at a Künette trench width of 80cm, Künette length per circuit 20cm.
2)
Pressure loss in brine collector (incl. distributor), but without connecting pipework, based on Ethylene Glycol 25%.
3)
Volume of brine collector (incl. distributor and evaporator), but without connecting pipework,
The amount of anti-freeze is 25-30% of the sum of the volume of brine collector + connecting pipework.
