Numerical investigation of an air cleaning device performance

Öz

In this study, a portable air cleaner's performance for cleaning a room air with a person sitting in it was investigated. The effect of different blowing angles and air velocities from the device fresh air supply vent on the cleaning performance of the device was studied. In this context, clean air delivery rate (CADR) and air age parameters were used. It has been determined that suppling the cleaned air at different angles and velocities affects the device's performance according to results from analysis and calculations. It has been observed that the mean air age in the room is inversely proportional to the supply air velocity. As the supply air velocity increases, the mean air age decreases by half. The most suitable air supply velocity and angles were determined by comparing the CADR and air age values.

Hava temizleme cihazının performansının sayısal incelenmesi

Öz

Bu çalışmada içinde oturan insan olan bir odanın havasının temizlenmesinde kullanılan taşınabilir hava temizle cihazının performansı incelenmiştir. Cihazın temiz hava besleme menfezinden farklı üfleme açıları ve üfleme hızlarının cihazın temizleme performansına etkisi araştırılmıştır. Bu kapsamda temiz hava dağıtım oranı (CADR) ve hava yaşı parametreleri kullanılmıştır. Yapılan analizler ve hesaplamalar çerçevesinde temizlenmiş havanın farklı açı ve hızlarda üflenmesi cihaz performansını etkilediği tespit edilmiştir. Oda içerisinde ortalama hava yaşı üfleme hızı ile ters orantılı olduğu görülmüştür. Üfleme hızı arttıkça ortalama hava yaşında yarı yarıya azalma meydana gelmektedir. Temiz hava dağıtım oranı ve hava yaşı değerleri karşılaştırılarak en uygun üfleme hız ve açıları belirlenmiştir.
