ABSTRACT It is known that various plants have purification ability for indoor air pollutants. In this paper the purification mechanism of foliage plant was investigated by analyzing bioelectrical potential. It was first shown that the air purification ability of a plant depends on various environmental conditions, especially on light irradiation. It was then clarified that the bioelectrical pot...
The next generation of conventional submarines will be submerged for several weeks, creating a need for regenerative air purification methods and new air monitoring instruments. Submarine air is a complex mixture of compounds, where the most obvious contaminant is metabolically produced carbon dioxide. Normal eight-hour occupational exposure limits are not applicable on a submarine, instead spe...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Background and aims: Bio aerosols in the workplace of health-care workers is one of the hazardous agents that needs more research. .This study investigated the feasibility application of the Iranian natural zeolites (INZ) for purification of air contaminated with seudomonas aerognisa. Methods: In this study INZ was prepared in laboratory conditions. The INZ crushed and pulverized using grin...
A novel air-cleaner with a coil-shape photocatalysis-plasma synergistic reactor was developed. The air-cleaner showed 95% ± 1% reduction of a TVOCs concentration in tobacco smoke at “single-pass” condition. Air-purification activity of the air-cleaner was stably-maintained after the treatment of 12,000 cigarettes of tobacco smoke.
Introduction: The subject of this research is having healthy air and its challenge is air purification to have this type of air. Healthy air is free of any pollutants, including odors, harmful gasses, dust, and viruses, especially corona. This healthy air is provided by a purifier device. One of the problems of metropolises is the lack of healthy air, which is one of the most important human ne...
