Drawing pipes
In Hysopt there are three different pipe types for heating as well as for cooling.
...
Pipe parameters
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 is explained in the following chapter of this Wiki "Select pipes". Pipe length and pipe type are self-evident.
...
Thermal losses
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, and environment temperature.
...
Isolation thickness = 0,06 m
Zeta- value
In addition to the linear pressure drops in the straight pipe pieces, additional pressure drops occur in the tubing network as a result of the resistance to the flow of water during changes in flow direction and/or water velocity. This occurs mainly at:
...
Length surplus percentage
Instead of filling in all the ζ-values per pipe segment in Hysopt. The user can also choose to add a percentage extra pressure drop per pipe segment.
Depending on the tubing configuration of the installation, this percentage may vary from 10% to 40%, only when using steel pipes. With a normal configuration, a percentage of 20% can be held. In the case of an installation with many turns per meter, 30-40% can be held. When using a plastic tube, the percentage ranges from 50% to 70%, again depending on the tubing configuration
Selecting pipes in Hysopt
After the action "compute design flows" you go to the next step "Select pipes"
