In response to the actual problems of how to scientifically wear masks and use air conditioners under normal conditions of epidemic prevention and control, the National Health and Health Commission organized the China Disease Control Center Environmental Institute, Vocational Health Institute and other units to separately issue the "Public Scientific Mask Wear Guidelines" and the new crown. During the pneumonia epidemic, the guidelines for the operation and management of air-conditioning and ventilation systems in office and public places were revised and adjusted to form the “Guidelines for Wearing Masks for the Public (Revised Edition)” and “Guidelines for the Management and Use of Air-conditioning in Summer (Revised Edition)”.
The "Guidelines for Wearing Masks in the Public Science (Revised Edition)" are applicable to low-risk areas. With the goal of reducing the risk of infection in the population, the public has focused on the detailed classification of how to wear masks in the prevention and control of recent epidemics and the resumption of labor and resumption of production, especially for The public guides whether to wear masks in different scenes, adjusts or adds the use of masks in key places and people such as entry and exit ports, factories, enterprises, schools, etc., and puts forward mask protection measures at this stage. At the same time, it is emphasized that medium and high-risk areas are still implemented with reference to the original guidelines.

When entering public places such as supermarkets, shopping malls, restaurants, exhibition halls / museums, gymnasiums / gymnasiums, there is no need to wear masks when there are no people gathering, good ventilation, and a social safety distance of more than 1 meter. For workers in office premises and workshops, there is no need to wear masks while ensuring effective ventilation and keeping staff at a safe distance of more than 1 meter. On campus, students and lecturers do not need to wear masks. Infants under 3 years old do not wear masks.

"Summer Air Conditioning Operation Management and Use Guidelines (Revised Edition)" stipulates the operation management and use requirements of summer office premises, public places and residential centralized air conditioning ventilation systems and split air conditioners. Compared with the original version, the Refine technical requirements. It is proposed that the equipment should be checked for normal operation before opening, and the open cooling tower, air treatment unit, air conditioning filter, etc. should be cleaned and disinfected; during the operation, the contaminated areas such as ventilation and air conditioning system condensate and cooling water should be strengthened Sanitation management, regularly clean, disinfect or replace the cooling tower equipment and components, check the toilet floor drain and other U-tube water seals and other technical requirements.
The guidelines suggest that the indoor temperature should be no less than 26 degrees Celsius. If it can meet the needs of indoor temperature regulation, the doors and windows should not be fully closed when the air conditioner is running. When using the air-conditioning system in a crowded place, to enhance indoor air flow, priority can be given to opening windows, doors, or fans to change ventilation devices, or the air conditioner must be ventilated for about 20-30 minutes every 2-3 hours of operation. For shopping malls, office buildings, underground garages and other places with large staff turnover, ventilation should be strengthened; and after the end of business every day, the fresh air and exhaust systems of the air conditioning system should continue to operate for a period of time.
In addition, the guidelines suggest that when newly diagnosed and suspected cases of new coronary pneumonia are found in the premises, the central air conditioning and ventilation system corresponding to the active areas of the confirmed and suspected cases should be immediately shut down, and under the guidance of the local disease control department, The centralized air-conditioning and ventilation system is subject to compulsory disinfection and cleaning, and can only be re-activated after undergoing hygienic inspection and evaluation.
