Details on Optimization

Information about the Optimization section.

The Optimization section is a view created specifically to improve the design. It replaces or complements the Optimize button at the project, building part, storey and apartment level. In the room view you can still perform the optimization using the Optimize button in the toolbar.

Note:

Optimizations of the layout should definitely be made before the circuits are drawn.

You are here:

Module overview ➤ Panel heating/Panel cooling ➤ Building structure ➤ Project level/Building element level/Floor level/Apartment level ➤ Optimization

Supply water temperature

Defines the temperature of the supply water in °C.

Optimizing functions for marked lines

Displays the automatic functions to improve the design of the rooms.

Laying spacings

Optimizes the laying spacing of the marked lines in the Edit mutually column. A differential temperature optimizing is performed during a laying spacing optimization.

Number of circuits

Optimizes the number of circuits in the marked lines in the Edit mutually column. An optimizing of the number of circuits equates to a redesign, as a laying spacing and differential temperature optimization takes place at the same time.

Room table

Lists the designed rooms of the selected level and displays their parameters.

Most parameters can be adjusted directly in the table. Critical points such as over/under capacity or excessive pressure loss are highlighted in color.

If several systems with different dimensioning locations (e.g. floor and wall systems) are used in one room, the systems are listed in separate lines. Border zones and occupied zones of circuits are also listed in separate lines.

Element

Description

Edit mutually

Determines which lines are optimized together.

Clicking the column headline Edit mutually activates or deactivates all rows.

Location

Displays the room name and the numbers of its location in the building structure.

For rooms with occupied and border zones, these are indicated by OZ and BZ.

tRoom °C

Determines the target room temperature.

Both values as well as variables can be entered.

A double click into the field or the button opens the dialog Temperatures, where other temperature variables can be selected and new temperature variables can be created.

R Surface m²K/W

Determines the thermal resistance (R-value) of the surface.

A double click into the field or the button opens the dialog R-Values, where other variables for the R-Value of the surface can be selected and new variables can be created.

System

Defines the system used. The abbreviation of the System preselection is used.

A Double click into the field or the button opens the Select a system element dialog, where another system can be selected out of the system preselection.

LS cm

Defines the laying distance of the pipes.

A double click in the field or the button opens a drop-down list with the system-dependent laying distances.

Diff. temp. K

Defines the differential temperature between supply and return water.

Phi int. W/m²

Displays the capacity actually released.

Phi int. %

Displays the capacity coverage of the room in percent. The value is calculated from the capacity required for the internal room temperature and the capacity actually provided.

Surface temp. °C

Displays the temperature of the surface.

Qty circuits

Displays the quantity of circuits in the room.

Circuitlgth. m

Shows the total circuit pipe length, including the feed pipes.

max. dp mbar

Shows the circuit pressure loss with the worst pressure drop in the room. The value is formed from the pipeline pressure drop and the valve pressure drop in the open state. In circuits with flow rate controllers, the minimum working pressure is also taken into account.

Toolbar of the section Optimization

Room view

Switches to the room view of the room whose zone is selected in the table.
