體(ti)系方法通常有分(fen)層設(she)置水平式新風體(ti)系和垂直式新風體(ti)系。

（1）分層設置水平式新風(feng)(feng)(feng)(feng)體系(xi)新風(feng)(feng)(feng)(feng)體系(xi)按樓層分別設置。新風(feng)(feng)(feng)(feng)吸(xi)入方法有兩種(zhong)，一(yi)種(zhong)是新風(feng)(feng)(feng)(feng)通過從(cong)外墻(qiang)上開洞從(cong)室外吸(xi)取(qu)(qu)；另(ling)一(yi)種(zhong)是設一(yi)總新風(feng)(feng)(feng)(feng)豎(shu)風(feng)(feng)(feng)(feng)道，防排(pai)煙(yan)系(xi)統，各層新風(feng)(feng)(feng)(feng)機組(zu)從(cong)豎(shu)風(feng)(feng)(feng)(feng)道取(qu)(qu)風(feng)(feng)(feng)(feng)。

前一種取新(xin)風(feng)方法，機房排煙系統，不需在新(xin)風(feng)機組入(ru)口(kou)處設(she)防火(huo)閥，后(hou)者會集取新(xin)風(feng)，關于高層建筑，總新(xin)風(feng)豎風(feng)道要跨過防火(huo)分區，每層新(xin)風(feng)機組的吸入(ru)口(kou)風(feng)管(guan)上應設(she)70℃熔斷的防火(huo)閥。

（2）垂(chui)直式(shi)新(xin)風(feng)(feng)體系垂(chui)直式(shi)新(xin)風(feng)(feng)體系是(shi)室外空氣經過新(xin)風(feng)(feng)機組(zu)處理(li)后，淮南(nan)排煙(yan)系統，通過豎風(feng)(feng)道送至空調房間(jian)，一(yi)般新(xin)風(feng)(feng)機組(zu)設在(zai)房頂(ding)。
