V-KAT LEVHALI GÜNEŞ ENERJİLİ HAVA ISITICISININ ORTAM ISITMASI İÇİN TEORİK VE DENEYSEL İNCELEMESİ

Öz

Bu çalışma, 84 m2 alana sahip bir ofise ısıtma sağlamak için tasarlanan V-Kat levhalı güneş enerjili hava ısıtıcısının ısıl performansını incelemektedir. Hava ısıtıcısının ısıl performansı hem teorik hem de deneysel olarak incelenmiştir. V-Kat levhalı güneş enerjili hava ısıtıcıları daha önce ofislere ısıtma sağlamak için çalışılmamıştır. Dolayısıyla bu çalışma bu sistemleri bu amaç için inceleyerek literatüre katkı sunmayı hedeflemektedir. Ofisin ısıtma yükü, Energy Plus bina simülasyon yazılımı ile 4546 W olarak hesaplanmıştır. Hava ısıtıcısının ısıl performansı, hava ısıtıcısı enerji denklemlerinin geliştirilen MATLAB kodu kullanılarak çözülmesi ile ve aynı zamanda hava ısıtıcısı işletme değişkenlerinin (örn. bileşen sıcaklıkları, hava hızı vb.) ölçülmesi ile incelenmiştir. Hava ısıtıcısının her bir bileşeninin sıcaklığı, faydalı ısı üretimi, ısıl verim, ısıtma yükünü karşılamak için gerekli olan hava ısıtıcısı sayısı ve karşılık gelen alanın elde edilmesi amaçlanmaktadır. Deneysel incelemenin sonucunda ısıtma yükünü karşılamak için 16 m2 lik 9 adet hava ısıtıcısı gerekirken, teorik incelemede yükü karşılamak için10 m2 lik 6 adet hava ısıtıcısının gerekli olduğu sonucu ortaya çıkmıştır.

THEORETICAL AND EXPERIMENTAL INVESTIGATION OF V-CORRUGATED SOLAR AIR HEATER FOR SPACE HEATING

Öz

This work is an effort to investigate the thermal performance of a V-Corrugated Solar Air Heater (SAH), which is intended for supplying heating to an office space having a floor area of 84 m2. Thermal performance investigation has been carried out both theoretically and experimentally. V-Corrugated SAHs have not been investigated for space heating in offices, hence this study aims to contribute by proposing and promoting them for this purpose. The load of the office space has been evaluated by the Energy Plus building simulation program as 4546 W. Thermal performance of the SAH is investigated by solving the governing equations with developed MATLAB code and concurrently by carrying out real-time monitoring of the operating parameters (e.g. component temperatures, air speed, etc.) of the SAH. It is aimed to obtain the temperature of each component of the SAH, useful heat output, thermal efficiency, number of SAHs and the corresponding area that is necessary to meet the heating load. It is found that 9 SAHs with 16 m2 are required to supply the target load for the experimental case and 6 SAHs with 10 m2 for the theoretical case.
