 Beijing is clear that only when these places meet the requirements can the central air conditioning and ventilation system be used


1. For the centralized air conditioning and ventilation system with all air mode, the return air system shall be closed and operated with brand-new air. The places (buildings) where the centralized air conditioning and ventilation system belongs shall be operated for an extra hour before or after being opened or closed every day;

2. The air-water centralized air conditioning and ventilation system shall ensure the independent ventilation of each room;

3. The central air conditioning ventilation system equipped with air purification and disinfection device (to remove particles, gaseous pollutants and microorganisms) shall be operated in strict accordance with the product instructions during operation to ensure that the operation effect meets the requirements of national health standards.

(function(){( window.slotbydup=window .slotbydup||[]).push({id:u6056789,container:ssp_ 6056789, async:true });}) (); the disease control department proposed in the newly formulated guidelines that before using the central air conditioning and ventilation system, the operation management department of the air conditioning and ventilation system should understand the category, air supply range, fresh air intake, etc. of the central air conditioning and ventilation system. The filter, air outlet, air handling unit, surface cooler, heater (humidifier), condensate pan and other equipment and components of the operating central air conditioning ventilation system shall be cleaned, disinfected or replaced regularly. When novel coronavirus pneumonia cases were confirmed and suspected cases were found, central air conditioning and ventilation systems corresponding to the confirmed cases and suspected cases should be immediately shut down, and centralized air conditioning and ventilation systems in these areas should be immediately cleaned and sterilized. The use of central air conditioning ventilation system should also be noted: the use of central air conditioning ventilation system, should ensure that all rooms in the building air circulation and enough fresh air supply. During the epidemic period, windows should be opened first to adopt natural ventilation, and exhaust fans and other air extraction devices can be opened if possible to enhance indoor air flow. Chlorine containing disinfectant has certain corrosiveness to metal. It is suggested that quaternary ammonium salt disinfectant should be selected preferentially for metal parts that need to be disinfected. Relevant recommendations Beijing: commuters and freight drivers around Beijing should realize mutual recognition of test results Beijing nucleic acid testing institutions increased to 128 to provide services for groups and individuals source: Beijing daily client editor: Hu Shuli_ MN7479
