DD157626A1 - STERILE FILTER COMBINATION FOR PRODUCTION KEIMARMER ZULUFT - Google Patents

Abstract

The invention relates to a sterile filter combination as a component for use in ventilation systems for producing germ-free supply air. The invention is both for new projects in new buildings and old building substance as well as for retrofitting in existing ventilation systems in social and health care, such. in operating theaters, district hospitals, preterm laboratories, intensive care rooms, pharmacological rooms, working and storage rooms with sterile requirements. The object of the invention is to provide a sterile filter module with a wide range of applications and cost-effective production, higher Energieoekonomie to optimize indoor air conditions with special sterile requirements for specific spaces in social and health care and similar areas in the pharmacological industry. The inventive solution consists in the joint arrangement of a Lufterbausteine in the general sense, a suspended matter filter and UV filters and their combination separately and / or in cooperation with an air conditioning system.

Title of the invention

Sterile filter combination for producing germ-free supply air.

Application of the invention

The sterile filter combination according to the invention is preferably for the. Use in rooms of the social and health service as well as in the pharmacological industry with sterile requirements, such as in operating rooms, delivery rooms, preterm laboratories, intensive care rooms, pharmacological rooms as well as in all working and storage rooms with sterile requirements.

The use of the sterile filter combination is suitable both for the new "configuration and for retrofitting in existing ventilation systems"

The field of application concerns both the ventilation and the air conditioning of the aforementioned applications *

The need to comply with certain ambient air parameters both for technical / technological processes and for improving working and living conditions is not just for industrial and social construction in general. Meaning, but also for the social and health care with special sterile requirements in the "special sense" The use of air and klisierench.nis.chen products, especially in

a single room aeration or .. -Accommodation of new buildings "and especially in the retrofitting of existing rooms, v / o the use of central systems is not possible, failed so far because there are no satisfactory solutions for a germ-free supply air" The z .. The effectiveness of such a filter only occurs with multiple circulating air operation. At the same time, the effectiveness of such a filter is essentially determined by the wetting of the filter candles with triethylene glycol, which results in a high degree of purity Maintenance is required «

In addition, sterile filter assemblies are known which consist of combinations of HOVER filters with UY lamps. However, they are suitable for certain applications, e.g. as ceiling air outlet - sh. e.g. BGM No. 78 08 587 - designed and do not allow universal use, such as the erfindungsgeraäße combination as a building block, it allows «

The object of the invention is to develop a sterile filter combination as a building block for use in ventilation and air conditioning systems to produce germ-free supply air, the use of air and air conditioning products in the recirculation »and / or fresh air operation in social and health care including in areas of Pharmacology industry with special sterile requirements and low Y / treatment effort possible ", It is to be found such a solution that allows specifically the use of air & JQimatechnik in individual rooms (new construction and Kach armor), but also the use for central air and Air conditioning includes »

The erfindungegeraäße object is to make a sterile 'filt'erkombination as a block in different gradations,' for different amounts of air uad for use in ventilation systems for producing germ-free supply air so that according to the respective application, a separate or combined use with air and air conditioning products is possible for rooms with special sterile requirements * The structural design should also allow an economical production, low maintenance and ease of use or 'maintenance'.

The erfindungsgeinäße object has been solved such that in. A channel element seen in the air direction, a fan part _s a Schwebstoffilterteil and a UV filter part were arranged one behind the other. The UV filter preferably operates in a wavelength range of approximately 253 nm. The UV burners were arranged in the UV filter section parallel to the air direction. In the suspended matter section, both the suspended matter filters and the UV filters were arranged transversely to the flow direction. To increase the. Effectiveness of UV burners e'ind the channel inner walls of the UV filter part with a reflective layer. The individual components are brought into the channel section by means of inserts. This arrangement makes it possible to make the conditioned by an air or air conditioning product supply air by germs that the aiifbereitete air is conveyed through the fan part, the retained air in the air on the dust and dirt particles on Schwebstoffilterteil and the remaining germs in the UV Be killed filter part. Y "The dimensioning of the 'fan part, the suspended particle filter part and the UV filter part' allow both an adaptation to different air and air conditioning products and to different air flow rates, as well as a separate use without air or air conditioning product.

The use of such a sterile filter module can take place in any mounting position and is always at the end of the air gap, that is, to provide 'immediately before the supply air into the room',.

The invention will be explained in more detail below with reference to exemplary embodiments »

In the example chosen according to FIG. 2, it is assumed that a room with special sterile requirements is to be conditioned.

The circulating air 13 and / or fresh air 14 is conditioned in accordance with the requirements of the Eaumluftpara ~ meter (temperature and humidity) and the Sterilfilterkombination 1, which is directly constructed on the chimney 12, supplied by the chiller 12. The fan 5 contained in the sterile filter combination 1 further conveys the conditioned air and thereby overcomes the additional air resistances of the filter combination 1 including the supply air grid 11. In the suspended matter filter 6, dust and dirt particles, including germs thereon, are present. retained ... The changing of the filters (6, 7) is simply made possible by means of inserts 9, 10. »The thus purified and treated air enters the UV filter part 4 · In this UV filter part 4 UV burners 7 are along the air direction The UV-filter part 4 is internally provided with a reflecting layer 8 in order to increase its effectiveness. In this UV filter part 4, the remaining germs passing through the suspended-bed filter part 6 are destroyed. The replacement of the UV burners 7

as well as the performance of maintenance work by insertions 9,

The conditioned by the climatosphere 12 and the Sterilfilterkombination 1 sterilized supply air passes through the supply air grid 11 directly into the room to be conditioned ..

The not shown .Schaltung this entire Klimasterilbelüftungsanlage is eo that in the UV filter part 4 with lietzauschaltung the UV »burner 7 go into operation while the fan 5 of the fan part 2 is switched simultaneously with the fan of the climat quiet 12»

The illustration according to FIG. 1 shows a sterile filter combination according to the invention as a separate assembly consisting of the three main elements fan part 2, suspended matter part 3 and UV filter part 4 with the inserts 9 and 10 for the UV burners 7 and suspended matter filter 6 as well as the fan 5 ,

In the representation according to Pig. Figure 3 shows a sterile filter combination as a duct installation in an air handling unit shown as another application example. The connection is made to the channel section 15 in the immediate vicinity of the supply air grid eleventh

The invention achieves the following technical and economic advantages: '.

Economically favorable production base through uniform design of the basic structure with variable application possibilities.
