“…Panas yang diserap oleh PCM dapat digunakan kemudian untuk aplikasi lainya karena prinsipnya PCM dapat menyimpan panas yang diterima [13]. Pada penelitian lainnya, media air dialirkan melalui pipa berdiameter kecil diletakkan berdempetan dibagian bawah panel surya sebagai heat sink juga menunjukkan hasil pelepasan panas dari panel surya sebesar 1 kW dan dapat menurunkan temperature panel sekitar 40°C [14]. Media udara sebagai upaya peningkatan performa panel telah dilakukan.…”

“…Hal ini dikarenakan temperatur panel turun seiring kenaikan kecepatan udara. hal ini juga diperkuat oleh penelitian lainnya yang menyebutkan bahwa peningkatan rata-rata efisiensi listrik yang paling besar terjadi pada saat penurunan rata-rata temperature paling rendah [6], [14]. Disamping itu, dari Gambar 4 dan 5 dapat dilihat bahwa daya keluaran dan efisiensi di setiap kecepatan, terlihat menurun.…”

The rapid development of technology, sunlight can be converted into electrical energy. But there are problems that arise in the performance of solar panels, one of which is the panel temperature is too high. Therefore to overcome the decrease in performance, the panel temperature needs to be maintained. In this study aims to analyze the temperature settings on solar panel cooling using variations in air velocity to improve photovaltic performance. Solar simulators is used in this ekperiment and carried out in a closed room conditions. solar panel is placed in a special box called a cooler box and four thermocouples are placed at the top of the panel and 2 others at the bottom of the panel to evaluate the temperature changes that occurs on the panel. An air blower is combined with an anemometer to provide variations in air velocity for cooling the panels. From the results of solar panel testing without cooling obtained in the temperature range of 38 - 52.875⁰C produces electrical efficiency ranging from 3.014 - 3.134%. Whereas in testing using cooling with varying air velocity of 2, 3, 4, and 5 m/s in the temperature range of 33.43 -40.5°C produces electrical efficiency ranging from 3.106 - 3.206 %.

Fifteen years ago, polymeric hollow fibre heat exchangers were presented for the first time. Nowadays there are not only the shell-and-tube types as there were at the beginning. In this paper, six chaotised polymeric hollow fibre bundles with a different number of fibres were studied. The bundles presented varied in their fibre diameter, number and shape. These bundles were fixed into the module in such a way that the middle part serves as a cross-flow heat exchanger in an air tunnel. They were tested for air-water application with three different airflow rates. The overall heat transfer coefficients were determined, and the inner and outer heat transfer coefficients were derived. The modules presented achieved a heat transfer rate of up to 1309 W. The overall heat transfer coefficient reached a maximum of 339 Wm−2 K−1.

“…All these features allow PHFHE to compete on an equal footing with metal heat exchangers. PHFHE can be applied in such fields as heat recovery systems [6], evaporative cooling systems, desiccant cooling systems, and electronic device cooling [7], [8]. Also, PHFHEs with a membrane polymeric hollow fibers can be applied for filtration processes, chemical separation or medical treatment [9][10][11].…”

The results of the development and experimental investigation of a polymeric hollow fibre heat exchanger are presented. A heat exchanger of a shell-and-tube type with an outer diameter of 80mm and a length of 350mm containing 2200 206mm-long polyamide hollow fibres with an outer diameter of 0.8mm cross-wound at an angle to the axis of the heat exchanger. Cross-winding was realized with the help of the modified winding system X-Winder. Cold water with a temperature of 13°C and a constant flow rate of 2160l/h was fed through the hollow fibres. The dependences of heat transfer characteristics on the shell fluid temperature and fluid flow rate are presented. The device was able to transfer 38kW at a shell water temperature of 70°C and a shell fluid flow rate of 800l/h. In these conditions, the maximum overall heat transfer coefficient reaches 1950W/m²K.
