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.

Abstract

Thermoelectrics can convert electrical energy to thermal energy. The generated thermal energy can be used in various cooling systems (TEC) applications. Improvement of TEC performance influenced by hot-side heat dissipation method, working fluid, and multi-thermoelectric. This study aims to investigate the relation between multi-thermoelectric configuration and the cooling behaviors. The experiment was conducted on the devices equipped with two modules of TEC arranged in series and parallel with variations of input voltage, working fluid mass flow, and temperature. The result reveals variations in cooling behaviors between the two configurations. Parallel configuration TEC gives the highest cooling capacity with a value of 66.62 W, 100% bigger than the series configuration. Meanwhile, the series configuration provides a delta temperature of 11.03 K, 2% higher than the parallel one. The parallel modules cooling performance is the biggest among the two arrangement, with a value of 2.57, which is 147% higher than series one.

Abstract

Indoor air quality has become a critical concern due to its significant impact on human health, as 80%-90% of human activities are conducted indoorsThis study aims to assess the air quality in a university classroom in Bandung City that utilizes passive ventilation, focusing on CO₂ concentration, temperature, and humidity parameters. A quantitative approach involving observational and experimental methods was employed by varying the opening levels of passive ventilation into three conditions: fully open, half-open, and fully closed. The results indicate that fully open ventilation effectively maintains good air quality with stable CO₂ concentration, temperature, and humidity. Conversely, under fully closed ventilation conditions, there is a significant increase in CO₂ concentration, temperature, and humidity, which can reduce comfort and pose health risks.The findings emphasize the importance of managing passive ventilation to ensure a healthy and comfortable classroom environment.
