Pre-define global settings for all neutral fresh water stations in the project.
You are here:
Requirement Potable Water
Enter the capacity data for the station in this section.Temperature (cold): Sets the cold water temperature for the apartment. The cold water temperature is the basis for the determined capacity data of the heat exchanger within the station.
Temperature (hot): Sets the hot water temperature for the apartment.
Tap Rate: The peak demand of the 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 multisupplier fresh water stations.
Technical Data
Supply Water Temperature: The supply temperature for potable water heating. The supply water temperature may not be higher than the supply water temperature in the heat generator. It should not exceed 65° C, as this can lead to calcification in the heat exchangers.
Return Water Temperature: The Return water temperature for potable water heating. Return water temperature in a station is lower than return water temperature in the heat generator due to additionally being reduced by heating potable water.
Differential Pressure Closed-Loop Controller: The pressure loss of the differential pressure controller which is included in the heat interface unit component. If the differential pressure closed-loop controller is installed externally, set the value to zero here and enter the pressure loss in the technical data of the differential pressure closed-loop controller.
Pressure Loss, Kv-Value: Manually entered pressure loss or Kv value of the heat interface unit.
Volume: The water volume of the heat interface unit is required to calculate the system volume and to design the diaphragm expansion vessel (DEV). If no water volume is entered, a note will be issued in the dialog Edit Reports.
