A Ventilation and Cooling System with Dust-free Air for Residential Spaces of Asalouye City. دانشگاه علم و صنعت ایران. 1400; 1 (1)
چکیده:
High temperature and air pollution are the most important limitations of providing fresh air in the hot-humid climate of Asalouye City. This leads to the continuous use of mechanical cooling by the residents, and consequently, increases energy consumption and decreases the indoor air quality. Particulate Matter, Volatile Organic Compounds, and microorganisms are the three main categories of air pollutants. Fiber filters and Electro-filters are the most common methods of purifying PMs from the air. High efficiency, removal of a wide range of particles, low-pressure drop, and no need for replacement are the advantages of the electrostatic method. In this study, through simulation in Ansys-Fluent 2021 software, the performance of a cooling system which is designed with the combination of a window, an electrostatic precipitator, a cooling coil, and an exhaust fan was checked in reducing the concentration of PMs and pre-cooling the air before entering the building and providing the standard ventilation rate. The findings showed that at the air speed of 1m/s and 6m/s, the system can completely remove copper, nickel, and sulfur particles with a diameter of 0.1µ and 10µ. In addition, the distance between the air inlet of the system (window opening) and its air outlet (where air enters the interior) affects the reduction level of particles. The proposed cooling coil can reduce the air temperature by only 2°C. If there is no wind, an exhaust fan that provides a pressure jump equal to 250Pa to 500Pa will cause the airflow and provide the standard ventilation rate.
