離(li)心(xin)風(feng)(feng)機(ji)箱采用電(dian)機(ji)直(zhi)聯傳動(dong)，多風(feng)(feng)機(ji)結構（可同時(shi)向多方向的管(guan)道送(song)風(feng)(feng)），臥式為水平進出(chu)風(feng)(feng)，立式為水平進風(feng)(feng)垂(chui)直(zhi)上(shang)出(chu)風(feng)(feng)。

特點：運行平穩、噪聲低、體積小(xiao)、重量輕(qing)、外形美(mei)觀、維護保養方(fang)便 ;

應用(yong)：工(gong)業生(sheng)產、民用(yong)建筑、商(shang)業娛(yu)樂、文教衛生(sheng)等行業的空調工(gong)程系(xi)統的送風和排風,也可用(yong)于一般的送排風。

1. 風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)箱(xiang)選(xuan)用控制(zhi)參數為(wei)風(feng)(feng)(feng)量(liang)、全壓(ya)(ya)、效(xiao)(xiao)率、噪聲(sheng)以及電機(ji)(ji)(ji)(ji)功率等。有離心式(shi)和軸流式(shi)。2. 通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)由(you)于設置了風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)箱(xiang)，有利于消聲(sheng)。3. 通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)選(xuan)型時(shi)，應(ying)考慮(lv)管(guan)路系統的漏風(feng)(feng)(feng)損失(shi)、計(ji)算誤差，以及通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)實際風(feng)(feng)(feng)量(liang)、風(feng)(feng)(feng)壓(ya)(ya)的負(fu)偏差，一般采用風(feng)(feng)(feng)量(liang)為(wei)1.05～1.1，風(feng)(feng)(feng)壓(ya)(ya)為(wei)1.10～1.15 的安全系數。但也不采用過大(da)，以防(fang)止通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)長期處在低(di)效(xiao)(xiao)率區(qu)運行。4. 注意管(guan)網阻力特性(xing)與(yu)通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)特性(xing)的匹配關系。為(wei)使通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)能穩定運行，應(ying)使通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)在其效(xiao)(xiao)率點(dian)附近工作(zuo), 通(tong)(tong)(tong)(tong)(tong)(tong)風(feng)(feng)(feng)機(ji)(ji)(ji)(ji)的工作(zuo)點(dian)位(wei)于性(xing)能曲線中全壓(ya)(ya)峰值點(dian)的右側（即大(da)風(feng)(feng)(feng)量(liang)側，且一般位(wei)于全壓(ya)(ya)峰值的80%）。
