There is strong evidence that the number of people suffering from allergies triggered by airborne impurities is on the rise. These allergies, with symptoms common to asthma, can be triggered by exposure to a spectrum of allergens found in the indoor environment, such as pollen, animal dander, mould spores, dust mites, or irritants in the air, such as pollution, smoke, strong odours or chemical fumes. The overriding aim is to achieve rapid room air purification that is tailored to the room in which the purification device is to be situated. Specifically, the aim here is to develop a clear understanding of the link between the rate of air purification and the location of the purifying device, its orientation within the room, its operating conditions and the geometry of the room. The approach will be a combination of laboratory modelling in water tanks and complementary theoretical developments that will ultimately enable rapid predictive capability. Focus will be on purification devices that energetically eject purified air (i.e. 'high-momentum' releases). These devices offer the potential to reduce the time taken to purify the entire room when compared with conventional devices that eject high volumes of purified air at low velocity.

有强有力的证据表明，由空气中杂质引起的过敏人数正在上升。这些具有哮喘常见症状的过敏症可因暴露于室内环境中的一系列过敏原而引发，如花粉、动物皮屑、霉菌孢子、尘螨或空气中的刺激物，如污染、烟雾、强烈气味或化学烟雾。最重要的目标是实现快速的房间空气净化，以适应净化装置所在的房间。具体来说，这里的目的是为了清楚地了解空气净化率与净化装置的位置、其在房间内的朝向、其操作条件和房间的几何形状之间的联系。该方法将结合水箱中的实验室建模和互补的理论发展，最终实现快速预测能力。重点将放在大力喷出净化空气的净化装置上。“高势头”版本)。与以低速喷射大量净化空气的传统装置相比，这些装置提供了减少净化整个房间所需时间的潜力。
