Abstract


Phase change materials (PCM) mendapat banyak perhatian dalam penggunaannya sebagai penyimpan energi termal karena densitas energi per unit massa/volume yang tinggi. Pemanfaatan PCM sebagai penyimpan energi termal dapat diterapkan pada tangki penyimpan air, solar collector dan pipework terisolasi. Di dalam studi ini parameter pelelehan paraffin wax RT52 yang merupakan salah satu jenis PCM diprediksi menggunakan sebuah model simulasi solar water heater sistem aktif yang berisi susunan kapsul PCM berbentuk silinder banyak. Pemodelan simulasi pelelehan PCM menggunakan metode enthalpy-porosity. Laju aliran heat transfer fluid (HTF) divariasikan dan fluks kalor dijaga konstan 1000 W/m2. Hasil simulasi menunjukkan bahwa laju aliran HTF 4 lpm, 3 lpm, dan 2 lpm memiliki perbedaan waktu pelelehan yang tidak terlalu signifikan yaitu 10,3% dan 5,7%. Perbedaan temperatur antara HTF dan PCM sebesar 7,5 K menjadi titik puncak bagi fluks kalor permukaan yaitu 433,7 W/m2.
