Abstract

Masalah mendasar dari solar collector khususnya jenis solar collector plat datar adalah bagaimana meningkatkan kinerja efisiensinya semaksimal mungkin. Dalam meningkatkan kinerja ini para peneliti sebelumnya melakukan berbagai cara, diantaranya memodifikasi, menambah peralatan, menguji bahan yang digunakan. Dari semua studi jurnal yang terkait dengan masalah peningkatan kinerja ini penggunaan pipa air yang terhubung ke penyerap menggunakan pipa panas bulat, menyebabkan konduksi panas kurang efektif mengalir dari absorber ke pipa, selanjutnya karena bagian bawah secara langsung bersentuhan dengan insulasi sehingga luas permukaan konduksi dari pipa ke isolasi besar, tentu saja terjadi kehilangan energi dari solar collector. Penelitian ini fokus membuat fluid transfer heat transfer, memungkinkan untuk perpindahan panas yang lebih baik, serta menguji beberapa jenis cairan yang digunakan sebagai media transfer panas. Pengolahan data dengan uji statistik adalah ANOVA dari beberapa jenis fluida yang digunakan dan beredar pada solar collector plat datar dengan pipa persegi dengan sirip. Hasil pengujian dari analisis statistik dengan indikator perbedaan suhu penukar air inlet dan exchanger tidak menunjukkan perbedaan karena F tabel lebih besar dari F aritmatika. Dari ketiga jenis media yang diuji pada solar collector pipa persegi dengan sirip tidak mempengaruhi peningkatan efisiensi.
