Drawing pipes
In Hysopt there are three different pipe types in heating as well as cooling. The selection of the diameter of the pipes diameter is explained in the following chapter "Select pipes".

Pipe parameters
Following The following figure shows the parameter list on a pipe segment in Hysopt. Every pipe type has the same list of parameters.
The selection of the diameter of the pipes diameter is explained in the following chapter of this Wiki "Select pipes". Pipe length and pipe type are self-evident.

The thermal losses can also be added to the pipes. If you click on the pencil on the right in the main parameter list, the pop-up shown below will appear. The classes that can be selected are based on the German standard DIN EN 12828.
The isolation value changes depending on the pipe diameter, this is shown in the table below for class 1 to class 6. The thermal losses will be calculated during a dynamic simulation in the function of the pipe length, pipe diameter, isolation class en and the environment temperature.
