How big is the
opening window?
1 too small
The result is poor ventilation, neither energy saving nor
livability; the problem of too small window opening is relatively easy to
solve, and various design codes have stipulated the minimum value of the ventilation
opening area of the house.
In a bedroom about 12 square meters, a 600mm × 1000mm opening can
meet the ventilation requirements; in a living room of about 20 square meters,
two 600mm × 1000mm opening can meet; a 4 square meter bathroom has a A 600mm
× 600mm opening is sufficient; a kitchen with a higher ventilation
requirement, a kitchen of about 5-6 square meters can have a 600mm × 1000mm
opening .
2 too big
The result is inconvenience to open, and even the inconvenience of
opening may affect the operation safety when opening and closing the window.
The opening fan of casement window: the width should not be greater than 700,
less than 500, and should be about 600; the height should not be greater than
1400, less than 900, and should be 1000-1200; using an oversized opening fan
(too wide or too high), especially outside When opening, you must carefully
consider the convenience and safety of opening.
When we pay attention to the problem of too large windows, we often only pay
attention to the width, but the height is also "lethal". For general
casement windows, when the height of the window sill is constant, the higher
the window sash, the higher the position of the opening handle, and during the
window opening action of "extended arms → leaning over", human hands
can The height reached is a downward trend.
Therefore, the sash is too high and the handle is too high, which will increase
the inconvenience of operation. For ordinary people with a height of 1.6 to
1.7m, the height of the flat extension of the arm is about 1.4 to 1.5m.
Considering the height of a common window sill of 0.9m, 1.0 to 1.2m is a
reasonable height for opening .
