Detail on Technical Data for Heat- and Chill Generators
Information on the technical data dialog for heat- and chill generators.
You are here:
Name
Specifies the name of the component. You can modify the name. Clicking 
restores the default setting.
System name
For the sake of better differentiation when there are several systems, you may enter a name. This name will be displayed in the calculation dialog when selecting a system. When printing, the systems will be available for selection. The data will be automatically transferred to the remaining heat or cooling generators.
Supply water temperature, Return water temperature
In the heat- or chill generator, specify the supply- and return water temperature for the entire pipe network. If multiple boiler systems are concerned, the data will be automatically transferred to the remaining heat generators. Changing temperatures is only possible after having detected the pipe network.
Portion of generator
Changing temperatures is only possible if multiple boilers are installed. If only one heat generator is installed, the value is automatically set to 100 % and is deactivated.
For multiple boiler systems, enter here the portion of the mass flow rates which is supposed to be covered by the individual heat or chill generator. At first, the default value of the portion is 100 %. You may split the portion of the mass flow rates so that the sum of all heat generators is 100 %. Likewise, redundant generators with a portion of 100 % each are possible. Moreover, mixed forms are possible: A part of the generators sums up to 100 %, to which one or several redundant generators with 100 % each are added. The sum of the mass flow rates of all generators ought to be 100% or a multiple thereof, else, a notification will be displayed in the report.
Water volume
Enter the water volume of the heat or cooling generator here. This value will be used for the calculation of the system volume and for the dimensioning of the diaphragm expansion tank. If the water volume has not been specified, a report will be issued during calculation. This only occurs with a diaphragm expansion tank installed.
Zeta value, Pressure loss
Enter either a fixed zeta value or a fixed, absolute pressure loss in Pa.
contains pump, calculate
contains pump
Activated: In the calculation, the presence of a pump is simulated for the pipe network. You can determine the capacity of the pump by activating the calculate checkbox during the calculation, or you can set the pump pressure manually. Manually entered values are displayed in bold. Clicking 
resets manually entered values to value determined in the calculation.
Deactivated: In the calculation, no pump is simulated for the pipe network and the installation of a separate pump is required. If no pump is installed, during calculation an error message appears in the Reports and the network cannot be calculated.
Medium
Opens the dialog System-related medium which allows for editing of the medium currently used by the system. The globally defined medium is usually used.
