[FONT=&quot]There is the primary pump and loop, which circulates water through the chiller at a constant speed. Then there is the secondary loop to the building, which has it's own pump, and typically VFD. They share a common pipe, or decoupler pipe, which basically connects between the supply and return of these two loops. As the secondary loop pump increases speed and requires cold water, it will pull the cold water out of the primary loop. As it pulls more and more water out of the primary loop, the flow through the decoupler pipe is less and less. It will reach a point where the building return is equal to the primary pump GPM, and there will be no flow in the decoupler pipe. So in essence, there will be no circulation, but all return water going into the chiller. In fact, the decoupler pipe can actually flow backwards, depending on the GPM of each pump and the mixing of bulding return with chiller supply. معلش ما لقيت غير هادا الشرح بس بالانكليزي[/FONT]
