A Study on the State of Air motion and It`s velocity distribution Indoor by the Models testing |
| Abstract |
Natural Ventilation must be have high Velocity and much quantity of indoor change air in the case of being hot and humid like the climate in our country in summer.The velocity of indoor air stream can be decided by the combination of before and behind window sizes at constant out door air velocity, And the average velocity or change of air quantity indoor are decided by combination and sizes of various windows. Therefore in this study, several types of model have been tested for those purpose.And the findings are as fellows(1)There is a large gap in average indoor air stream velocity according to open area ratio in spite of same gross open square per wall square. That is it can be say that m>1 is much more than at m<1 for average velocity of indoor air stream.(2)The higher "m" is the higher the velocity of inflow opening, But when m=2.0, the range of increase stops. |
