　　7.2.2 人員(yuan)經常生活(huo)、休息、工作活(huo)動(dong)的(de)(de)空間（如(ru)居室、廚(chu)房、兒童活(huo)動(dong)室、中小(xiao)學(xue)生教室、學(xue)生公寓宿舍、育嬰室、養老院、病房等）應采用直接自然通風。本條中規定的(de)(de)通風口面積的(de)(de)限值保持了(le)原(yuan)《通則》的(de)(de)規定。進出風開口的(de)(de)有(you)效面積應進行(xing)計算(suan)，計算(suan)時將(jiang)開啟扇開到通風位置，然后計算(suan)有(you)效通風面積。

　　7.2.2 The spaces where personnel often live, rest, and work (such as living rooms, kitchens, children's activity rooms, primary and secondary school classrooms, student dormitories, nursing homes, nursing homes, wards, etc.) should adopt direct natural ventilation. The minimum limit of ventilation area specified in this article maintains the provisions of the original General Rules. The effective area of the inlet and outlet openings should be calculated by opening the fan to the maximum ventilation position and then calculating the effective ventilation area.

　　除了保(bao)證必(bi)需的通風(feng)開口面積(ji)，良好的通風(feng)效果還依賴(lai)是否(fou)有通風(feng)路(lu)徑。設計(ji)中應(ying)合理設置進出(chu)風(feng)口的平面位置、高度等，以(yi)利(li)于室內形成良好自然通風(feng)流場。設置在外墻上的懸開窗(chuang)(chuang)，其通風(feng)開口有效面積(ji)按下(xia)列要求確定(ding)：1 當開啟扇開啟角度大(da)于70°時，其面積(ji)可按窗(chuang)(chuang)的面積(ji)計(ji)算。

　　In addition to ensuring the necessary ventilation opening area, good ventilation effect also depends on whether there is a ventilation path. In the design, the plane position and height of the air inlet and outlet should be reasonably set to facilitate the formation of a good natural ventilation field indoors. The effective area of the ventilation opening of the suspended window set on the exterior wall shall be determined according to the following requirements: 1. When the opening angle of the opening fan is greater than 70 °, its area can be calculated based on the area of the window.

　　2 當開啟角度小于70°時，其面積可以按照下式計算(suan)：Fp=d×(h+B)式中：Fp-通風開口有效(xiao)面積（㎡）；d-開啟扇頂（或底邊）到其關(guan)閉位(wei)置的距(ju)離（m）；h-開啟洞(dong)口凈高（m）；B-開啟洞(dong)口的凈寬（m）。

　　When the opening angle is less than 70 °, its area can be calculated according to the following formula: Fp=d × (h+B), where Fp - effective area of ventilation opening (㎡); D - Distance from the top (or bottom) of the fan to its closed position (m); H-Net height of the opening (m); B - Clear width of the opening (m).

　　3 當(dang)采用推拉窗時，取(qu)開啟后的(de)通(tong)風洞口尺寸。廚房通(tong)往陽臺的(de)門，不計入廚房的(de)通(tong)風有效面積。

　　When using sliding windows, take the maximum ventilation opening size after opening. The door from the kitchen to the balcony is not included in the effective ventilation area of the kitchen.
