1. Minimum new traffic for civil construction

room type	Minimum new traffic (m³/h·people)
Cinemas, theatres, gymnasiums, libraries, reading rooms, shops, museums, living rooms, classrooms	8.5
Offices, conference rooms, restaurants, doctor's offices, general wards	17
intensive care unit, operating room	30
Premium hotel room	30

1) For high-end hotel rooms, when the exhaust volume of the bathroom is greater than the value listed on this table, the fresh air volume should be calculated based on the exhaust volume, and the ventilation frequency of the bathroom should be calculated as 5-8 times/h.

2) Smoking is generally prohibited in public buildings and public rooms; a small amount of smoking is allowed in luxury hotel rooms.

2. Ventilation frequency in primary and secondary schools

room type	Ventilation frequency (time/hour)
primary school classroom	2.5
Junior high school classroom	4
high school classroom	6
Chemistry laboratory	10
toilet bathroom room	10
Gym	10
health room	2
student accommodation	2.5

The ventilation frequency for each type of classroom is calculated based on the required ventilation per hour specified by most school environmental health regulations.

The prescribed ventilation rates (m³/h·person) are: for primary school students - 9, for junior high school students - 14.4, for high school students - 21.6.

3. Central heating in cold and severe cold areas

room type	Ventilation frequency (time/hour)
classroom	1〜1.5

bathroom	5
Gym	3
health room	1

4. Ventilation frequency in nurseries and kindergartens

5. theaters and cinemas

The minimum fresh air volume in the auditorium can be selected as 7-10m³/(H·person). When the content of Co_{2 in the outdoor air is low, the lower limit can be used, and when the content is higher, the upper limit can be used [permissible concentration of CO}2Indoors, the steady state should be less than 0.0025m³/m³, and the amount of CO should be less than ₂Human emission calculation is 0.02m³/(h·person)].

When used as a meeting place for long-term use, it should not be less than 10m³/(h·Person); if it is used for general cultural activities and intermittently, it can be 7m³/(H·Person).

Select the exhaust volume of the movie projector according to the following values: (The ventilation frequency of the projection room should not be less than 15 times/hour)

700m³/(H unit) (arc lamp)

600m³/(H·3kW) (xenon lamp)

800m³/(H·5kW) (Xenon lamp)
