A novel indoor smell regulation method

Indoor smell affects human health and work efficiency. In order to reduce the impact of indoor smell on human health and work efficiency, a novel indoor smell regulation method was proposed. First, an indoor smell regulation system, including wireless sensor nodes (WSNs), a smell presenting device (SPD), and a wireless control node, was designed. Second, the number and location of WSNs were optimized by combining the computational fluid dynamics with the ant colony optimization algorithm. Third, the location of the SPD was determined according to the diffusion speed, uniformity of distribution, total number of indoor smell particles, and average smell concentration of the breathing section. Finally, experiments were conducted and the results show that the smell regulation system can quickly and effectively detect and remove the unpleasant smell and then release the pleasant smell. Generally, the smell regulation system is capable of performing an indoor smell adjustment in less than 5 min.
