Özet

Bu çalışmada bakır borulu kelebek vakumlu borulu güneş enerjili hava ısıtıcısının (BETSAH-CT) performansı araştırılmıştır. Deneysel analiz 10 ila 50 kg/saat arasında değişen hava akış hızlarında gerçekleştirilmiştir. CT konfigürasyonunun çıkış sıcaklığı, termal ve efektif verimlilikler, ısı kazancı ve basınç düşüşü üzerindeki etkisi incelenmiştir. BETSAH-CT, 10 kg/saat'te 110,1 °C'lik maksimum çıkış hava sıcaklığına ve 10 kg/saat'te 89,7 °C'lik ortalama sıcaklığa ulaşmıştır. En yüksek faydalı ısı kazancı 50 kg/saat'te 663,8 W olarak kaydedilmiştir. Termal verimlilik hava akış hızıyla artmış ve 50 kg/saat'te %54,2'lik bir anlık tepe verime ulaşmıştır. Basınç düşüşü ve pompalama gücü hususları hava akışının ideal sistem performans oranını ön plana çıkarmaktadır. Ekserji verimliliği eğilimleri güneş ışınımı eğilimlerine neredeyse benzerdir ve ekserji verimliliğinin en yüksek değerleri akış hızıyla azalmaktadır. Sonuçlar, BETSAH-CT tasarımının termal verimliliği ve ısı kazanımını iyileştirme avantajına sahip olduğunu ve bu sayede güneş enerjisiyle hava ısıtmada sürdürülebilir ve enerji açısından verimli bir çözüm olarak kullanılabileceğini göstermektedir.

Abstract

This study investigates the performance of butterfly evacuated tube solar air heater with copper tubes (BETSAH-CT). The experimental analysis was conducted in across varying air flow rates ranging from 10 to 50 kg/h. The effect of CT configuration on outlet temperature, thermal and effective efficiencies, heat gain and pressure drop was examined. The BETSAH-CT achieved a maximum outlet air temperature of 110.1 °C at 10 kg/h and an average temperature of 89.7 °C at 10 kg/h. The highest useful heat gain noted as 663.8 W at 50 kg/h. The thermal efficiency increased with air flow rate, reaching a peak instantaneous efficiency of 54.2% at 50 kg/h. The considerations of pressure drop and pumping power bring to the fore the ideal system performance rate of airflow. The trends of exergy efficiency are nearly similar to the trends of solar irradiance and the highest values of the exergy efficiency decreases with the flow rate. The results indicate that the BETSAH-CT design has the benefit of improving thermal efficiency and heat gain, which can be used as a sustainable and energy-efficient solution to solar-air heating.
