Abstract

In this study, energy and exergy analysis of HVAC systems used in Qaladze hospital in Sulaymaniyah, Iraq were done by using the first and second laws of thermodynamics. The average values of thermal energy and exergy efficiencies for the boiler and air handling units were found as 89%, 19.5% and 81.5%, 24%, respectively. The cooling coefficient of performance of the chiller group was calculated as 4.82 on average. It was determined that HVAC systems generally provide thermal comfort in the hospital. But it was concluded that all components of HVAC systems should be constantly checked to improve the thermal conditions and indoor air quality in the hospital.

Abstract

Bu çalışmada, Irak, Süleymaniye’deki Qaladze hastanesinde kullanılan HVAC sistemlerinin enerji ve ekserji analizleri termodinamiğin birinci ve ikinci yasalarına göre yapılmıştır. Yapılan analizlere göre kazan ve klima santralleri için ortalama ısıl enerji ve ekserji verimleri sırasıyla %89, %19,5 ve %81,5, %24; chiller grubunun soğutma performans katsayısı ortalama 4,82 olarak hesaplanmıştır. HVAC sistemlerinin genel olarak ısıl konforu hastanede sağladıkları tespit edilmiştir. Ancak hastanedeki iç hava kalitesini ve ısıl koşullarını iyileştirmek için HVAC sistemlerinin tüm bileşenlerinin sürekli kontrol edilmesi gerektiği görülmüştür.
