Abstract

HVAC system design and optimization of the ventilation and air-conditioning of indoor environments are crucial for human comfort. Especially in recent years, due to the Covid pandemic, the importance of this hot topic is noticed. This study aims to focus on the HVAC performance of a dorm compartment onboard a naval surface ship since the ship environment is a good example of indoor air ventilation problem. The HVAC performance was investigated using a RANS solver. The numerical analyses were conducted for different scenarios and the results were finally discussed in terms of HVAC system location, air temperature, air intake and outlet conditions. As a conclusion, the current HVAC system design was found insufficient and alternative solutions were proposed in order to improve indoor air quality and thermal comfort.

Özet

Kapalı mekanlarda HVAC sistem tasarımı ve havalandırma ile iklimlendirmenin optimizasyonu insan komforu için önemlidir. Özellikle geçtiğimiz birkaç yılda yaşanan Kovid pandemisi nedeniyle bu güncel konunun önemi fark edilmiştir. Bu çalışma bir savaş gemisi içerisinde bulunan ve yatakhane olarak kullanılan bir kompartımanın HVAC performansı üzerine odaklanmaktadır. Savaş gemisi kompartımanı, kapalı mekan havalandırma problemi için iyi bir örnek teşkil etmektedir. HVAC performans analizi bir RANS çözücü kullanılarak yapılmıştır. Sayısal analizler farklı senaryolar için gerçekleştirilmiştir ve sonuçlar HVAC sisteminin yeri, hava sıcaklığı, hava giriş ve çıkış koşulları açısından tartışılmıştır. Sonuç olarak mevcut HVAC tasarımının yetersiz olduğu tespit edilmiş ve kapalı mekandaki hava kalitesinive ısıl konforu iyileştirmek amacıyla alternatif çözümler önerilmiştir.
