Determining Method of Ventilation Rate in Box Model Underground Parking Garages

SUN Jin-xu(Kaifeng Univerisity,Kaifeng 475004,Henan,China)  
Based on the mass balance law of ventilation in an all-round way and the box model for mass balance equation of indoor air pollutants,the emission of CO from automobiles in the underground garage can be calculated,and the dynamic formula for calculating the ventilation quantity is deduced in this paper.By calculation the method of point pollution source is used, in which the driveway is regarded as a line pollution source.By application in an actual project,the results show this method can better reflect the dynamic change of ventilation quantity in underground parking garage,compared with the usual methods.This indicates that this method and its structure are correct and can be used to calculate the ventilation quantity with the aim of energy-saving correctly and conveniently in practice.The experimental test and the theoretic analysis method in this paper are both simple,and can be applied in practice.
