Air purification unit and tension between geometry, effect and pressure loss.
Today, clean air is an increasingly valuable commodity and its supply is a growing concern. The demand for clean air is particularly high in the clinical, pharmaceutical and semiconductor industries. There is also a growing demand for hygienic air in controlled domestic ventilation systems.
For this reason, air supply systems are increasingly being fitted with filters with very small mesh sizes in the filter material. This results in a relatively high air resistance, which has to be compensated by additional fan power.
This is where the GESA – Air Disinfection project comes in, with the aim of developing an air purification unit that can be used decentrally, has low pressure losses and is therefore suitable for retrofitting to existing systems. This will be achieved by by using a special disinfectant.
The aim of the project is to develop the design of the required mixing unit and the design of the biofilter required to neutralise the disinfectant. Numerical flow simulations (OpenFOAM) will be used to predict the effects of flow and evaporation of the disinfectant.
