The lower edge of the intake window for natural ventilation in summer should not be higher than ( ) m above the ground, so that air can flow directly toward the work area. The lower edge of the intake windows for natural ventilation in winter is generally not lower than ( ) m. If it is below ( ) m, effective measures should be taken to prevent cold wind from blowing towards the work area. A 1.0 B 2 C 1.2 D 4
For intake windows that utilize natural ventilation in summer, the lower edge of these windows should not be higher than (C) m above the ground level, so that air can flow directly toward the work area. The lower edge of the intake window for natural ventilation in winter is generally not lower than (D) m. If it is below (D) m, effective measures should be taken to prevent cold wind from blowing towards the work area. A 1.0 B 2 C 1.2 D 4

For intake windows with natural ventilation in summer, the lower edge of these windows should not be higher than (1.2) m above the ground level, so that air can flow directly toward the work area. The lower edge of the intake windows for natural ventilation in winter is generally not lower than (2) m. If it is below (2) m, effective measures should be taken to prevent cold wind from blowing toward the work area.

For intake windows with natural ventilation in summer, the lower edge should not be higher than 1.2 m above the ground level, so that air can flow directly toward the work area. The lower edge of the intake windows for natural ventilation in winter is generally not less than 4 meters. If it is below 4m, effective measures should be taken to prevent cold wind from blowing toward the work area.
For the intake windows used for natural ventilation in summer, the lower edge of these windows should not be higher than (C 1.2) m above the ground, so that air can flow directly toward the work area. The lower edge of the intake window for natural ventilation in winter is generally not lower than (D 4) m. If it is below (D 4) m, effective measures should be taken to prevent cold wind from blowing toward the work area.
