Conditionnement d’air

Abstract

"The simulation tools are prominent in studies of optimization in building physics and in air conditioning systems. The approach to the optimal energy design of buildings and air conditioning systems member’s, results from the depletion of fossil energy resources and concern for the preservation of the environment that has only amplified their use. In many countries, especially Western countries, these tools found their place in the scientific community, have not yet found their place among the Algerian scientific community and especially among professionals. The challenge is to promote technology transfer of these tools. Unlike the use of a finished product (Black box), we should instead initiate a development methodology simulation tools. This will allow Algerian scientists soldered in the field of HVAC engineering, the use of design mechanisms that take into account new computer technology and provide training in the field of simulation. A wide range of simulation tools for energy performance of buildings and air conditioning systems, scientifically validated, are available around the world. We identify 360 simulation tools. Users of these tools are mainly researchers, physicists and experts. However, the literature and Comparative studies show that most practitioners are much more interested in (1) integration of intelligent design based on information and knowledge, (2) the friendliness and ease of use of the proposed user interfaces with these simulation tools. These two points are the main factors for identifying a simulation program as: 'user-friendly graphical interface (ICG)'. The classic modeling approach focuses in most cases, the description of a problem, its mathematical representation and numerical solution. The method described here incorporates the concept of understanding of the model by a user. In this approach, the modeler must keep in mind the profile of potential users of the model of the system and evaluate their skill level. Modeling a system before it is built sheds its operation. It is also a good way to master complexity and ensure its consistency. A model is a common, accurate and known language by all members of the development team. So it is a preferred vehicle for communication. This communication is essential to reach a common understanding and accurate to the various stakeholders of a given problem. In the field of software engineering, the model allows a better distribution of tasks and automates some of them. It is also a factor in reducing delays. The description of the model attaches great importance to the implementation of IT building- air conditioning system. It uses the techniques of Object oriented design described by the standards and specifications in UML 2.0 notation (Unified Modeling Language, Version 2006) and which are stored all the major players in the field, players who have also contributed to its development (IBM, Microsoft, Oracle, DEC, HP, Rational, Unisys etc.). The UML concept is a graphical language for representing and communicating the different aspects of system information. Implementation of ICG brings any time a new complexity in the task of development. The complexity lies in the description of multitasking dialogue that is executed by the user to carry out several tasks at once. At the level of the specification of the user interface, developers can design the interface. But it is often difficult to specify theirdynamic behaviors due to the complexity of the dialogue. Formal methods such as Petri-nets or Harel state diagrams will be of great use in the specification of the dynamic behavior before the implementation of the interface. This will reduce the testing time and improve the quality of the interface. The main contribution in this work, in addition to the methodological framework related to the iterative process proposed is the implementation of a new platform that allows the creation of Specific user interface prototype IDD file data entry of the energy performance of buildings and HVAC systems simulation program, EnergyPlus. UML and networks of Petri are used for the first time in the process of developing of a prototype of a user interface for program EnergyPlus. This methodology allows the generation of static and dynamic aspects of the GUI from the behavior specifications and data.
