Rapid whole room air purification

有强有力的证据表明，由空气中的杂质引发过敏的人数正在上升。这些过敏症状与哮喘相同，可由暴露于室内环境中的一系列过敏原引发，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，这是根据净化设备所在的房间定制的。具体地说，这里的目的是明确了解空气净化率与净化装置的位置、在房间内的方位、操作条件和房间几何形状之间的联系。这种方法将是水箱实验室建模和补充理论发展的结合，最终将使快速预测能力成为可能。重点将放在能喷出净化空气的净化装置上(即“高动量”排放)。与低速喷出大量净化空气的传统设备相比，这些设备有可能减少净化整个房间所需的时间。

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.
