| 摘 要： | 全空气集中空调系统必须借助风量调节阀来调节和平衡末端送风口的风量。风量调节阀系阻性部件,存在较大的压头损失,须消耗大量送风能量。如果降低空调机组出口压头,同时利用管道风机进行局部增压来保持远端风口必要的送风压头,无疑会降低风量调节阀的节流阻力损失,并可有效地降低空调机组的风机功率和能耗。

| Abstract: | The airflow of the terminal discharge air outlet must be adjusted and balanced by air flow adjusting valve in all air district air-conditioning system. The valve is an impeding part with larger pressure head loss and a lot of discharge energy consumed. If the pressure head at the outlet of the unit is reduced and partial pressurization is applied by duct air blower to keep the necessary pressure head at the remote outlet, thus the throttle resistance of airflow adjusting valve will be reduced and the power and energy consumption of blower of the unitpartial pressurization district air-conditioning energy consumption of discharge air adjusting valve forairflow duct blower. |
