This document provides an overview and details of the KLIMA Software package. The KLIMA Software consists of 13 interconnected modules for designing HVAC, water supply, fire fighting, and drainage systems for buildings. The modules allow for calculating thermal loads, selecting heating/cooling devices, and dimensioning ducts and pipe networks. Key features include automatic transfers of data between modules, interactive data entry through menus and Excel sheets, and output of results, drawings, and bills of quantities. The software is intended to provide a full HVAC design with minimum input data. Support and potential language translations are available from the developers.

MODULE 7 - Pipe Network Drawings Automatic generation and presentation in AutoCAD of Horizontal Pipe network and Pipe risers including Heating bodies and all required relevant textual data which were already defined in Modules 3A and 4. General characteristics of Software package: - Connection between the modules is established by use of transfer files (including IGES files for the connection with AutoCAD). Transfer files allow for maximum automatic work with minimum input data. - Interactive data entry is provided by use of menus and predefined Excel data sheets which allow very easy data input even for not very well experienced users, under the MS WINDOWS operating system. - Results of the calculations for all the modules can be first reviewed on the screen by use of MS Word text editor and after that printed. - Final results print outs for each of the modules represent final HVAC design documentation. - The most of the modules can be used independently from other modules.
- 3. 3 KLIMA Software – Language and possible Language translations: - Interactive Editor with Menu-s system, Data Input and Data Base Excel Sheets are in English language. Text that is supposed to be entered within Data input and Data Base Sheets can be in any language as selected within Excel by End User. All Fields description messages and all Fields error messages as results of primary logical control for the type of input text in the Fields and limitations for the minimum or maximum values of data entered in the Fields of Excel Data Sheets are in English language. - All formatted Results outputs are in Serbian and English languages and are printed in Word document File. - Error messages as results of detailed logical controls within ‘Fortran’ modules are printed before the Final results outputs into the Word document file. Those Error messages are in Serbian language and can be easily translated by use of, for example, ‘Google Translator’ to any available Language within the Language Translator. - Final formatted Results outputs from Serbian or English languages, after all Error messages from the Logical Controls are cleared and Data inputs rectified to give clear Final Word document Output File, can be further translated by End User with programming of MS Word Visual Basic Macro commands that will mainly contain ‘Find and Replace Text’ commands. Final formatted Results outputs after activation of ‘Find and Replace Text’ MS Word Macro commands can be in any Language as selected by End User. - End Users are encouraged to get in contact with us and to offer their MS Word Language Translation produced Macros to other ‘KLIMA Software’ users. - End Users are encouraged to provide support and trainings to other users.
