Definitions

the invention relates to a system for oxygen reduction in a target area, in particular for the purpose of fire fighting or fire prevention.
the invention relates to a system for reducing oxygen, wherein the system comprises an enclosed buffer space, which is fluidly connectable or connected to the target space for on-demand introduction of at least a portion of the room air of the buffer space in the target space.
the system has an oxygen reduction system associated with the buffer space, which is designed to set and maintain a reduced oxygen content in the room atmosphere of the buffer space compared to the normal ambient air, so that the oxygen content in the room atmosphere of the buffer space is lower than the oxygen content in the buffer space Room atmosphere of the target area.
the invention further relates to a method for oxygen reduction in a target area, in particular for the purpose of fire fighting or fire prevention.
a method for oxygen reduction in a target area in particular for the purpose of fire fighting or fire prevention.
the method is provided that in the room atmosphere of an enclosed buffer space, which is fluidly connected or connected to the target space, with the help of a buffer space associated oxygen reduction system compared to the normal ambient air reduced oxygen content to adjust and hold.
the oxygen content in the room atmosphere of the buffer space is lower than the oxygen content in the room atmosphere of the target space.
Systems for oxygen reduction of the type mentioned are known in principle from the prior art.
the present invention has the object of developing a system for oxygen reduction of the type mentioned in such a way that a smaller target area adjacent to a larger space can be efficiently, in particular cost-effectively, protected from fire.
the object underlying the invention is achieved by the subject matter of independent claim 1.
the object underlying the invention is achieved by the subject matter of the independent claim 8.
a system for oxygen reduction in a target area in particular for the purpose of fire fighting or fire prevention, wherein the system has an enclosed buffer space, which is fluidly connected to the target space or connected to on-demand introduction of at least part of the room air of the buffer space in the target area.
the system also includes an oxygen reduction system associated with the buffer space for adjusting and maintaining a reduced oxygen content in the room atmosphere of the buffer space relative to the normal ambient air so that the oxygen content in the room atmosphere of the buffer space is lower than the oxygen content in the room atmosphere of the target room.
the system has a device for the purpose of introducing room air from the buffer space into the target area.
the ratio between the volume volumes of the buffer space and the target space is selected on the one hand and, on the other hand, before introducing room air from the buffer space into the target space, the oxygen content in the room atmosphere of the buffer space is reduced in comparison with the oxygen content of the normal ambient air such that after the introduction of Room air from the buffer space in the target space, the oxygen content in the room atmosphere of the target space drops below a predetermined value and the oxygen content of the room atmosphere of the buffer space increases by at most 0.15 vol .-%.
a large space such as a warehouse
Inertization means that the oxygen content is reduced compared to the oxygen content of normal ambient air.
Such a reduction means that a fire that always requires oxygen is extinguished or the formation of such a fire is prevented.
a warehouse is therefore usually associated with an oxygen reduction system.
This oxygen reduction system ensures that in the warehouse, if necessary or permanently, an oxygen content is set which is below the oxygen content of normal ambient air.
Such a warehouse is often associated with one or more smaller premises.
These premises may be technical rooms, operating rooms of oxygen reduction plants, IT or server rooms, order picking rooms, storage rooms or the like. Such premises are usually frequented by employees, etc. in the normal case. These rooms also contain fire loads (goods, technology ...) and must be protected against fire. As a rule, a further fire prevention system is provided for this purpose. Such an additional system naturally provides further effort and costs.
the room air of the buffer space whose oxygen content is lower than the oxygen content of the normal ambient air, can be used to lower the oxygen content in the target area if necessary. Therefore, no further, the smaller space (target area) associated extinguishing system or oxygen reduction system must be provided according to the invention. Only a device for the demand-directed introduction of room air from the buffer space in the target area is necessary. This solution thus represents a significant simplification and cost reduction compared to existing systems.
the volume of the buffer space and the volume of the target space are chosen such that the buffer space is significantly larger than the target space.
