I noticed that OpenStudio tends to add automatically some adiabatic pipes in the plant loops even if you didn't put any, including:
- A Supply outlet pipe
- A Demand inlet pipe
- A Demand bypass pipe
- A Demand outlet pipe
Why is it adding a bypass only to the demand and not the supply?
It seems that OpenStudio checks whether you have included the inlet/outlet pipes and doesn't add them if there are already there. But it seems that it will always add a demand pipe, even if you do have one. Why?
Should/can you manually create the pipes?
