3D打印相变储能混凝土对室内温度调控的模拟
Simulation Study on the Temperature Regulation of 3D Printed Phase Change Energy Storage Concrete
摘要
Abstract
3D printed concrete has gained significant attention in recent years due to its promising applications in construction engineering.However,the research on its thermal performance remains limited.This study proposes an innovative approach to enhance building thermal inertia by incorporating phase change materials(PCMs),which can effectively improve indoor thermal comfort and reduce energy consumption.Using self-developed coarse aggregate 3D printed phase change concrete,we established numerical models in COMSOL multiphysics to investigate the temperature regulation mechanism.The effects of PCM content(particularly hollow ceramsite composite PCM,HCCP)and wall thickness on indoor temperature fluctuations were systematically analyzed,with special emphasis on evaluating the effectiveness of HCCP in large-scale models.The results demonstrate that 40%HCCP incorporation effectively controls indoor temperature fluctuation within 4.6℃,achieving a remarkable 63.8%reduction compared to the control group.When the wall thickness increased by 20%,the temperature fluctuation decreased by 6.7%in the control group and by 13.4%in the 20%HCCP group.The incorporation of HCCP can also effectively mitigate indoor temperature fluctations in large-scale models,while exhibiting a more pronounced regulation effect in compact spaces.These findings provide crucial theoretical guidance and practical references for optimizing the design of 3D printed phase change energy storage concrete structures.关键词
