Test Procedures of Mobile Air Cleaning Devices - First Experiences and Results

Abstract

The pandemic spread of the SARS-CoV2 viruses is leading to the use of new ventilation concepts in Europe. One of these options is the usage of Mobile Air Cleaning Devices. These are used as an alternative to central HVAC-systems (Heating-, Ventilation- and Air Conditioning-systems) and reduce the load of pathogens in the room. However, there are still no consistent methods for evaluating the performances of such devices. Thatswhy the effect on the pathogens, the benefit to the room, and the influence thereof on the room occupants are nearly unknown.This paper presents the measurements and results of different devices in the range of 500 m³/h to 1500 m³/h and beyond. Attention is given to the applied methods to define the different characteristics. Specifically, the parameters of volumetric flow rate, electrical power consumption, sound power, separation efficiency, effect on pathogens, room air flow, draught risk, and effects in the room show the need for development.