the knowledge is exploited that when initiating Jardinlauft from the buffer space in the target area with optional simultaneous supply of fresh air into the buffer space for the purpose of pressure equalization and the associated increase in oxygen content in the buffer space, the oxygen content in the buffer room only increases to an extent that a fire fighting or fire prevention in the buffer room is still guaranteed.
the volume of such a buffer space is 200,000 to 600,000 m 3 and the volume of a target area 1,000 to 2,000 m 3 .
the buffer space is 100 to 600 times larger than the target space.
the oxygen content in the buffer space is lower than the oxygen content of the normal ambient air, for example 14 vol .-%.
the target area there is a normal atmosphere, ie 20.9% by volume 02.
the device for the demand-side introduction of room air from the buffer space in the target space on the other hand on the other hand and the target space on the other hand fluidly connected or connectable fan or blower.
Such a fan is used to introduce air from the buffer space to the target space when needed.
a fan or fan is much easier to implement than to provide the target space with another extinguishing device or oxygen reduction system.
multiple fans or multiple fans may be used for this purpose.
the device for the demand-wise introduction of room air from the buffer space into the target space has a device for opening an opening, in particular door, bulkhead, roller shutter or lock, which connects the buffer space to the target space as required.
an inflow of air from the buffer space into the target area can be realized or made possible by means of such an opening.
the pressure difference between the buffer space and the target space due to the introduction of room air from the buffer space in the target space can be compensated by leaks in the space envelope, if the space envelope is not too dense.
a pressure compensation device for compensating a pressure difference between the buffer space and the target space as a result of introducing room air from the buffer space into the target space.
Such a pressure compensation device may be fluidly connected or connectable to both the buffer space and the target space.
the pressure compensation device may additionally or alternatively be connected or connectable to the target space and to the outside atmosphere.
the pressure compensating means may be fluidly connected or connectable to the buffer space and to the outside atmosphere.
Such a pressure compensation device ensures that no negative pressure or overpressure occurs in the buffer space and / or the target space.
pressure relief valves can be used.
other means for pressure equalization are conceivable.
the oxygen content in the target space can be reduced to a value which corresponds to the oxygen limit concentration critical for fire extinguishment.
Such an oxygen limit concentration may be, for example, an oxygen concentration of 12 to 18% by volume.
an even lower oxygen content is achieved in the target area.
the target concentration for data centers may be an oxygen concentration of up to 13.8% by volume 02.
an oxygen reduction system is associated with the target space for adjusting and maintaining a reduced oxygen content in the room air of the target room compared to the normal ambient air.
the oxygen reduction system assigned to the target space is dimensioned relatively small, so that the oxygen content in the target space is reduced to 18% by volume.
this oxygen content does not correspond to the oxygen limit concentration but the fire risk is reduced and the inspection of the target area by persons is allowed without large requirements of the professional association or the occupational physicians.
the following method steps are provided.
room air is introduced from the buffer room into the target room.
the ratio between the volumes of the buffer space and the target space is selected and, on the other hand, before introducing room air from the buffer space into the target space, the oxygen content in the room atmosphere of the buffer space is reduced in comparison to the oxygen content of the normal ambient air such that after the introduction of Room air from the buffer space in the target space, the oxygen content in the room atmosphere of the target space drops below a predetermined value and the oxygen content of the room atmosphere of the buffer space increases by at most 0.15 vol .-%.
a pressure equalization between the buffer space and the target space is performed.
the pressure equalization between the buffer space and the target space is performed by fluidly connecting the buffer space to the target space and by fluidly connecting the buffer space and / or target space to the outside atmosphere.
the pressure equalization is realized in that the buffer space is additionally or instead fluidly connected to the target space.
the oxygen concentration is continuously or at predetermined times and / or events in the room atmosphere of the target space measured or otherwise determined, depending on the measured or otherwise determined oxygen content room air is introduced from the buffer space in the target area.
