Definitions

  • the invention relates to a device for conditioning of indoor air of a clean room, in particular an operating room, comprising at least one air conveyor for conveying from the clean room originating circulating air in at least one mixing chamber and at least one outside air duct for conducting conditioned outside air into the mixing chamber, wherein the outside air duct on a the end facing away from the mixing chamber is connected to a central air conditioning device by means of which the outside air can be conditioned, in particular filterable and / or sterilized and / or dehumidified or humidified and / or cooled or heated, wherein in the at least one mixing chamber, the conditioned outside air with the circulating air mixed air is mixable and the mixed air via at least one air outlet surface, starting from the device into the clean room is conductive.
  • a method and a device of the type described above have been known in practice for some time. That's how it shows DE 34 00 487 A1 a ventilation system for the recirculation mode in operating theaters, where outside air conditioned by a central air conditioning system is mixed with circulating air from the operating room to be ventilated. In this way it is possible to avoid cooling the circulating air and instead to cool only the outside air. Since the circulating air is mixed with the outside air, it is thus possible to cool it by means of the mixed air conducted into the operating room.
  • the device shown has the disadvantage that the temperature of the mixed air mixed from circulating air and outside air can not be adjusted individually.
  • the capacity of the central air conditioning system is variable, so that the outside air is cooled more or less, the set temperature is then without exception for all rooms whose outside air duct is connected to the air conditioner.
  • the possibility of individualizing the temperature of the mixed air in individual rooms by means of in the DE 34 00 487 A1 not shown given device.
  • the shows DE 20 2005 000 661 U 1 a device that relies on individual cooling modules in the respective recirculation unit in order to cool the mixed air mixed from circulating air and outside air.
  • the outside air can also be pre-cooled by means of a central air conditioning system.
  • the device shown is suitable for adjusting the temperature of the mixed air individually at each room to be ventilated by means of the circulating air. A change in the mixing ratio of outside air and mixed air is not necessary.
  • the device shown has the disadvantage that cooling modules pose the risk of germination. This is due to the fact that the heat exchanger used to cool the recirculating air flow is charged with cold water, so that the lines used for heat exchange are cooled.
  • the DE 299 16 321 U 1 shows a device in which a mixed air volume flow formed from a recirculating air volume flow and an outside air volume flow is indirectly conditioned by treating the circulating air volume flow. This is done by means of an air conditioning module, which is arranged in the region of an air inlet cross-section of the device through which the circulating air volume flow enters the device.
  • the device has the disadvantage that the air conditioning module for the circulating air has to be particularly powerful, since the circulating air volume flow to be influenced by means of this is typically very large in terms of amount.
  • the object of the present invention is correspondingly to bring about a possibility for individual temperature control of the room air of a clean room, in particular an operating room, which is not subject to the aforementioned disadvantages.
  • decentralized air conditioning module is to be understood here as meaning that this particular air conditioning module can only heat the outside air volume flow which corresponds in that with the respective individual clean room.
  • the decentralized air conditioning module is therefore not suitable, for example, to influence an outside air volume flow, which is passed to another clean room.
  • the influencing of individual room groups is likewise conceivable, with the decentralized air conditioning module being arranged, for example, in an outside air duct leading to a group of individual clean rooms.
  • the decentralized air conditioning module offers the particular advantage that a single clean room (or a room group) can be individually supplied. This is illustrated by the following example: A single operating room should be operated at a room air temperature of 26 ° C, while other operating rooms should have only a room air temperature of 22 ° C.
  • the central air treatment device so that the outside air drawn in from outside is preconditioned, for example, to 12 ° C. (either cooled or heated, depending on the weather conditions), the mixture of the conditioned outside air with the Convection then the desired temperature of 22 ° C is reached.
  • a proportion of the outside air at the subsequent mixed air volume flow is about 15%, while the proportion of recirculated air is corresponding to about 85%.
  • the temperature of the outside air volume flow can be raised decentrally by means of the decentralized air conditioning module, whereby in all the procedure only one operating room is affected, which is to have a different temperature and which corresponds to the decentralized air conditioning module ,
  • the outside air volume flow leading to the first operating room should be heated decentrally from 12 ° C to 17 ° C, while the circulating air volume flow and the mixed air volume flow are not directly influenced. Due to the increased temperature of the outside air volume flow, the temperature of the mixed air volume flow mixed therefrom and the recirculated air volume flow is correspondingly higher than in the other operating rooms whose outside air volume flow continues to have the temperature of 12 ° C.
  • the remaining operating theaters are not influenced by this individual setting of the one operating room.
  • the targeted influencing of the outside air volume flow is particularly advantageous insofar as the outside air volume flow has comparatively low air volumes.
  • the proportion of the outside air volume flow to the resulting mixed air volume flow is typically in the range of less than 20%.
  • the remaining at least 80% are correspondingly formed by a circulating air volume flow. From a technical point of view, the lower air volumes of the outside air volume flow can be significantly more easily influenced or changed than the high air volumes of the circulating air volume flow, let alone the resulting mixed air volume flow.
