Thermal Performance Analysis of Phase Change Material/Biochar Composite for CLT Application

Abstract

For carbon neutrality, it is important to continuously utilize wood with a high carbon stock. CLT using low-grade wood is an eco-friendly building material that can accelerate the realization of high-rise wooden buildings and carbon neutrality. In this study, basic studies were conducted to apply PCM, which stores thermal energy in the form of latent heat, to CLT to improve the low thermal storage performance of wood materials. To prevent leakage of liquid PCM, Biochar, a porous material, can be produced by pyrolysis of various biomass, and in this study, biochar obtained by low-temperature pyrolysis was used. The thermal properties of PCM/biochar composites were analyzed through DSC, TGA, FT-IR, and SEM. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
