摘要
对于常用风机的控制原理设计,设计人员习惯选用国家建筑标准设计图集10D303-2《常用风机控制电路图》,但对于两用单速风机及消防兼平时两用风机,当无DDC控制时,设计不应直接选用10D303-2图集的控制原理图。对此问题进行分析,并对《图集》控制原理图进行优化设计。
Designers used to select control schematic diagrams from Common Blower Fan Control Circuit Diagrams of National Building Standard Drawings （10D303- 2） for the control schematic design of general blower fans. While in designing dual-use single-speed blower fans and fire and general dual-use blower fans without DDC control, the control schematic diagrams of 10D302- 2 Standard Drawings should not be used directly. Aimed at this problem, the control schematic diagrams of 10D302-2 Standard Drawings are optimized.