  • the heating of the outside air volume flow by means of an electrical heating register is particularly easy.
  • an electrical heating register for this purpose, in particular the laying of water pipes or the like, as would be necessary when using a heat exchanger, not required.
  • the installation of an electric heater is particularly easy.
  • Such an air conditioning module is suitable for influencing the mixing ratio of the conditioned outside air and the recirculated air by quantitatively influencing the outside air volume flow by means of the air conditioning module.
  • an influence on the room temperature of a single room can be achieved as follows:
  • the circulating air volume flow has a temperature of 27.5 ° C, while the outside air volume flow is 12 ° C cold.
  • the Typical mixing ratio of conditioned outside air to circulated air is approx. 15:85.
  • the desired room temperature is 26 ° C.
  • the outside air volume flow should be changed by means of the air conditioning module according to the invention.
  • a particular problem with the mixing of air flow rates with different state properties lies in a sufficient homogenization of the resulting mixed air volume flow.
  • the non-uniform temperatures of the air volume flows to be merged should lead to a homogeneously tempered mixed air volume flow after mixing, since heterogeneous temperature levels within an air volume flow involves the risk of inconsistent flow paths, since the different air temperatures lead to different local air densities. Therefore, it is particularly advantageous if the conditioned outside air volume flow is swirled by means of a mixing element arranged in the outside air duct, preferably adjoining the mixing space, so that the outside air volume flow has a turbulent flow characteristic as it enters the mixing space. Such a turbulent flow characteristic is particularly advantageous in order to achieve a good "mixing" of the circulating air volume flow and the outside air volume flow in the mixing space.
  • the mixing chamber In addition to the pure "turbulence" of the outside air volume flow before it enters the mixing chamber, it is also advantageous to accelerate the conditioned outside air volume flow by means of a nozzle element arranged in the outside air duct, preferably adjoining the mixing space, so that the outside air volumetric flow flows as far as possible into the mixing space. In this way, it is ensured that the outside air volume flow can reach substantially any point of the mixing space and the circulating air flowing into the mixing space as it flows through the mixing space in each case comes into contact with the outside air volume flow and is mixed with it. Due to the higher flow velocity of the outside air volume flow, the mixing capacity of the circulating air volume flow with the outside air volume flow is correspondingly increased.
  • the underlying object is achieved on the basis of a device of the type described above by at least one decentralized air conditioning module, by means of which an outside air volume flow formed by the conditioned outside air can be heated, wherein the air conditioning module is preferably formed by an electrical heating coil.
  • the inventive method according to claim 1 is particularly easy to implement by means of this device.
  • the object is solved from a device-technical point of view by at least one decentralized air conditioning module, by means of which an outside air volume flow formed by the conditioned outside air can be influenced in quantity, wherein an amount per time of flowing from the outside air duct into the mixing chamber outside air volume flow is adjustable and wherein the air conditioning module preferably is formed by a volume flow controller.
  • the underlying object can be achieved both by means of the air conditioning module for heating the outside air volume flow be solved alone by means of the air conditioning module to the quantitative influence of the same. Furthermore, a combination of both is conceivable.
  • the device according to the invention has a mixing element, preferably in the form of a swirl element, which is arranged in the outside air duct, preferably in an end section of the outside air duct facing the mixing chamber, and by means of which the outside air volumetric flow can be swirled before it enters the mixing chamber.
  • a mixing element preferably in the form of a swirl element, which is arranged in the outside air duct, preferably in an end section of the outside air duct facing the mixing chamber, and by means of which the outside air volumetric flow can be swirled before it enters the mixing chamber.
  • the device according to the invention has a nozzle element arranged in the outside air duct, preferably adjoining the mixing space, by means of which an inflow depth of the outside air volume flow into the mixing space can be adjusted.
  • the outside air volume flow can be adjusted so that it "deep” penetrates into the mixing chamber and thus ensures that it is well mixed with the circulating air volume flow.
  • the outside air duct is connected to an air inlet cross section of the mixing space, which is arranged in a wall of the mixing space. That is, the outside air duct preferably does not protrude into the mixing space and thus avoids blocking or obstruction of an air flow flowing into the mixing space. The latter would result in an undesirable pressure drop in the mixing chamber. Consequently, it is advantageous if the outside air duct directly to the respective room boundary element, on the air inlet cross section is arranged, ends and this particular does not penetrate.
  • FIG. 1 A first embodiment, which is in FIG. 1 1, an apparatus 1 according to the invention, comprising an outside air duct 2, a mixing chamber 3, an air conveyor 4, a clean room 5, a recirculating air duct 6, an air outlet surface 7 and two decentralized air conditioning modules 8, 9, wherein a first air conditioning module 8 from an electric heating and the second air conditioning module 9 are formed by a volumetric flow controller.
  • the outside air duct 2 is connected to a central air conditioning device 10 at an end facing away from the clean room 5 .
