How is calculated the glycol volume and ratio in the software MyDualSun ?

 

Glycol is antifreeze used in the hydraulic circuit of a hybrid solar installation, it prevents freezing in the pipes.

The glycol content (in %) is calculated according to the location of the project in the world.

This gives for example in France :

 

Latitude <45°N

>45°N

-180→3°E

>45°N

3→6°E

>45°N

6→180°E 

Glycol percentage 40% 40% 45% 50%

 

In a more visual way, the separation is done according to this approximate delimitation:

 

 

  

Volume of Glycol for an installation

 

The volume of glycol mixture is calculated according to the following calculation:

 

Volume required (L) = PVT Name * 5 + Piping Volume + Link Volume (Portrait (0.27) or Landscape (0.45))
