Definitions

  • the invention relates to an air conditioning system for human use, in particular for living and working spaces, with a central air conditioning unit for air conditioning, blowers for conveying the conditioned room air in the area of the central air conditioning unit, at least one delivery channel for the conditioned air conveyed by the blower and at least one outlet duct with air outlet for introducing the room air into at least one assigned room to be air-conditioned.
  • air conditioning systems are also referred to as ventilation and air conditioning systems.
  • Human area denotes all kinds of common rooms for people, such as offices, living rooms, theaters and rooms in department stores, hospitals and the like.
  • the expression air conditioning system encompasses both full air conditioning systems and partial air conditioning systems.
  • thermodynamic air treatment functions namely heating, cooling, humidifying and dehumidifying and the corresponding control measures. They contain appropriate control devices.
  • the air treatment functions are reduced, in extreme cases to mere cooling.
  • the control outlay is correspondingly reduced.
  • Air-conditioning systems of the construction described and the intended purpose described are tried and tested aggregates for domestic technology.
  • the prevailing rules of air conditioning technology apply to their design and installation.
  • the air conditioning systems of the described structure and the intended purpose can, however, be improved.
  • the air conditioned in the air is not easily free of suspended matter and molecular contaminants, which are collectively referred to as pollutants.
  • the expression suspended matter here includes inorganic and organic substances, in this respect also viruses, bacteria and fungi.
  • the fan produces disturbing noises. They are usually in the frequency range from 125 to 250 Hz.
  • the so-called sound power level at the outlet of the blower increases with the blower output and in the delivery duct down to the air outlet. Nonetheless, a high sound power level at the outlet of the fan often causes disturbing sound pressure in the room into which the conditioned room air enters.
  • Sound insulation measures are also known in connection with this. - As is well known, sound insulation describes the impediment to sound propagation due to sound reflecting obstacles or appropriate materials. A measure of the size of the sound insulation is the sound insulation number or the degree of sound transmission. In order to achieve the greatest possible sound reflection, a medium must be placed in the way of the sound, the sound insulation impedance of which differs as much as possible from that of the sound-carrying medium, here the conditioned room air. The sound insulation of airborne sound is achieved for walls with a material that is as hard and heavy as possible, for low frequencies by using walls made of flexible materials or for structure-borne soundproofing.
  • sound absorption refers to the impediment to sound propagation with the aid of sound-absorbing media or special devices.
  • the degree of sound absorption is the degree of sound absorption.
  • Soundproofing is the name for building materials that are particularly suitable for soundproofing, but mostly also provide a certain level of soundproofing. Soundproofing means construction materials in which the sound propagation is subjected to a strong damping caused by sound adsorption, so that they usually have a sound absorption level of more than 10%. However, materials are also suitable as soundproofing materials, in which the losses arise due to internal friction. - The room acoustic measurement technology allows, without difficulty, to determine the design of the sound-absorbing and / or sound-absorbing components for known soundproofing or soundproofing tasks.
  • the filter devices on the one hand the sound-absorbing or sound-absorbing devices on the other hand, additively and both consuming energy.
  • the blower output must be increased accordingly, which increases the sound power level of the blower at the blower outlet.
  • the invention has for its object to provide an air conditioning system of the construction described and the intended purpose described, which in terms of cleaning and conditioning of the room air and in relation to the reduction of the disturbing sound pressure in the room in the the conditioned room air enters, meets much higher requirements than they have been able to meet up to now, and thus increases the comfort of air conditioning, and in comparison to the known measures with filtering and sound insulation or sound insulation, significantly reduced energy expenditure, in other words with improved efficiency.
  • the subject of the invention is an air conditioning system for human use, in particular for living and working spaces, with a central air conditioning unit for air conditioning, blowers for conveying the conditioned air in the air conditioning unit area, at least one delivery channel for the conditioned air from room air conveyed to the blower and at least one outlet duct with air outlet for introducing the conditioned room air into at least one associated room to be air-conditioned, one in the area between the blower and air outlet is arranged by the conditioned air flowing through the filter device, which has at least one suspended matter filter and at least one sorption filter, and wherein the filter device is simultaneously designed as a sound absorbing and / or sound absorbing device and the filters therein are designed as sound absorbing elements and / or sound absorbing elements.
  • HEPA filters are like sieves and have a mechanical effect.
  • the expression sorption filter means that adsorption and / or absorption takes place, also and in particular in the form of chemisorption. Chemical reactions also come into play in chemisorption.
  • the invention is based on the knowledge that a filter device which has at least one suspended matter filter and a sorption filter can clearly fulfill an additional function, namely can work simultaneously sound-absorbing and / or sound-absorbing.
  • the materials from which sorption filters are constructed can be selected and used so that they have a sound-absorbing effect.
  • front perforated panels or grille panels can also contribute to sound insulation, including those made of relatively heavy materials.
  • the materials used for the particulate filter have a particularly sound-absorbing effect.
  • the suspended matter filter and the sorption filter are primarily designed according to the rules of sound attenuation technology or sound insulation technology, this design for an air conditioning system of a given size and performance being easily determined experimentally with the aid of room acoustic measurement technology.
  • This interpretation according to the Regulations of the sound damping technology or the sound insulation technology surprisingly also have a good cleaning effect with regard to the specified pollutants, namely with a long operating time of the filter.
  • the filters themselves consist of the usual filter materials.
  • the filters of the filter device are designed as deflection devices for the conditioned room air, which are designed as filter walls and have flow channels between filter walls into which the room air emerging from the filter walls enters with deflection, with the sound damping or sound insulation is set by a small flow velocity of the room air in the filter walls, a flow velocity of the conditioned room air in the flow channels, which is increased by acceleration, and by the number of deflections.
  • the filter walls are preferably in two layers, made up of a suspended matter filter layer and a sorption filter layer.
  • the filters can be designed as plate filters, which form the flow channels between them.
  • the filters can also be designed as filter cartridges with a cylindrical filter wall and a central flow channel. In this respect, it can be connected to a proven embodiment, which is basically in the EP-OS 0 357 917 is described, but is particularly designed with regard to the desired sound attenuation and sound insulation.
  • the filter cartridges form, as it were, a soundproofing grille.
  • a sound attenuation grating is a grating made of sound-absorbing elements, that is to say, according to the invention, from the filter cartridges designed as sound absorption elements, the grating interspaces between these elements being, if possible, much smaller than the main wavelengths of the assigned noise level.
  • the invention is based on the knowledge that a filter device by a speed reduction, which the conditioned room air experiences when flowing through the filter walls, a subsequent deflection and by the number of deflections and by an acceleration to a relatively high speed in the flow, which is not caused by the Through the filter walls, but between the filter walls and along the filter walls, a remarkable sound damping or sound insulation can be achieved.
  • the speed differences as well as the number of deflections and the length of the flow path between the filter walls must be sufficiently large and the filter walls must not be too small. An optimizing setting of these influencing variables can easily be determined by tests, even for very different operating conditions. This also applies to the mass of the filter walls and is particularly easy.
  • the invention makes use of the fact that the mass of sorption filters compared to suspended matter filters is relatively large and also for the additional function of sound absorption or sound insulation can be used.
  • Sorption filters generally have a carrier for the sorbing substances, which has open pores, e.g. B. consists of foam. However, they can also be constructed as an open-pore, that is to say flowable bed. Since the filters are loaded with the contaminants during the operating time of an air conditioning system according to the invention, they must be replaced from time to time and replaced by virgin filters or regenerated filters. This is easy to achieve.