  • This is adapted to be preconditioned by an outer region sucked outside air 11, typically filtered outside air, loaded or dehumidified and heated and / or cooled.
  • the air conditioning device 10 has two filter elements 12, an air conveyor 13, a heater 14 and a cooling register 15 . Air flowing in from the central air conditioning device 10 into the outside air duct 2 is referred to below as conditioned outside air 16 .
  • the circulating air 17 is filtered by means of a filter element 18 connected upstream of the air conveying device 4 .
  • the conditioned space outside air 16 is supplied to the mixing chamber 3 , which is conveyed by means of the air conveyor 13 of the central air conditioning device 10 .
  • the circulating air 17 and the conditioned outside air 16 are mixed in the mixing chamber 3 to form mixed air 19 and flowing from the mixing chamber 3 into an air outlet space 20 .
  • the mixed air 19 flows through the air outlet surface 7 into the clean room 5 , wherein the mixed air 19 is filtered again by means of a filter element 21 .
  • the high demands on air purity that are placed on the clean room 5 can be well maintained.
  • a mixing element 23 is arranged in the outer air channel 2 in the form of a swirl element.
  • This mixing element 23 causes an outside air volume flow formed by the conditioned outside air 16 to be swirled before it flows into the mixing space 3 , so that it has a turbulent flow characteristic.
  • This turbulence is particularly suitable for achieving a good mixing of the conditioned outside air 16 with the circulated air 17 , so that a mixed air volume flow formed by the mixing air 19 is particularly homogeneous and, in particular, there are no local temperature differences in the mixed air volume flow.
  • the device 1 By means of the device 1 according to the invention, it is particularly easy to influence a temperature in the clean room 5 independently of other clean rooms, which are also connected to a main branch 24 of the outside air duct 2 .
  • This is achieved by means of the decentralized air conditioning module 8 and / or by means of the decentralized air conditioning module 9 , both of which are arranged in a secondary branch 25 of the outside air duct 2 , which is connected exclusively to the clean room 5. All state or quantitative changes of the outside air volume flow formed by the conditioned outside air 16 , which are caused by means of the air conditioning modules 8, 9 , therefore affect exclusively the clean room 5 .
  • Other connected to the main branch 24 of the outside air duct 2 spaces are not affected by these changes.
  • the air conditioning module 8 in the form of the heating register can be used to change (again) a temperature of the conditioned outside air 16 after such a change has typically already taken place by means of the central air conditioning device 10 .
  • the air conditioning module 9 in the form of the volumetric flow controller can finally be used to regulate an amount per time of the conditioned outside air 16 flowing into the mixing chamber 3 .
  • a temperature of the mixed air 19 is thus influenced indirectly by influencing a composition of the mixed air 19 from recirculated air 17 and conditioned outside air 16 .
  • FIG. 2 Another device 1 ' according to the invention starts FIG. 2 out.
  • the auxiliary branch 25 of the outside air duct 2 is fanned out into four individual ducts 26 , each of the individual ducts 26 being connected to its own mixing space 3 , in which the conditioned outside air 16 flowing in the individual ducts 26 is mixed with the circulated air 17 originating from the clean room 5 ,
  • All four mixing chambers 3 shown in this embodiment are connected to a four-part air outlet space 27 , which is designed as a modular TAV outlet for an operating room.
  • both a heating coil and a volumetric flow controller are arranged in the secondary branch 25 of the outer air channel 2 .
  • All state and / or quantitative changes in the outside air volume flow from conditioned outside air 16 by means of the air conditioning modules 8, 9 have an effect on all four mixing chambers 3 , wherein all mixing chambers 3 are assigned to a clean room 5 , which is here formed by an operating room.
  • FIGS. 3a to 3d Different versions for the connection of the outside air duct 2 to the mixing chamber 3 are shown schematically.
  • FIG. 3a shows the mixing element 23, which is arranged outside the mixing chamber 3 and causes a turbulence of the conditioned outside air 16 before it flows into the mixing chamber 3 . As already explained above, this results in a mixing effect of the circulated air 17 with the conditioned outside air 16 .
  • the example according to FIG. 3b the outside air channel 2 out through a wall 28 of the mixing space 2 into an interior of the mixing chamber. 3 In this way, it is ensured that the outside air volume flow completely opens up the mixing space 3 and that mixing with the circulating air 17 is ensured.
  • the embodiment is disadvantageous insofar as the outside air channel 2 projecting into the mixing chamber 3 constitutes a flow obstacle for the air flow, so that an undesired pressure drop occurs in the mixing chamber 3 .
  • nozzle elements 29 according to the exemplary embodiment in FIG Figure 3c used. These have a reduced flow cross-section with respect to the air inlet cross-section 22, which connects the outside air channel 2 with the mixing chamber 3 . This leads to a flow velocity of the outside air volume flow increasing, as a result of which the penetration depth of the outside air volume flow into the mixing space is increased.
  • Another variant for the design of nozzle elements 29 is 3d figure can be seen, here again the outside air duct 2 is guided into the mixing chamber 3 .
