Research on air purification technology of fan-coil units under epidemic conditions

After the outbreak of COVID-19, the issue of air purification of fan-coil units once again attracts great attention in the air conditioning field. Introduces the relevant provisions of national standards concerned, expounds the research progress and current situation in China, and presents a developed air filter for the fan-coil units. The test results show that the filter not only achieves high efficiency and low resistance, but also has the function of inactivating virus and killing bacteria. Its dimensions are also suitable for fan-coil unit systems of various buildings. It could significantly improve indoor air quality during the epidemic period and during normal times.
