Design and Implementation of a Novel Algorithm for Optimal Building’s HVAC Systems Selection

در اين مقاله، تاثير نوع سيستم تهويه مطبوع يك ساختمان بر كاهش ميزان مصرف انرژي آن مورد بررسي قرار مي گيرد و با استفاده از آن يك الگوريتم جديد براي انتخاب سيستم تهويه مطبوع بهينه ساختمان ارائه مي شود. اين الگوريتم قابليت اجرا براي ساختمان هاي در حال ساخت و ساختمان هاي ساخته شده را دارد. به منظور ارزيابي عملكرد روش پيشنهادي يك ساختمان مسكوني پنج طبقه در نظر گرفته شده و مراحل بر روي مدل اين ساختمان شبيه سازي شده است. مقايسه بين مدل و ساختمان واقعي كم تر از يك درصد خطا نشان مي دهد.

HVAC systems are the biggest energy consumers in buildings. Hence, reducing energy consumption in this sector, while maintaining thermal comfort can be one of the vital policies in order to use saved energy in industrial section. This paper, analyzes and compares the effect of using different HVAC systems on energy consumption reduction and introduces a new algorithm for choosing an optimal HVAC system for a building. A five story residential building in Tehran has been considered as a case study to analyze proposed algorithm performance.Detailed building’s data and specifications like design plan, materials and HVAC system must be considered to increase the accuracy of the model. The model is validated based on energy consumption which does not need sensors installation. The model could be used to analyze building thermal behavior, energy consumption optimization and designing control systems with high accuracy. The comparison between the model and building’s real energy consumption shows less than one percent error which is acceptable.
