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
W/m2, 500
W/m2 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.
