Manikin Coughing System（Cough Simulator）

Application

HVAC research and education, including indoor air quality evaluation, breathing and coughing exposure risk assessment in confined spaces, and cross-infection risk analysis of airborne diseases;

Medical and public health research, including simulation of pathogen-laden cough particle dispersion and airborne disease studies;

Occupational hygiene assessment, such as exposure risk evaluation of dust, PM2.5. and gaseous pollutants in workshops and factories;

Human exposure risk assessment in aerospace cabins and confined environments, including civil and military aircraft, helicopters, space stations, re-entry capsules, submarines, and deep-sea systems;

Exposure assessment and air-conditioning system optimization in vehicles and transportation systems, including buses, passenger cars, new energy vehicles, high-speed trains, subways, ships, and submarines;

Public health and military medical research in high-occupancy or densely populated environments.
