Simulasi Numerik Distribusi Polusi Udara Dalam Ruangan

Abstract

The kitchen is a vital area that provides energy sources through food processing for residences. However, the cooking process can also produce pollutants that are harmful to the body. This study aims to investigate the concentration and distribution of contaminants (CO and CO2) generated from the kitchen to all rooms in the house. In addition, Air temperature and velocity are investigated to observe their relationship with the distribution of pollutants. The investigation procedure utilizes a numerical simulation of a dwelling with two different ventilation cases. The simulation results show no significant difference in air velocity between the two cases. While the addition of natural ventilation in the kitchen area can reduce CO and CO2 concentrations throughout the room by 25.8% and 24.9%, respectively. On the other hand, the indoor air temperature can also be reduced by 4.9% with the same treatment. In conclusion, the addition of a window in the kitchen area has a significant impact on reducing temperature and pollutant concentrations all over the room.

“…Penelitian sebelumnya tentang Analisa Kinerja Cooling Tower P.A Hlton Dengan Variasi Laju Aliran Udara Dan Variasi Temperatur Air Masuk Terhadap Efektivitas ditunjukkan oleh Hidayat [3] yang menganalisa kinerja cooling tower, pengukuran kinerja dicoba dengan bersumber pada perhitunganperhitungan sehingga diketahui nilai approach, range dan efektivitas. Terdapat juga penelitian tentang efektifitas cooling tower melalui analisa Simulasi Numerik dan Validasi Experimental Distribusi Aliran Udara di dalam Cooling Tower yang diteliti oleh Prasetyo, 2007 [4] untuk memperbaiki desain distribusi aliran udara untuk meningkatkan kinerja cooling tower.…”
