According to GB51039-2014 "Code for design of general hospital", for the return air grille in the HVAC system in the auxiliary room for isolation ward area, air filters with initial pressure drop less than 50 Pa, the one-pass penetration for microbes not larger than 10% and the one-pass arrestance for particles not larger than 5% should be installed. 4, the primary and secondary air supply outlets as shown in Fig. 7.3 should be chosen for the negative pressure isolation ward. The air return opening above the door of the buffer room can remove the pollutant from the airflow leaving the ward immediately, which is shown in Fig. 7 .8. For the ordinary negative pressure isolation ward, at least one buffer room should be set outside the ward based on the actual condition. Based on the data in Table 2 .4, For the ward where the door of the room is not air-tight, this flow rate of the exhaust air is equivalent to the pressure difference with value slightly more than 1 Pa indoors.	./cache/cord-015906-69srun8l.txt	./txt/cord-015906-69srun8l.txt
