Numerical Simulation of Indoor Comfort Based on FLUENT

Abstract

With the continuous development of the national economy, people's demand for using air conditioning systems to regulate thermal comfort in indoor buildings has been increasing, and related research is gradually deepening. However, there is still a lack of specific research on the thermal comfort of specific spaces such as bedrooms. According to research, humans spend about 80% of their lives indoors, so having good indoor conditions has become a key factor affecting the positive development of health, work, and learning efficiency [1]. In recent years, the use of numerical simulation software for numerical simulation analysis of indoor air conditioning to regulate thermal comfort and its application in solving practical engineering problems has gradually become a research hotspot. This method can quickly, efficiently, economically, and reliably simulate and predict indoor airflow distribution, providing safe, reliable, and comprehensive technical analysis results for relevant design departments. Due to the continuous advancement of computer technology and the deepening of research on indoor thermal comfort, the role of Computational Fluid Dynamics (CFD) simulation technology in enhancing thermal comfort and optimizing environmental design in building air conditioning system design will become increasingly significant. The main key factors affecting indoor thermal comfort include air temperature and humidity, wind speed, and thermal radiation. This paper will focus on regulating the temperature and airflow distribution of bedroom air conditioning systems and explore their impact on indoor comfort.
