Piping Work
Unit Resistance and PHE resistance by Glycol concentrate
The unit is composed of water pipes and PHE basically.
To ensure correct operation and predict the expected performance, Flow and Resistance table can be used.
And Flow and Resistance characteristic is dependent on on Glyco concentrate.

Changing Glycon concentration can cause the pressure drop of the system and it can leads to make flow rate rather slow.
Just in case performance degration, installer shall be careful of flow rate changes.
