Abstract
This paper focuses on the performance assessment of the green filtration system that incorporated with evaporative cooling that used to enhance indoor air quality. This system was invented in an attempt to thrive in a clean environment that becomes a solution for certain places. Indoor air quality (IAQ) and public health risk related to each other, it is due to the percentage of the city population that stays indoors rather than go outdoors. Indoor air contamination is originated from mixed origins such as volatile organic compounds (VOCs) and indoor airborne particulate matter (PM). The results show that the green filtration system manages to filter PM and VOCs in the air but not as efficient as modern air filters in the market. Furthermore, the evaporative cooling system possesses a huge deal in energy-saving within hot and arid climatic regions.
Highlights
Indoor air quality (IAQ) and public health risk related to each other, it is due to the percentage of the city population that stays indoors rather than go for outdoors, which is around 85 – 90 % [1]
A Passive green filtration system can treat indoor air pollutants, like volatile organic compounds (VOCs) that predominantly extracted by greenery rhizosphere bacterium colony [4], plus CO2 which discarded along photosynthesis process [5]
This paper presents an experimental assessment on green filtration systems with evaporative cooling in terms of several affecting factors for air filtration such as temperature, humidity, air velocity, particulate matter (PM) removal, CO2 level, volatile organic compounds (VOCs) and feasibility analysis on evaporative cooling in Malaysia
Summary
Indoor air quality (IAQ) and public health risk related to each other, it is due to the percentage of the city population that stays indoors rather than go for outdoors, which is around 85 – 90 % [1]. A Passive green filtration system can treat indoor air pollutants, like volatile organic compounds (VOCs) that predominantly extracted by greenery rhizosphere bacterium colony [4], plus CO2 which discarded along photosynthesis process [5]. It is unmanageable to achieve the correlative outcome for the humid region because near-saturated conditions are demanded temperature drop needed. In such situation, hybrid structure like desiccant in the form of evaporative cooling are desired. This paper presents an experimental assessment on green filtration systems with evaporative cooling in terms of several affecting factors for air filtration such as temperature, humidity, air velocity, particulate matter (PM) removal, CO2 level, volatile organic compounds (VOCs) and feasibility analysis on evaporative cooling in Malaysia. The outcome of this study focusing on providing a better understanding of green filtration comes with a cooling system
