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. |
