The spray pump should be interlocked with the supply fan. 喷水泵应与送风箱相联锁。
For example, switching logic can be defined to have the return fan start after a programmed delay from the time that the supply fan was started. 比如一个切换逻辑可以用来定义一个风机的开起,当程序定时过后,风机起动。
The proportional-integral ( PI ) control method with weak proportional action is recommended for the supply fan of such a residential VAV air conditioning system, in order to keep system control stability and designed indoor temperature. 认为在小型家用VAV空调系统中,应当采用具有较弱比例控制作用的PI控制方法对送风机(SF)进行控制,以保证系统整体控制的稳定性,实现室温控制效果。
Comparatively studies two control methods for the supply fan, using the dynamic model for a residential VAV system with two conditioned spaces. 以具有两个独立控制区域的小型家用VAV空调系统为对象,利用所建立的系统仿真模型,对两种不同的送风机(SF)控制方法进行比较研究。
The successful application of the control method requires proper matching between zone cooling loads and flow capacities of the supply fan and the VAV boxes, and adequate ductwork design. 为保证变静压控制VAV系统运行良好,要求风机容量与负荷恰当匹配,同时要求风管的布置和形式设计合理。
