Heatpack - an application for designing heating systems and technological heating for ventilation. Piping in Heatpack is drawn by tracing out the installation point by point after having selected technology, size (diameter) and elevation settings. Heatpack automatically inserts piping elements such as elbows, reducers, tees and crosses using the default libraries. The program features "open" libraries of pipes and heating media, so that the user may easily specify custom parameters for each technology, which can then be saved to file. Boilers, radiators, pumps etc. are inserted from libraries into the drawing as AutoCAD blocks. Based on the heating power specified for radiators and on the temperatures given for the heating medium in the supply and return pipelines, the program performs flow quantity calculations. As all information is available regarding flow quantity and geometry of the installation, the software performs the required hydraulic calculations, pipe sizing and determines the appropriate adjustments for balancing valves and calculates the authority of regulating valves. Heatpack allows the user to determine drawing scale, default parameters of element libraries, as well as the graphic properties of elements, numbering and information tables. All defined settings are saved in a user profile that can be reused in later projects. Heatpack can also create development views of the entire installation dynamically based on the floor plan view(s). The installation may be represented in full geometry or in schematic view, where piping is shown by single lines. The list of elements as well as the pressure drop report may easily be exported to an MS Excel worksheet or to .txt file for convenient printing.
Available for everybody
Hard to believe? But how better to describe CAD software that automates the process of drawing heating systems, provides available open and very detailed libraries of equipment, accessories, piping and heating mediums, performs pressure loss analysis, automatically creates specification of the designed installation, gives detailed reports of pressure conditions, and its price is only 225 EUR (for full AutoCAD version)?
The simplicity of 2D with advantages of 3D
Yes, it is possible. Even though Heatpack operates in 2D, some of its functionality is extended to 3D. Heatpack does have considerable 3D drafting functionality as it keeps track of the elevation for each element. While placing stand-alone elements (boilers, radiators etc.), the user must specify the distance to the floor. For the piping elements that follow, the program assigns elevation automatically. Thus, the program is able to make cross sections and system schemes (plane, one-line representation developments of the installation). Modifications made in the cross section view of the installation is updated in the plane view drawing. The result is that drawing files are kept relatively small, so standard hardware available in practically every design office is sufficient to run the program. Designing is simplified so much, that a person having just basic knowledge of AutoCAD needs only 2 to 4 hours to start working with the program – yet another reason to select Heatpack. The Heatpack Help leads the user through each designing step and helps become familiar with all commands. It is available from each dialog box: pressing the “Help” button will open it on the page describing the active window.
Equipment libraries without limitations
It is true – with Heatpack, you can draw any element required for your installation owing to the unusually rich general libraries (without determining manufacturer). All piping technologies are displayed in tables where the user may modify pipe parameters and then save them to a *.tsv file that can be used in later projects.
If you cannot find a specific element that you require, you can still define this element as a “nonstandard element”, with the full functionality of regular elements selected from the libraries. When executing a working project, you have another possibility - libraries
of manufacturers, where each element has predefined type, name and range of
sizes, accessories etc.. The program also stores precise geometry for these
elements, inserted into the drawing as AutoCAD blocks, thus significantly
accelerating the speed of drawing. Main installation units are joined by piping
drawn in a way similar to AutoCAD polylines, only with adjustable elevation,
technology and diameter settings. Heatpack automatically inserts piping
elements such as elbows, reducers, tees and crosses, displaying the proper
pipeline geometry.
New dimension to manufacturers CAD libraries
Heatpack enables manufacturers of equipment and accessories to provide designers access to their own element libraries, having unlimited possibilities for description details: all options, accessories, dimensional range and hydraulic characteristics can be specified. This means real CAD designing without the use of any “paper” catalogue sheets or searching through CD-ROMs. Heatpack guarantees complete service for every manufacturer, enabling automatic updating of their libraries for users of the program.
Heatpack makes the material specification instead of you
No more messy numbering, dimensioning and preparing material specifications! Heatpack performs these operations automatically in no time, so you can concentrate on solving engineering issues. You should also not be afraid to make changes in basic design even during the stage of generating documentation, because all material specifications are updated dynamically, changes made on the drawing are always reflected in the generated documentation. The “List of elements” is displayed in a table that may be easily exported to an *.xls or *.txt file.
Pressure loss analysis
Heatpack calculates medium flows based on the plane view drawing of the installation, on which the following parameters are specified: heating power of radiators, the temperature of heating medium in both the supply and return pipelines and the medium type. All input data is provided through the specified power values and by the drawn geometry of the installation. Program performs automatic pipe sizing (selection of pipe diameter) based on maximal speed or maximal linear pressure drop. Heatpack calculates pressure drop values and automatically determines the appropriate adjustments for balancing valves. When placing control valves, Heatpack selects the first available Kvs setting that results in the closest possible match to the valve authority desired by the designer. Finally, the program verifies each system, checking piping connections and ensuring proper implementation of the selected hydraulic regulation solution. Having finished designing the installation, you will receive the required pump head as well as the flow and pressure drop values in each branch. The program will also compile a report based on the pressure loss calculations that can be exported to *.xls or *.txt file and attached to the documentation.
