Underground Chilled Water Piping
Underground Chilled Water Piping
(OP)
Guys,
Does anyone have experience with underground piping for a cloed-loop chilled water system for a residential house? I plan on using a 3" PVC supply line to the house (500 ft to the house)....some questions pop into my mind like..
1.) How do you penetrate to the ground? Bracing or Support needed?
2.) Should I use expansion joints underneath the ground? Sensors at each joint? Tied into a DDC system, or stand-alone?
If anyone has some input into this, or knows where to go for some design info, It would be greatly appreciated.
Thanks

It will be cheaper and easier, although less attractive, to run the pipe above ground. Put it on standoffs, insulate it, and wrap it with reflective aluminum. I assume you are using a water/glycol solution so you can avoid putting heat tape on the pipe
For that length of pipe you may want to consider expansion joints, but check with the codes and standards for requirements/type/spacing/etc.
Pump sizing and pressure drop are a concern. Make sure everything is compatible.
