Abstract

Penelitian ini bertujuan untuk menganalisis kinerja solar heat exchanger (SHX) dengan menggunakan fluida nano sebagai cairan pendingin (nano-coolant). SHX berfungsi sebagai sarana penyerap panas dari panel surya. Desain SHX disesuaikan untuk panel surya dengan kapasitas 20 Wp, yaitu 35 x 45 cm. Nano-coolant yang dipersiapkan yaitu campuran 0.5% Al+etilen glikol/air (10:90). Metode uji eksperimental dilakukan untuk kinerja fluida dan SHX dengan variasi laju aliran volumetrik 1−3 LPM, dengan suhu saluran masuk fluida dipertahankan pada 35°C. Hasil penelitian didapatkan model solar heat exchanger (SHX) sebagai alat perpindahan kalor telah berhasil melakukan penyerapan panas secara maksimal dengan desain yang dibuat berliku, untuk memperluas area sentuh pada panel surya. Nano-coolant telah mencapai performa terbaik dibandingkan cairan dasar EG murni. Peningkatan terjadi sebesar masing masing 9.29, 10, dan 10.64% dibandingkan dengan EG yaitu 4.29, 5.71, dan 6.4% pada laju aliran 1, 2, dan 3 LPM. Penurunan tekanan yang terjadi dibandingkan pada cairan dasar saat laju aliran 1 LPM, dan diperoleh pressure drop nano-coolant (ΔPnc) lebih tinggi 3% dibandingkan pressure drop EG (ΔPEG).

Abstract

The potential of solar energy in Indonesia is quite large as a renewable energy source, usually called solar panels or photovoltaic (PV) technology as a device capable of converting solar radiation into electrical energy. When solar panels operate, only about 15% of solar radiation is converted into electrical energy, while the rest is converted into heat. The intensity of solar radiation and the temperature of the surrounding air affect the voltage and current produced by solar cells. This condition requires a device that can regulate the temperature state of the solar panel. This study was conducted to overcome the heat problem in solar panels through optimizing the thermal properties of the cooling fluid by adding nano-sized SEM/EDS-tested particles to the W/EG base fluid, which is commonly called nanofluids, then making serpentine channels as a heat exchanger was also carried out. The experimental test process was carried out with a flow rate variation of 1 to 3 LPM and the inlet temperature was kept at 35˚C. The results showed that the highest cooling fluid flow rate was the most optimum condition. The Reynolds number shows that the heat transfer coefficient increases by 1011.72 W/m◦K, 1321.72 W/m◦K, and 2070.39 W/m◦K, respectively. The Nusselt number tends to increase as the Reynolds number of the nanofluid increases. An increase in Nusselt number indicates an increase in heat transfer coefficient, while Reynolds number indicates laminar flow of the coolant. Similarly, the pressure drop increases with increasing flow rate.
