I am not aware of any. It seems like it is really a matter of how cold the
conditions are. If you had a sprinkler system of uprights where the uprights
are the only piping dead ends then you might expect the water density
difference between cold at sprinkler and warm at the circulating piping to
Think how much pipe surface you would have to transfer heat, and the volume of
the protected space

Wouldn't there also be an energy cost to a circulating system? Every piece of
pipe will pass heat to the refrigerated space. There is a cost to that. Then
the refrigeration system needs to run to remove that heat and blow it off to
the atmosphere. Or are you intending on intercepting some of tha
NFPA 13, 2010 22.1.5, Working Plans for Automatic Sprinkler Systems with
Non-Fire Protection Connections, may be of help. Granted the appendix shows
heaters being connected to the sprinkler system with 286 degree sprinklers, but
this may of some assistance.

What about thermal transfer to temperature sensitive sprinkler heads? Not a
very good idea, without sophisticated sensors and controls.

Also, heat tracing is not approved for protecting an entire system. That is
not it's intent.
You didn't state what type of building or area is being protected. Is it
commercial, industrial or residential?
What are the conditions and why is the building/area not heated to prevent
