Technical Data for Fresh Water Stations
Information about the technical data dialog for fresh water stations.
Fresh water statinos and heat interface units are considered in pipe network calculation by LINEAR Analyse Heating and LINEAR Analyse Potable Water and are correctly laid out for dimensioning of the pipes. They are on parts lists with all necessary and optional accessories.
The heat interface unit provides an individual apartment with heat and hot water. In the heat station, heat is transferred directly from the heat generator to the apartment via the heating supply. Potable water is heated using a heat exchanger in the heating supply water. This way, circulating pipe from the central heat generator to the apartment can be spared. As the pipes from the heat interface unit to the potable water taps are short, no measures are required to combat legionella and there is no need to take samples.
You can find neutral fresh water stations and manufacturer specific heat interface units in the scheme generator. All symbols in the assistant for fresh water stations and heat interface units are manufacturer specific, all symbols from the toolbar are neutral.
In the potable water pipe network calculation, the heat interface unit is connected using at least one cold water inlet and one hot water outlet. The cold water outlet can branch off ahead of the heat interface unit and directly lead to tapping points in the apartment.
Optionally, a circulating pipe can be connected. Separate symbols exist for that purpose. If circulating pipe is not connected, the section Circulation in the technical data dialog remains deactivated.
You are here:
Name
Specifies the name of the component. You can modify the name. Clicking 
restores the default setting.
Settings
Hot water temperature: Hot water temperature is initially suggested to be 60 °C. You may enter a different temperature for each heat interface unit. Clicking on 
will reset the temperature to its preset value.
Pressure loss PWC outlet (heat exchanger): Enter the heat exchanger-caused pressure loss for the hot water outlet. Alternatively, you may enter the cv-value along with the opening pressure loss (20 – 100 mbar).
Pressure loss PWC inlet (water meter): Enter the water meter-caused pressure loss for the cold water inlet. If in your project the water meter is a separate symbol, enter zero in this field.
Alternatively, you may enter the cv-value along with the opening pressure loss (20 – 100 mbar).
Circulation
Name circulation system: At each heat interface unit with a circulation connection, an individual circulation system is created. Enter a name for a better distinction.
Pressure loss/cv-value: Enter either the pressure loss as relating to the volume flow rate, or the Cv value.
Pump included in device: Even if the heat interface unit contains a pump, its use must first be activated. If a circulating pump is built into the heat interface unit and should be considered for calculation, activate the option Pump Included in Device.
Delivery height: Initially, a neutral pump is used and the delivery height calculated. If you know which pump you will be using, deactivate the option Calculate and enter the delivery height.
Pump: For some manufacturer components, a manufacturer pump can be selected using this button.
