RH & PRECISION CONTROL

 

Posted on: July 23rd, 2013 by mok

We designed and implemented precise air-cond system at 20 +/- 0.1 degree C for Upeca in Puchong who manufactures/machines metalic aircraft components to the precision of microns.  Room temperature variation exceeding 0.1 degree C will affect the precision of their products simply by virtue of metal expansion/contraction. Using PID controller alone is not sufficient, for such a small room and using DX system instead of chilled water system and at such low temp of 20 degrees C. Had to make sure that the compressor will never cycle off like normal a/c applications and ultimately able to deliver the cool air throughout the room such as to achieve +/- 0.1 degrees C for the entire room. As for RH control we have done 20 degree C @ 15% RH for Kotra Pharma in Melaka which they had failled so many times before.  Precision engineering will  no major air balancing if the ducts are sized accurately.