This procedure is particularly advantageous if a certain oxygen content is to be set and maintained in the room air of the target room. If a deviation in the desired oxygen content in the room air of the target room is detected here, correspondingly room air can be introduced from the buffer space into the target room or the introduction of room air from the buffer room into the target room can be interrupted or slowed down.
the presence of fire characteristics in the target area is continuously or at predetermined times and / or events monitored, wherein room air is introduced from the buffer space in the target area when at least one fire parameter is detected in the target area, while so long as room air the buffer space is introduced into the target space until the oxygen content in the room atmosphere of the target space assumes a value, the maximum corresponds to the critical oxygen extinction concentration for fire extinction.
the oxygen concentration is continuously or at predetermined times and / or events in the room atmosphere of the buffer space measured or determined differently, depending on the measured or otherwise determined oxygen content with the buffer space associated oxygen reduction system an oxygen-reduced gas or gas mixture of the room atmosphere the buffer space is supplied.
the oxygen content in the buffer space at no time exceeds a value which would lead to a fire extinguishment or fire prevention in the buffer space no longer being guaranteed.
the oxygen reduction system is accordingly operated so that effective fire prevention or fire extinguishment is achieved in the buffer room at any time.
effective fire prevention or fire fighting is thus automatically made possible also in the target area.
the solution according to the invention thus enables a highly efficient system in which only one oxygen reduction system is necessary.
FIGS. 1 to 3 Exemplary embodiments of the inventive system for oxygen reduction in a target area described.
a buffer space 1 is shown which, for example, has a volume of 100,000 to 600,000 m 3 .
This buffer space 1 is assigned a destination space 2.
the destination space 2 may be, for example, a technical room or a picking room or the like.
the target area 2 has a much smaller volume compared to the buffer space 1.
This volume of space may be, for example, a volume of 1,000 to 2,000 m 3 .
the target space 2 can be arranged directly adjacent to the buffer space 1.
the target space 2 can also be located within the buffer space 1 or spaced from the buffer space 1.
a device 3 is provided according to the invention, which is designed to connect the buffer space 1 with the target space 2 in such a way that, as required, room air can be introduced from the buffer space 1 into the target space 2.
the device 3 can be connected for this purpose, for example via a connection 6 with the buffer space 1 on the one side and the destination space 2 on the other side.
the connection 6 may be, for example, a ventilation shaft or the like.
the buffer space 1 is also assigned an oxygen reduction system 5.
the oxygen reduction system 5 can be arranged within the buffer space 1. Furthermore, the oxygen reduction system 5 can be arranged directly adjoining or at a distance from the buffer space 1. In any case, the oxygen reduction system 5 is designed to lower the oxygen content in the buffer space 1 compared to the oxygen content of normal ambient air. This reduction is done in such a way that in the buffer room 1 an effective fire prevention or fire fighting is achieved.
the oxygen content to be set in the buffer space 1 depends strongly on the goods or goods or objects provided in the buffer space 1. As a rule, an oxygen concentration of between 12 and 18% by volume in buffer space 1 is set. However, it is also conceivable that a lower oxygen concentration in the buffer space 1 is set.
the oxygen content of the room air in the buffer space 1 for example, by a sensor 7.1, as in Fig. 3 shown to be measured. If the sensor 7.1 registers that the oxygen content of the room air in the buffer space 1 deviates from a target value, the oxygen reduction system 5 can be controlled in such a way that the oxygen content is adjusted accordingly.
the invention provides that through the device 3 room air from the buffer space 1 can be introduced into the target area 2. This introduction can take place if necessary, if a fire is to be fought or prevented in the target area 2.
a sensor 7 can be provided in the target area 2, for example, which can detect a fire parameter in the target area 2. If the sensor 7 detects a fire variable in the target space 2, the device 3 is controlled in such a way that room air is introduced from the buffer space 1 into the target space 2.
the volume of space and the oxygen concentration of the buffer space 1 have a certain ratio to the volume of space and to the oxygen concentration of the target space 2.
