Abstract

Climate change has increasingly influenced thermal dynamics in both outdoor and indoor environments, leading to elevated indoor temperatures that can significantly compromise occupant thermal comfort. This comfort is intrinsically linked to psychological well-being, sleep quality, and overall productivity. Indoor thermal conditions are governed by multiple parameters, including internal and external heat gains, building envelope characteristics, and the effectiveness of ventilation systems. In response, the deployment and optimization of mechanical ventilation systems have become essential strategies in architectural and HVAC design to ensure better indoor environmental quality (IEQ). Moreover, energy-efficient mechanical systems are critical for minimizing operational energy consumption and also for mitigating greenhouse gas (GHG) emissions associated with building operations. This study employs Computational Fluid Dynamics (CFD) simulations to analyze the influence of mechanical ventilation placement on indoor temperature distribution, with a specific focus on enclosures with solar-exposed walls. The findings aim to inform design strategies for ventilation layout optimization that enhance thermal comfort while supporting energy-efficient and sustainable building practices. The research findings indicate that the position of the exhaust fan plays a crucial factor in thermal comfort. When it’s placed near to the heat source, it provides higher airflow near to the heat source that helps maintain temperature stability and prevent the spread of heat throughout the room.

Abstract

Peningkatan temperatur dalam ruangan akibat paparan panas matahari merupakan tantangan signifikan dalam manajemen kenyamanan termal. Penelitian ini bertujuan untuk menganalisis efektivitas posisi penempatan exhaust fan dalam mengendalikan temperatur ruangan menggunakan Prototype Studi dilakukan dengan tiga posisi variasi katub exhaust fan: dekat sumber pans, tengah, dan pangkal pada Prototype berukuran 30 cm x 30 cm x 25 cm. Parameter yang dikendalikan meliputi temperatur ruang Prototype 38°C. Hasil menunjukkan bahwa posisi exhaust fan memiliki pengaruh signifikan terhadap temperatur temperatur ruangan. Analisis pola aliran udara mengungkapkan bahwa penempatan exhaust fan pada posisi dekat sumber panas menghasilkan yang lebih optimtemperaur yang lebih stabil. Penelitian ini memberikan panduan praktis untuk optimasi penempatan exhaust fan dalam sistem ventilasi ruangan.
