Bu çalışmada 1.5 × 1.5 × 1.5 m boyutlarında prototip yalıtımlı bir güneş havuzu Süleyman Demirel Üniversitesi Kampus alanında kurulmuştur. Yalıtımlı güneş havuzunun üzerine, üst yüzey ısı kayıplarını azaltmak ve daha fazla güneş radyasyonunu havuz yüzeyine odaklamak amacıyla yalıtımlı ve yansıtıcı özelliği olan iki tane yarım yansıtıcılı ve yalıtımlı kapak ilave edilmiştir. Çalışmada ayrıca havuz performansını artırmak amacıyla bir bilgisayar modeli geliştirilerek optimum açı belirlenmiştir. Elde edilen teorik ve deneysel sonuçlar grafikler halinde verilmiştir.

Anahtar Kelimeler

Güneş havuzu, güneş radyasyonu, ısı transferi, güneş kollektörleri.
