Year 2019, Volume: 2 Issue: 2, 87 - 93, 28.12.2019

Abstract

Bu makale duvarlardaki farklı yalıtım malzemelerinin karşılaştırmalı teorik ısı transferi çalışmasını sunmaktadır. Çalışma için seçilen malzemeler aerojel, taşyünü, cam yünü, koyun yünü, kenevir, keten, cüruf yünü, cam elyaf, fenolik köpük, vermikülit, PUF / PIR köpük, polistiren köpük, talaş, perlit, polyester, karton ve mantardır. Bu çalışmada, çimentolu sıva, kırmızı tuğla / uçucu tuğla, çimento sıva, kontrplak, yalıtım malzemesi tabakası ve alçıpan çok tabakalı, yani farklı yalıtım malzemeleri ile değişen beşinci tabakalar hariç tüm tabakaların aynı olduğu altı tabaka kombinasyonu tanıtılmıştır. Çalışmadan, tuğla duvarın kırmızı tuğla duvardan daha düşük ısı transferine sahip olmasına rağmen, yalıtım katmanı olmayan kırmızı tuğla duvar ve uçucu tuğla duvarın daha yüksek ısı transferine sahip olduğu sonucuna varılabilir. Kırmızı tuğla duvar söz konusu olduğunda, aerojelli duvar en düşük ısı transferine sahiptir ve 100C’de 2.53 W ve 300C’de 7.60 W ve vermikülitli duvar 100C’de 9.28 W ve 27.83at 300C’de en yüksek ısı transferine sahiptir. Uçucu tuğla durumunda, aerojelli duvarın en düşük ısı transferi 100C’de 2.43 W ve 300C’de 7.28 W’dir ve vermikülitli duvar 100C’de 7.97 W ve 300C’de 23.91 W olan en yüksek ısı transferine sahiptir.

Investigation Of The Availability Of Vermiculite In Thermal Insulation Technologies

Year 2019, Volume: 2 Issue: 2, 87 - 93, 28.12.2019

Abstract

Buildings are aimed to provide shelter against the weather and climatic vagaries but at the same time a good building construction should provide thermal comfort in an energy efficient way. One of the major components of building envelope is walls which plays an important part in heat transfer. If thermal resistance of walls is high the indoor environment can be maintained at desired levels of temperature with minimum energy requirements. In order to improve the building thermal efficiency it is important to improve the thermal resistance of the walls through use of suitable insulating materials. This paper presents a comparative theoretical heat transfer study of different insulating materials in walls. The materials chosen for study are aerogel, rockwool, glass wool, sheep wool, hemp, flax, slag wool, fiber glass, phenolic foam, vermiculite, PUF/PIR foam, polystyrene foam, sawdust, perlite, polyester, cardboard and cork. Present study introduced multilayer of cement plaster, red brick/flyash brick, cement plaster, plywood, insulating material layer and gypsum board i.e. six layers combination have been introduced in which all layers are same except fifth layers which is varied by different insulating materials. From the study, it can be concluded that red brick wall and flyash brick wall without insulating layer has higher heat transfer although flyash brick wall has lower heat transfer than red brick wall. In case of red brick wall, wall with aerogel has the lowest heat transfer and it is 2.53 W at 100C and 7.60 W at 300C and wall with vermiculite has highest heat transfer which is

9.28 W at 100C and 27.83at 300C. In case of flyash brick, wall with aerogel has lowest heat transfer which is 2.43 W at 100C and 7.28 W at 300C and wall with vermiculite has highest heat transfer which is 7.97 W at 100C and 23.91 W at 300C.
