چکیده

The building sector accounts for more than ۳۳.۳۳% of final energy consumption, globally as the largest energy consumption sector. Among building elements, windows are considered as a key one in improving energy efficiency of the buildings and providing thermal comfort especially in the buildings with large glazing area. In order to increase the energy saving through fenestration systems, numerous active and passive techniques have been introduced and investigated by many researchers. Integration of energy efficient material like PCM (phase change material) into the glazing units is considered as one of these techniques. PCMs or phase change materials are potential to store and release a significant amount of energy during the phase change process due to their high heat of fusion. According to the studies investigated for this research, two types of PCMs are utilized in building constructions: Solid-Liquid PCMs (S-L PCMs) and Solid-Solid PCMs. Compared with S-L PCMs, the S-S PCM has advantages including: no leakage, less phase segregation, small volume change and no variation of optical properties. This research investigated the studies concerning the PCM-incorporated into glazing units (PCM_GU) and it highlighted the effective parameters on the energy performance of PCMs utilized in glazing units.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
