Abstract

This study introduces a new technique for controlling the concentration of indoor air particles. The novel technique is based on the cleaning of the induced air in the supply air diffuser. The idea of the present technique is analogous with the modern room air cooling utilizing active chilled beams. In these devices, the primary supply air flow induces a secondary air flow through a cooling coil. Now, the same idea is utilized for air cleaning purposes, i.e. the induced secondary air is allowed to flow through a special air cleaning device. The performance of the new technique was studied by using a commercially available chilled beam equipped with a unipolar air ionizer for particle charging and an electrostatic collector for particle removal. The results from the laboratory experiments indicate that at least 75 per cent reduction in indoor particle concentration can be achieved with the new technique.
