Küçük Bir Güneş Bacasının Sıcaklık Dağılımlarının İncelenmesi

Çevre dostu ve sürdürülebilir enerji politikaları gün geçtikçe önem kazanmaktadır. Elazığ'da yapılan prototip bir güneş bacası, sıcaklık dağılımı ve güneş baca etkinliği açısından deneysel olarak incelenmiştir. Elazığ, sıcaklığın -15 ° C ile + 42 ° C arasında değiştiği üçüncü derece gün bölgesindedir. Deneysel sonuçlar, güneş baca yüksekliğinde bir artışla verimliliğin arttığını göstermiştir. Verim, baca yüksekliğine ve ortam sıcaklığına bağlıdır. Baca yüksekliği ne kadar yüksek olursa verimlilik o kadar fazla olur. Bununla birlikte, ortam sıcaklığının verimlilik üzerine etkisi çok düşük görünmektedir. Güneş baca sisteminin Elazığ şartlarında enerji üretimi için alternatif bir sistem olabileceği görülmüştür.

Investigation of the Temperature Distribution of a Small Solar

Environmental friendly and sustainable energy policies are gaining importance day by day. A prototype solar chimney constructed inElazig is investigated experimentally in terms of temperature distribution and solar chimney efficiency. Elazig is in the third degreeday region where the temperature varies between -15 ° C and + 42 ° C. The experimental results showed that the efficiency depends onheight of the chimney and the temperature of ambient. The higher the height of the chimney, the more is the efficiency. However, theeffect of ambient temperature on the efficiency seems to be very low. It was seen that, solar chimney system can be an alternative systemfor energy production under Elazig conditions.
