Design Instructions for Airborne Smallpox in the Cleansing Surgery

Ventilation smallpox: design instructions for a clean operating room

In the design process of the clean room, the amount of air sent is generally determined by the number of air exchange times. For the first-level operating room, the requirements are strict. For clean one-way flow, it is generally not determined by the number of air exchange times. Its air supply is: 2.6 × 2.4 × 0.45 × 3600(wind outlet specification is 2.6 × 2.4, wind speed is generally 0.2 m/s ~ 0.3 m/s, considering attenuation, generally take 0.4 m/s ~ 0.45 m/s[ 1] The air outlet of the operating room is generally used for wind ceiling). Secondary operating room: 30 to 36 / H,[ 2] Level 3 operating room: 18 to 22 / H, Level 4 operating room: 12 to 15 / H.

Taking a hospital clean operating room summer once wind system as an example, the design parameters are as follows:
