Technical Data for Expansion Vessel
Information about the technical data dialog for expansion vessels.
Using the dialog box for the Diaphragm expansion tank, you may select an expansion tank manually.
You are here:
Name
Specifies the name of the component. You can modify the name. Clicking 
restores the default setting.
Drag coefficient, Relief pressure, Determination of Expansion Volume
You may enter the Zeta value to be considered in the calculation. The relief pressure of the safety relief valve is taken from the safety relief valve´s component dialog and can only be changed there. The data for the determination of the expansion volume will be obtained from the pipe network (e.g. potable water heater).
Nominal volume Expansion vessel
Once the Nominal volume checkbox is activated, the expansion tank with the automatically determined minimum nominal volume will be used. If you wish to specify a particular nominal volume, set the option inactive and select an appropriate nominal volume from the drop-down list.
Subsequently, it will be displayed whether or not the nominal value is sufficient and which storage volume can be covered with this value.
