Abstract: To clarify whether the “intelligent epidemic prevention channel device” of the clean air-conditioning system can meet the requirements of preventing new coronavirus and reducing the spread of virus. According to the relevant specification requirements, the on-site testing method is used to detect the parameters of the device such as wind speed, cleanliness, particle concentration at exhaust outlet, noise, average illuminance, and grounding resistance. The research results show that the particle purification effect and safety performance of the device meet the requirements, but the use comfort effect is flawed. Combined with the actual application and the development of epidemic situation, the paper proposes a plan to improve the equipment which provide ideas and basis for the development and improvement of anti-epidemic equipment.
