Details on Global Presettings for Multisupplier Dwelling Stations
Information about the dialog for Global presettings for multisupplier dwelling stations in pipe network calculation for heating.
In the dialog Dwelling station use the function Global presettings to specify settings for all manufacturer neutral dwelling stations in your project. These data can be changed in the technical data dialog of individual dwelling stations.
You are here:
Temperature (cold)
Enter the cold water temperature for the associated apartment.
Temperature (hot)
Enter the hot water temperature for the associated apartment.
Tap rate
The tap rate determines the peak requirements of hot water demand. The standard value of 15 l/min corresponds to two consumers that are tapped simultaneously, a bathtub and a shower, e. g. Normal are around 12–17 l/min.
Heat capacity
The heat capacity is calculated and initially assigned to all manufacturer neutral dwelling stations in the model. These values can be edited in the technical data dialog of individual dwelling stations.
Supply water temperature
Enter the supply water temperature for heating potable water. The supply water temperature may not be higher than the supply water temperature in the heat generator. It should not exceed 65 °C in order to avoid calcification of the heat exchangers.
Return water temperature
Enter the return water temperature for heating potable water. Return water temperature in a dwelling station is lower than return water temperature in the heat generator due to additionally being reduced by heating potable water.
Differential pressure controllers
Usage of differential pressure closed-loop controllers is encouraged when using dwelling stations. If the differential pressure closed-loop controller is included with the dwelling station, enter the pressure loss of the differential pressure closed-loop controller here. If a separate component is used for the differential pressure closed-loop controller, enter a Zero here and enter the pressure loss in the technical data dialog of the differential pressure closed-loop controller.
Pressure loss, kv-value
Enter either the pressure loss or the Cv value of the dwelling station.
Volume
Water volume dwelling stations and will be used to calculate the system volume and for dimensioning the diaphragm type expansion tank. If no water volume is entered, a note will be issued in the dialog Edit reports. This only occurs with a diaphragm expansion tank installed.
