Studi Eksperimental Pemanas Air Tenaga Surya Pelat Absorber Type Sinusoidal Dengan Variasi Terhadap Derajat Kevacuman Dan Aspect Ratio

Abstract

Sistem kolektor surya yang dirancang adalah kolektor dengan variasi tingkat kevakuman dan aspect ratio dengan tebal pelat (δ) 1 mm . Untuk tingkat pemvakuman -20 cm.Hg, -40 cm.Hg, dan -60 cm.Hg serta menggunakan aspect ratio 1, 1.33, dan 2. Pengambilan data dilaksanakan dengan memvariasi debit fluida kerja dengan mengatur bukaan katup, yaitu dari 100 cc/menit sampai 300 cc/menits kenaikan 100 cc/menit. Dengan pemvariasian tingkat kevacuman di antara pelat absorber dan kaca penutup, diharapkan dapat memperkecil koefisien kehilangan, temperatur absorber naik, dan temperatur kaca penutup turun. Sehingga dapat meningkatkan efisiensi kolektor. Sehingga kita dapat menyimpulkan bahwa pada tingkat kevacuman -60 cmHg efisiensi yang didapat lebih besar dibandingkan dengan tingkat kevakuman -20 cmHg dan -40 cmHg. Sedangkan untuk aspect ratio 2 memiliki efisiensi terbesar dibandingkan aspect ratio 1 dan 1,33
