Chiller piping and Loops
Chiller piping and Loops
(OP)
Hi ,
i need to clarify some thing , i have a main chilled water supply and chilled water return pipe on roof top , this main pipe's are feeding 24 typical shafts .
i have 4 floors , when the risers reaches after distribution to last floor at the end ( since i have a Closed loop they are connected to each other )
now i have to provide a drain connection for the risers ( in case of maintenance ) i use a tee @ the center ( please Check the attachment ) and a ball valve and plus when the main pipe on roof top take's a branch for 1 shaft i have gate valves ,
please check the attachment for image and give me your valuable comments if this design is ok or i need to add more valves or i missed some thing
thanks

Add vents at the high point so you can drain down and vent out air when you refill.

I have to agree with Drazen and HVACMech, knowing how to best control your flow comes from experience and that is best coming from a senior engineer.
