Heating pipe net calcuation

liNear Analyse Heating

Efficient calculation of heating pipe networks.

Today, perfectly dimensioned and hydraulically balanced heating systems are absolutely required in terms of energetic aspects. With the graphically based liNear heating pipe network calculation, two-pipe heating systems including Tichelmann pipe arrangement and connecting systems may be calculated separately. Within a system you may thus work with different temperatures. The basis for calculation may be either the pipe run scheme or the 2D or 3D floor plan drawing. Several control levels allow hydraulic balancing even of complex systems.

All Analyse modules run in combination with the liNear Desktop Heating and Autodesk Revit. 

Features

liNear CAD Browser with Revit

You can use the liNear CAD Browser in combination with AutoCAD, liNear CADinside and also with Autodesk Revit. Countless manufacturer parts to use in your planning process. Intuitive handling with a direct connection to your CAD program to integrate the parts into your net.

Calculating in all planning and display modes

The network can be calculated in scheme, floor planing or 3D isometric. You can choose the mode from project to project and decide which one is efficient and appropriate. The calculation always works the same way with reliable results.

VDI 3805 interface for valve data sets

Do your dimensioning with appropriate control valves and execute the hydraulic balancing with settings based on VDI 3805 datasets approved by the manufacturer.

Specify boundary conditions

Extensive settings in the boundary conditions for calculations (maximum speed / pipe friction pressure gradient, valve authorities, active pipe diameter, fixed pipe dimensions for existing installations, etc.) are making the software a perfect tool for every application.

Platform independence

With liNear Analyse you optionally work on the basis of drawings from Autodesk AutoCAD, REVIT or liNear CADinside. The functions of the pipe and air duct network calculations are identical throughout the CAD platforms. No familiarization is required in this respect.

Exact medium data

Exact media data are already contained. Includes the option to define medium tables on your own for instant Water-Glykol mixtures. Of course you can also define own mediums.

Hydraulic balancing

The hydraulic balancing can be done primarily via thermostatic valves, lockshield valves and the optimal combination of both. Gradual all necessary components can be added, such as regulating valves, differential pressure closed-loop controller, flow rate closed-loop controller, pumps, valves, and specified for example with the VDI 3805-2 and considered for hydraulic balancing. Hydraulic balancing is per plant and per pump section performed. Excessive pressures are throttled by differential pressure closed-loop controllers or pump. Several regulating valves in series are possible.

Manufacturer data libraries

With the large amount of original manufacturer data you can make the next step to a realistic planning with tested systems and components. This enables you to calculate with real product settings and as a result you receive a complete mass determination including article numbers. You can also calculate with neutral material.

Comprehensive visualization options

With the visual feedback of input values or calculation results, a quick-and-easy evaluation of a variety of data is possible. Dimensions, materials, but also velocities, pressure losses, and many more are visualized perfectly by the respective coloring of the network.

Calculation in all planning and display modes (scheme, 2D, 3D)

In each planning stage it is possible to have the drawn network calculated by the program. With already one pipe run scheme you can determine a working hydraulic system and detailed masses for your tendering very quickly. At the other end of the scale, calculating with a three-dimensional model ensures closest proximity to the actual implementation.

Recalculation of pre-dimensioned or existing systems

More and more existing systems are refurbished, reconstructed, or upgraded. To consider these systems according to reality, dimensions may easily be fixed in section parts or for the entire network.

Navigation in the pipe network system

The direct navigation in the pipe network system is one of the unbeatable advantages of the integrated graphical network calculation. Unfavorable flow paths or section parts are displayed directly in the model. Vice versa, you can use the option to simply select an object in the network in order to edit its calculation data.

Several networks or systems in one drawing

When comprehensive projects are concerned, a drawing often contains several systems. liNear Analyse can detect them and includes these in the selection options of the calculation dialog for printout – all in one work step.

Mass determination of single building sectors or apartements

The graphical net calculations allow you to select areas of the system for mass determination, e.g. Building sectors, storeys or apartments.

Complete parts lists

With the help of the large amount of manufacturer data sets for piping and ventilation systems including all necessary components it is doable without any additional effort to export a realistic parts list with all pipes, fittings, reducers and accessories. Perfect for an offer or tender.

Freely definable pipe and insulating tables

In case your requested pipe or insulating material is not available as a data set, it may be detected easily and quickly as manufacturer-neutral material.

Automatic and associative labeling

The calculation results are automatically integrated into the drawing and are updated with each modification of the calculation. Via freely configurable labeling blocks, you can control which calculation data in which planning phase are to be published with the drawing.

Working with drawing and calculation without interfaces

Integration into the CAD program and direct access to the CAD databases ensure the highest performance. At the same time, an interface between drawing and calculation is not required any longer. Problems with data exchange are now a thing of the past.

Detailed and standardized printouts

All calculation parameters and all results are documented comprehensibly and in detail in forms and lists – optionally in different languages.

Visualization of the results with liNear Data Coloring

Video - With the help of liNear Data Coloring you can display all results in an easy way. For example the heat loss, dimensions, materials, velocities, most unfavorable flow path, etc.

liNear Analyse for Revit

Video - You can also take advantage of the graphically-based pipe network calculations in combination with Autodesk Revit. As in AutoCAD and liNear CADinside the calculation is based directly on the drawing and naturaly accesses the CAD data.

Hydraulic circuits and separators

Video - To increase the accuracy of calculations, the range of hydraulic circuits and separators has been expanded. The hydraulic circuits replace the three-way valves on the symbol bar. Also heat exchangers and hydraulic separators can now be easily integrated and calculated directly in your construction.

Calculating multiple-boiler systems

Video - With liNear Analyse you can also calculate systems with several heating and cooling generators. Theses can be hydraulically integrated into the network and their valves and pipes are measured.
