ABSTRAK

Kajian ini bertujuan untuk mereka bentuk dan mengkaji prestasi pengumpul fotovoltan-terma (PV/T) dengan menggunakan reka bentuk pengumpul terma aliran air secara pilin. Reka bentuk pengumpul terma aliran air secara spiral telah dibina semula daripada reka bentuk penyelidik sebelum ini. Pengumpul terma ini menggunakan saiz tiub yang lebih besar dan jarak antara tiub lebih dekat berbanding dengan reka bentuk penyelidik sebelum ini. Pengumpul PV/T ini telah diuji di bawah tiga keamatan yang berbeza iaitu 300, 500 dan 700 W/m2 serta diuji pada kadar aliran jisim air yang berbeza iaitu 0.01, 0.02 dan 0.04 kg/s. Pada keadaan yang sama, kecekapan fotovoltan, terma dan tergabung juga menunjukkan nilai yang paling tinggi, iaitu 4.18%, 76.68% dan 80.86%. Kecekapan terma yang dihasilkan pada kajian ini lebih tinggi dibandingkan dengan kajian sebelumnya.

ABSTRACT

This study aimed to design and assess the photovoltaic-thermal (PV/T) collector performance using spiral thermal collector design. The design of the spiral water collector was rebuilt from previous researchers design. The thermal collectors use a larger tube size and the distance between the tubes closer than with previous researchers design. PV/T collector has been tested under three different intensities, which are 300, 500 and 700 W/m2 and also tested at three different water mass flow rates, which are 0.01, 0.02 and 0.04 kg/s. At the same circumstances, the efficiency of photovoltaic (PV), thermal and PV/T also shows the highest value, which are 4.18%, 76.68% and 80.86%. In this study, the result of thermal efficiency is higher than the previous study.
