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.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh desikan terhadap penyerapan uap air dan penurunan beban laten yang dilakukan pada Air Handling Unit (AHU). Upaya yang akan dilakukan yaitu menggunakan desikan jenis silica gel pada ducting bagian outside air yang telah tersedia, sehingga udara tersebut akan diserap kadar uap airnya oleh desikan yang mengakibatkan kadar uap air menurun dan kualitas udara menjadi lebih kering. Hasil yang diperoleh dari pengujian desikan pada AHU adalah adanya penurunan kelembaban yang memiliki nilai tertinggi 165 g/s dan penurunan beban laten 380,20 kW lalu beban koil 116,65 kW dengan persentase penurunan beban koil sebesar 41%.