This volume of space and this oxygen concentration are chosen so that when initiating Room air from the buffer space 1 in the target space 2 until the oxygen content in the target space (2) drops below a predetermined value, the oxygen content in the buffer space 1 by at most 0.15 vol .-% increases.
the oxygen content in the buffer space 1 slightly increases when introducing room air from the buffer space 1 in the target space 2, since during the introduction of room air from the buffer space 1 in the target space 2 fresh air into the buffer space 1, for example. is supplied by leaks on the space envelope or pressure compensation devices. This is done to establish a pressure equalization in the buffer space 1.
one or more pressure compensation devices 4, 4.1, 4.2 may be provided. These pressure compensation devices are preferably pressure equalizing valves. However, of course, other means are conceivable to ensure pressure equalization in the buffer space 1 and / or in the target area 2.
a pressure compensation device 4.1 are assigned to the buffer space 1, that between the ambient air and the room air in the buffer space 1, a pressure compensation can take place.
a pressure compensation device 4 between the buffer space 1 and the target space 2 may be arranged to allow a pressure equalization between the room air in the buffer space 1 and the room air in the target room 2.
a pressure compensation device 4.2 between the normal environment and the target space 2 may be provided, so that a pressure equalization between the normal ambient air and the room air in the target room 2 is made possible.
fresh air can be supplied to the buffer space 1, for example, by means of the pressure compensation device 4.1.
This fresh air normally has an oxygen content of 21% by volume. Due to the fact that the oxygen content in the ambient air of the buffer space 1 was initially reduced by the oxygen reduction system 5, the oxygen content increases due to the introduction of fresh air in the buffer space 1.
an oxygen concentration can be achieved, which corresponds to the critical fire extinction oxygen concentration. in this connection it may be an oxygen content, for example, between 12 to 18 vol .-%, preferably between 13 to 15.5 vol .-%, act. Lower oxygen concentrations are also conceivable.
the space volumes and the oxygen concentration of the buffer space 1 and the target space 2 are now chosen so that when introducing room air from the buffer space 1 in the target space 2, the oxygen content in the buffer space 1 by at most 0.15 vol .-% increases.
the pressure equalization device 4.1 fresh air is passed into the buffer space 1 or by a corresponding pressure compensation device 4, the room air of the target space 2 is returned to the buffer space 1.
a fan or a blower 3 For introducing room air from the buffer space 1 in the target space 2 is preferably a fan or a blower 3 is used. It is also conceivable that a door, a bulkhead, a roller shutter or a lock is provided between the buffer space 1 and the target space 2 for this purpose. If necessary, then this door or the bulkhead or the roller shutter or the lock can be opened, so that room air flows from the buffer space 1 in the target area 2.
a fan or a blower has the advantage that faster room air from the buffer space 1 can be introduced into the target area 2.
a pressure equalization means 4.2 in the target space 2 is carried out. This is particularly advantageous because otherwise the introduction of room air from the buffer space 1 in the target area 2 in the target area 2, the pressure would rise sharply and thus the structural integrity of the target space 2 could be compromised.
the oxygen content in the target area before introduction of room air from the buffer space 1 into the target space 2 is preferably 21% by volume.
the oxygen content in the target area 2 is permanently lowered and only if necessary, in particular for acute fire fighting, additional room air from the buffer space 1 is introduced into the target area 2.
the oxygen content of the room air in the buffer space 1 is significantly lower than that permanently reduced oxygen content in the target area 2.
the oxygen concentration in the buffer space 1 can amount to 14% by volume and in the target area 2 to 18% by volume.
the destination space 2 can be assigned a further oxygen reduction system 5.1.
the oxygen content in the target area 2 can then be further reduced by introducing room air from the buffer space 1 into the target area 2, for example to 15.5% by volume.
the oxygen reduction system 5 can also be used to lower the oxygen content in the target area 2.
the sensor 7 can be used to introduce room air from the buffer space 1 into the target space 2 in such a way that the oxygen content in the target space 2 is lowered. In this case, the oxygen content in the target space 2 is not reduced completely to the oxygen content in the buffer space 1, but merely reduced to, for example, 18% by volume. In the event of fire, further room air can then be introduced from the buffer space 1 into the target area 2, thereby further reducing the oxygen content in the target room 2.
the invention is not limited to the embodiments of the oxygen reduction system according to the invention shown in the drawings in a target area, but results from a synopsis of all the features disclosed herein.
