| Abstract: | Pada alat pengering tipe bak, blower berfungsi sebagai penyalur udara panas
selama proses pengeringan. Sistem aliran udara yang terjadi di dalam alat pengering
akan mempengaruhi proses pengeringan, sehingga dibutuhkan karakteristik dan
penggunaan blower untuk dapat memaksimalkan sistem. Tujuan dari penelitian ini
adalah untuk menentukan karakteristik blower tipe sentrifugal satu sumbu,
mengetahui karakteristik sistem aliran udara pada bak pengering-PV/T, dan
mengetahui kinerja PV/T dalam menghasilkan listrik untuk penggunaan blower.
Tahap dari penelitian ini yaitu mengukur karakteristik blower dengan laju aliran
udara yang berbeda, menganalisis sistem aliran udara, dan mengukur penggunaan
blower terhadap PV/T. Hasil penelitian menunjukkan tekanan statis dan tekanan
total akan turun seiring naiknya laju aliran udara, sementara tekanan dinamis akan
naik. Efisiensi blower dipengaruhi laju aliran udara dan daya yang diterima blower.
Sistem aliran udara mengalami penurunan tekanan akibat panjang saluran, belokan,
dan perubahan bentuk penampang. Ketika daya PV/T lebih kecil dari blower maka
blower akan mengambil daya dari baterai. Ketika daya PV/T lebih besar dari blower
maka daya yang tidak digunakan blower akan disimpan di dalam baterai. Efisiensi
blower selama waktu kerja alat pengering dengan tumpukan 30 cm hari pertama
38%, hari kedua 41,21%, sedangkan pada tumpukan 15 cm sebesar 48,36% dan
hari kedua 53,35%. In Bed drying system, the blower functions as a hot air distributor during the drying process. The airflow system within the dryer affects the drying process, so the characteristics and use of the blower are needed to maximize the system. The objective of this study is to determine the characteristics of a single-axis axial blower, understand the airflow system characteristics in the bed drying with PV/T, and assess the performance of the PV/T system in generating electricity for blower use. The stages of this study include measuring the blower's characteristics at different airflow rates, analyzing the airflow system, and measuring the blower's impact on the PV/T system. The results show that static pressure and total pressure decrease as airflow rate increases, while dynamic pressure increases. Blower efficiency is influenced by air flow rate and the power received by the blower. The airflow system experiences pressure loss due to the length of the duct, bends, and changes in cross-sectional shape. When the PV/T power is less than the blower power, the blower will draw power from the battery. When the PV/T power is greater than the blower, the unused power is stored in the battery. The blower efficiency during the operation of the dryer with a 30 cm pile on the first day was 38%, on the second day 41.21%, while for a 15 cm pile it was 48.36% on the first day and 53.35% on the second day. |
