water in a humidifier, heat being removed from this air by the evaporation of the water. As a result, it can be used to cool rooms.
  • the granules which become increasingly moist in the course of this process, have to be regenerated after some time, which is done by heating expelling water from the granules. If electrical energy is used for this heating, the night hours are used for this, where cheap night electricity is available, while during the day the energy stored as dryness at night is taken from the storage tanks. In most cases, more than two storage facilities are provided in order to have sufficient energy storage capacity available for buildings.
  • the invention is based on the knowledge that, where room cooling is required on certain days of the year, relatively cheap heat is also available through solar energy if water is heated by this energy.
  • the invention avoids the disadvantages of the prior art. It is the object of the invention to create a simple and space-saving device with simple means, which is able to carry out a single-room air conditioning with little construction effort and low energy consumption.
  • the invention consists in the fact that the accumulators are made of perforated plate sets, between which the granulate is stored and to which coils are fastened, that both accumulators are in operation at the same time, namely one accumulator in the state of drying air flowing through it with simultaneous cooling of the granules heating up during the drying of air flowing through them, the other store in the state of its regeneration by the heating medium flowing through the coils, by a three-way valve combination behind the stores for guiding the air emerging from the stores in one way in the air-conditioned Space and on the other hand is arranged on an exhaust air path, and by a further valve combination is arranged in the pipes leading to the storage heating medium and cooling medium, which leads alternately in one storage heating medium and in the other storage cooling medium, wherein a control device is provided, both of which Valve combinations reversed at the same time.
  • This device can be manufactured with very little space and is therefore particularly suitable for individual room air conditioning. It can be operated with waste heat or water heated by solar energy. The required amounts of adsorber granulate are relatively small because the device cools while working with one store and regenerates the other store at the same time. The absorption mass heated during the cooling can be cooled in a conventional manner without any problems. Since this device is preferably intended for individual room air conditioning, there is no transmission of germs and bacteria from one room to another.
  • the invention also consists in a method for operating such a device for the air conditioning of rooms, which comprises two stores for holding moisture-absorbing granules, a heating device for drying moist granules, and a cooling device for extracting heat from heated granules and a humidification device for the removal of heat from the air flowing through the store, this method being characterized in that air is simultaneously drawn into the store from the room to be air-conditioned, or a mixture thereof, that both stores simultaneously in the Operation, namely the one storage in the state of drying air flowing through it while cooling the granules heating up during the drying of air flowing through it, the other storage in the state of its regeneration by the heating medium flowing through the coils, and that this The operating state of the storage device changes from time to time, the air passing through the cooled storage device being directed into the room to be air-conditioned and the air passing through the heated storage device being directed outside.
  • This method is carried out particularly economically in such a way that the heat given off by one store during its cooling is used for heating the other store.
  • the space requirement is particularly low if the two stores are accommodated in a container and are arranged in such a way that the container is divided into three rooms on both sides of the store, one room (seen in the direction of flow) in front of the two stores and one separate room behind each the stores.
  • the container holding the two stores is divided into two parts behind the stores in the flow direction by a partition.
  • this can be achieved in a particularly simple manner if the stores in the container are arranged in a V-shape, in that the store edges touch in the middle or are connected to one another by a wall and the stores are connected to the container walls in the region of the air inlet into the container .
  • An embodiment of the memory can be designed so that the V-shaped memory enclose an acute angle between them on its inlet side.
  • the outlet valve combination can be designed in such a way that a pivotable, two-leaf flap is fitted in the container behind the accumulators in the flow direction which touches the container wall with one wing and with the other in each case the free edge of the two stores standing in the container.
  • an outlet opening for the air flowing through the accumulator is arranged in the part of the container wall which is located between the two positions of the flap wings, while the other outlet opening for the air flowing through the accumulator is arranged in the area outside and behind the movement space of the flap wing is arranged.
  • Another embodiment of the store consists in that the stores arranged in a V-shape enclose an obtuse angle between them at their entry surfaces.
  • the edges of the accumulator touch the container walls and thereby form three spaces in the container, of which the space adjoining two accumulator walls forms the air inlet and the spaces adjoining only one accumulator wall form air outlet spaces.
  • This embodiment of the memory can expediently be designed in such a way that the two air outlet spaces each have two air outlet openings, all of which are in the region of a slide with two Through openings are located, which are aligned in one position of the slide with the one air outlet opening of each of the two air outlet spaces and in the other slide position with the other air outlet opening.
  • This system works completely automatically if the control device is controlled by moisture meters arranged in the granulate.
  • this device can also work as a full air conditioning system and can be used to heat the room in winter, it is useful if a further three-way valve is arranged in the air path leading to the room to be air-conditioned, which leads the air either via the humidification device or via a bypass that bypasses the humidification device.
  • the device shown schematically in the drawing for the air conditioning of a room 1 consists of two stores 2, 3 for receiving moisture-adsorbing granules 4, a heating device 5 for drying moist granules 4, a cooling device 6 for extracting heat from heated granules 4 and one Humidification device 7 for extracting heat from the air flowing through the store 2, 3, and with pipes 8, 9 supplying heating and cooling medium, and the store 2, 3 with the pipes 10 connecting the room 1 to be air-conditioned, a blower 11 for the air to be air-conditioned and Valve arrangements 12, 13.
