Abstract:
High temperatures and air pollution are significant challenges in ensuring fresh air supply in the hot-humid climate of Asalouye City. These conditions compel residents to rely heavily on mechanical cooling, which subsequently escalates energy consumption and deteriorates indoor air quality. The primary air pollutants include Particulate Matter (PM), Volatile Organic Compounds (VOCs), and microorganisms. Fiber filters and electrostatic filters are the most common methods for purifying PMs from the air, with the electrostatic method offering advantages such as high efficiency, the ability to remove a wide range of particles, low-pressure drop, and no need for frequent replacement. This study proposed a ventilation system integrating a window,
a precipitator using electrostatic technology, a cooling coil, and an exhaust fan. The system's performance was evaluated using CFD simulation in Ansys-Fluent software (2021) to assess its effectiveness in reducing PM concentrations, pre-cooling incoming air, and maintaining the standard ventilation rate. The findings revealed that at air velocities of 6 m/s and 1 m/s, the system could completely remove copper, nickel, and sulfur particles with diameters of 0.1 µ and 10 µ. Additionally, the distance between the system's air inlet (window opening) and its air outlet (where air enters the interior) significantly influences the particle reduction level. The proposed cooling coil, however, only managed to reduce the air temperature by 2°C. In the absence of wind, an exhaust fan with a pressure jump of at least 250 Pa or 500 Pa is necessary to achieve the standard airflow and ventilation rate.
