Jason - Yeah there is several different arrangements of these systems, completely depends on the mall and region of the country. Yeah we call those 2 Pipe or 4 Pipe systems / 2 pipe is for 2 water pipes, 1 coil where the Mall heats water in winter and chills same water in summer 4 pipe is for 4 water pipes, 2 coils, 1 Coil for hot water and 1 Coil for chilled water
Excellent video as always. Would have liked to see how you triggered the freeze stat to check the economizer.None the less great video . Keep up your excellent videos.
Nice video thanks for the share! Up where I'm at it's not uncommon to see control valves on the supply side for chilled water. Hot water always on the return.
They make poly tube in clear? Many times I've ran into the situation where it would be so nice, if I could see what's inside this green or brown or puke poly tube that probably wasn't installed yesterday. 🤔 if only, everything was new.

A lot of our sites have either 2 hydronic coils or one coil with with a changeover valve for heating/ cooling with a face and bypass.
