6.2 Dynamic Disinfection Purification Construction
6.2.1 When constructing indoor air disinfection purification projects for each scenario as outlined in Table 1, the technical standards should comply with the requirements specified in Chapter 5.2 of T/BYXT 053-2023. The equipment must meet the requirements set forth in Chapter 6 of T/BYXT 053-2023 for dynamic disinfection and purification categories.

6.2.2 Projects utilizing dynamic ion disinfection and purification technology should be executed according to the construction plan as outlined in Table 3.
Table 3: Construction Plan for Dynamic Disinfection Purification
Item No. Scenario Construction Method Equipment Requirements Engineering Requirements
1 Building Indoor Spaces Disinfection & Purification Dual-state ion disinfection and purification equipment and core components 1. The selection of the equipment should match the volume of the indoor space, with a nominal applicable volume not less than the space's volume.
2. When the indoor space is too large to be matched by a single piece of equipment, increase the quantity of the equipment, ensuring that the total nominal applicable volume is no less than the space’s volume.
3. For indoor spaces using multiple pieces of equipment, plan the installation points reasonably so that the airflow from each device evenly distributes throughout the entire indoor space.
4. Prioritize selecting core components integrated with the air outlet if there are existing air conditioning or ventilation system facilities in the indoor space.

2 Transportation Spaces Disinfection & Purification Dual-state ion disinfection and purification equipment, core components, and vehicle-specific ion disinfection and purification equipment 1. For vehicle spaces up to 7 seats, select a specific vehicle-mounted ion disinfection and purification device.
2. For vehicle spaces over 7 seats, the driving compartment should have a vehicle-mounted ion disinfection and purification device, while the rest of the space should be equipped with ceiling-mounted dual-state ion disinfection and purification devices; preferentially choose components integrated with air outlets if there are existing air conditioning or ventilation systems in the vehicle.
3. The total nominal applicable volume of all equipment used should not be less than the volume of the vehicle's space.
4. Plan the installation points reasonably so that the airflow from each device evenly distributes throughout the entire vehicle’s space.

6.3 Disinfection Factor Distribution Grading Requirements
The distribution requirements for dual-state antibacterial epidemic prevention and control disinfection factors are listed in Table 4.
Table 4: Disinfection Factor Distribution Grading
Grade A A+ A++
Distribution Index Static coating and film surfaces within the space Surfaces closely and less closely related to the environment Surfaces closely, less closely, and unrelated to the environment
Dynamic low-temperature ions Full distribution in the space Full distribution in the space Full distribution in the space
