Simulation of filter efficiency and pressure drop using fiber size distribution

M. Wist*, M. Schroers, F. Schmidt, University Duisburg-Essen (UDE); T. Engelke, D. Kasper, E. Däuber, Institute of Energy and Environmental Technology e.V. (IUTA), Germany

Conference Session: G08 - Poster I - 2023-02-15 - 14:45

Since 2018, air filters for general ventilation have to be classified and the performance parameters pressure drop and fractional efficiency determined in accordance with ISO 16890. The introduction of this guideline also has an impact on regulations that (still) refer to filter classes according to EN 779. For example, there are different recommendations at national (VDI 6022) and international (Eurovent 4/23) levels for the selection of those air filters depending on the outside air quality and type of use of the building in order to achieve the required supply air quality. The achieved supply air qualities and in particular the achieved indoor air quality in practice when using the recommended filter types have not been published yet. These questions are being investigated in a current research project (IGF 21330 N)...

Development of long-term stable filters for air cleaners based on electrically conductive tufted structures

S. Schumacher,*, B. Schunke, C. Asbach, Institute of Energy and Environmental Technology e.V. (IUTA); L. Zobel, D. Hanuschik, B. Aslan, RWTH Aachen University, Germany

Conference Session: G08 - Poster I - 2023-02-15 - 14:45

In the light of the growing awareness of air pollution and the COVID-19 pandemic, the need for improving the indoor air quality and reducing the transmission of airborne infections is steadily increasing. Air cleaners have a great potential for beneficially contributing to these aims by filtration of airborne particles. So far, most air cleaners utilize electret filters, which combine a high filtration efficiency with a low pressure drop. However, electret filters lose their non-regenerative charge over time, which reduces the filtration efficiency with increasing service life. On the other hand, there are electrostatic precipitators (ESP), which are resource saving as their collection plates can be washed, but the generation of ions by corona discharging is often accompanied by the emission of ozone. The goal of the project PureAir is to develop a filtration solution that combines the high filtration efficiency without ozone production of electret filters with the long-term stability and washability of ESP. The goal shall be achieved with...

Studies on indoor air filtration supported by simulations

T. Engelke, U. Sager*, S. Haep, Institut für Energie- und Umwelttechnik e. V., Germany

Conference Session: G09 - Poster II - 2023-02-15 - 14:45

Today, cabin air filters are part of the basic equipment of passenger cars. In addition to the highest possible filtration efficiency for particles and, in the case of combination filters with an activated carbon layer, for harmful gases, the filters must also have a low pressure drop. Another requirement is that the filters fit into the limited installation volume, which usually has a small installation cross-section. Automotive cabin air filters are offered as pleated filters to increase the filter media surface and thus reduce the effective face velocity, resulting in a lower pressure drop.

In the project "Test method for characterizing multi-effect filters for indoor air as a basis for realistic performance assessment", one aspect investigated was the extent to which the relationships between filter media structure (fiber layers and incorporated sorbents), filter geometry (number and depth of pleats), pressure drop and separation efficiency for particles and gaseous contaminants can be described with the aid of CFD simulations.

For this purpose, the pressure differences were determined as experimental tests on both prefabricated automotive cabin filters and the filter media used in them. In addition, tests were carried out to determine the particle fractional collection efficiency as well as breakthrough tests to determine the adsorption capacity. The results were...

Investigation of indoor air cleaners in realistic scenarios by experiments and three-dimensional simulations

S. Schumacher*, K. Varzandeh, T. Hülser, C. Asbach, Institute of Energy and Environmental Technology e.V. (IUTA); C. Luzzato, J. Jilesen, Dassault Systemes Deutschland GmbH, Germany

Conference Session: G12 - Indoor Air Cleaning - 2023-02-16 - 09:00

Indoor air cleaners are widely used to improve the indoor air quality and can contribute to reducing infection risks by filtration of virus-carrying droplets. There are several test standards using sealed, well-mixed and unfurnished chambers to determine the clean air delivery rate (CADR) as a measure for the cleaning performance. However, there is only limited knowledge on how the results transfer to real applications and how several air cleaners in the same room interact with each other. Moreover, the detailed distribution of cleaned air can be experimentally obtained only with low spatial resolution. Here, computational fluid dynamics (CFD) simulations can deliver additional information after a validation with experimental results. To address these aspects, we considered three scenarios typical for the application of air cleaners.

Firstly, we investigated the effect of the position of the air cleaner in a 63 m³-sized meeting room. Paraffin particles were dispersed with an atomizer and the decay of the particle concentration measured in different size ranges and at different locations without and with one or more air cleaners operating. We show that the cleaning efficacy is nearly independent of the position of the air cleaner. The cleaned air can be homogeneously distributed even in the presence of flow obstacles such as acrylic glass sheets, which are often used to prohibit direct infections between individuals. Furthermore, we demonstrate that the combination of two air cleaners operated at a lower flow setting can have the same cleaning effect as a single air cleaner at higher flow setting, but at a lower power consumption and less nuisance due to noise.

In a second step, experiments in a 200 m³-sized classroom were performed. Firstly, the most realistic situation with about 30 pupils in the room, inducing a natural airflow by their body heat and activities, was considered. In this case, particles entering the room when opening the windows were used as test aerosol. After closing the windows and operating the air cleaner, the decay rates were measured to determine the CADR. For comparison, measurements in the unoccupied room using an artificial source of NaCl particles were performed. We show that both measurements are in reasonable agreement. This means that the efficacy of an air cleaner can be determined to good approximation on site using surrogate particles and without the presence of persons in the room.

Finally, a 260 m³-sized open-plan office equipped with two identical indoor air cleaners was chosen to validate numerical simulations with experimental data. While many studies in the past have used Reynolds Averaged Navier Stokes (RANS) approaches for predicting the particle propagation, the turbulence length scales accurately captured in these simulations might not be sufficient to provide a realistic spread and mixing of particles under the effects of forced convection. Thus, here a Lattice Boltzmann Very Large Eddy Simulation (VLES) approach was applied. We investigated both the cleaning of an initially contaminated room as well as the steady state situation reached in the presence of a continuous particle source. Both simulations and measurements with salt aerosol particles were...
