1末端装置选择的一般原则变风量系统末端装置的正确选择与合理控制,对整个系统的运行能耗和房间的舒适性,有着十分显著的影响,一台容量偏大的末端装置,在运行时通过它产生的压力降可能较低,从而使空调机中送风机的能耗可以降低,但是,容量偏大的末端装置的最小送风量控制设定点都相对较高,这又会使送风机的运行能耗增加, A terminal device selection of the general principles VAV system end device the correct choice and reasonable control of the entire system of energy consumption and room comfort has a very significant impact, a larger capacity of the end device, at run time The pressure drop through it may be lower, so that the energy consumption of the blower in the air conditioner can be reduced, but the relatively small volume control set point of the blower with relatively large capacity is relatively high, Operational energy consumption increases,
