Exemplary Workflow for Cooling Design with AutoCAD

Step 1: 2D Design and Scheme Design

With the liNear toolbars, scheme generators, routing commands, connection functions for rigid and flexible pipes, automatic legends, slot design assistants and much more, you can draw calculable cooling systems independently of whether in schemes, isometric views or floor plans. The construction serves as the basis for the pipe network calculation. You also receive the functions for creating the architecture based on a drawing of the architect in any format. We provide you with a user interface that optimally supports you in every step of the design process!

Step 2: Cooling Load Calculation

To determine the cooling load of a building, a physical model of the building must be detected in a structured manner. liNear Building Analysis performs this analysis automatically on the basis of the CAD model. The cooling load is then calculated. If you have already calculated the heat load, you can of course use the building model detected for it. Both the German method according to VDI 2078 and the international method according to ASHRAE are available for the dynamic calculation. After defining design temperatures, shading and usage profiles, the program displays the results for the entire project, individual building parts, levels and for all rooms. 

Step 3: Dimensioning

After determining the cooling load, use the liNear dimensioning for cooling systems to cover the demand. This dimensioning is available for convectors and panel cooling systems. From extensive manufacturer libraries you can select your products already before the dimensioning is made. You can choose between a quick or a detailed dimensioning. With one click, dimensioned components are transferred to the model. Cooling convectors are automatically inserted and the panel cooling is drawn. Adjustments can be made in the model or in the dimensioning process and all changes are transferred bidirectionally.

Step 4: Pipe Network Calculation

With the graphically supported liNear cooling pipe network calculation, perfectly dimensioned and hydraulically balanced cooling systems are possible in almost all imaginable variants. Both the pipe run scheme and the 2D or 3D floor plan drawing can serve as the basis for the calculation. There is a great difference in the requirements of a cold pipe network calculation compared to those of a heating pipe network calculation. In particular, the testing of the use of approved materials and the media data for refrigeration are directly usable advantages. If there are still possibilities for optimization, the program informs you so that you can implement them immediately. Finally, the network is redimensioned. With fixed pipe dimensions, you can also calculate existing systems and optimize or extend the network. 

Step 5: 3D Design

This is pipe design that leaves nothing to be desired featuring an easy-to-learn operating concept that makes a difference. Build your three-dimensional and realistic systems in no time. You may switch on real-time checking, which prevents already during construction pipes and components from contacting each other. You can either design directly in 3D or automatically create a 3D pipe network using the calculated single-line pipe network following the pipe network calculation. The correct fittings and joining pieces are selected automatically during construction via the liNear Material Manager. Easily replace 2D symbols with 3D valves from manufacturer component catalogs and get a complete 3D model. Of course the model remains calculable in every design stage. It is also possible to recalculate the model after changes at any time. 

Step 6: Labeling and Transfer of Results

Write the results of your design work directly into the model. With the automatic labels, you will do this in a quick and easy way. You can define and reuse labels globally, per component group or for individual elements. It is also possible to add your own parameters, which can be included in the labels. All results such as bill of quantities, pipe network calculation, cooling load results or hydraulic balancing are output in various formats. All information is saved directly in the model. The final MEP model can optionally be provided for the BIM process via an IFC interface.
