There is a desire to establish a safe and secure society against the spread of infectious diseases including the novel coronavirus disease through the reduction of the risk of infection. Mitsubishi Heavy Industries, Ltd. has been developing infectious disease control technologies and products for air conditioners used in transportation systems such as railway vehicles, ferries and large spaces. This report introduces some of the technologies under development. As virus control technologies, a virus removal method using airflow control and virus inactivation methods using physical or chemical means (UV-C, formulations, ozone, adsorbents) are described and as a visualization technology, a method of estimating the behavior of infectious materials and infection risk by simulation (CFD, epidemiological model, etc.) is described.
