The Analysis of Ventilation System Design and the Air Volume Balance Calculation of Hygiene Passing Through with the Combination of Normal Time with Epidemic Period in a Community
Taking the example of a community with combination of normal time with epidemic period in Zhengzhou,Henan Province,the main building function layout and ventilation system design requirements with epidemic conversion are introduced.According to the equation of air quantity balance,the influence of pressure difference between adjacent rooms in the hygiene passing through on air quantity was analyzed under the conditions that the door and window gap were 0.004m and the air change rate was 20h-1 in the first undressed room.When the pressure in the protective clothing dressing room is 5Pa,the pressure in the dressing room is 10Pa,the pressure in the second undressed room is-5Pa,the pressure in the first undressing room is-25Pa,the air quantity of each room is the minimum.The air change rate is 22.9h-1 in the dressing room,3.4h-1 in the protective clothing dressing room,6.9h-1 in the first undressing room,4.2h-1 in the first undressing room.
