PROBLEM TO BE SOLVED: To calculate ventilation frequency and a necessary window area further readily at a degree of precision that is satisfactory for practical use.SOLUTION: Ventilation frequency V per unit time is calculated from a ratio R of a window area W to a floor area F of a living room on a certain floor of a building. A correlation equation between the ratio R and the ventilation frequency V is preliminarily obtained by statistical processing, and ventilation frequency V is calculated based on the correlation equation.SELECTED DRAWING: Figure 3 |
