Abstract

The water crisis is a significant global problem, with more than 2 billion people lacking water and 1.1 billion having no access to clean water. Desalination, a method of converting seawater into fresh water by removing salt, is a potential solution to help coastal populations. This study aims to determine the convection and evaporation heat transfer coefficients and the effect of condenser cooling water temperature on the evaporation process and the increase in freshwater condensate. The research methodology involved the analysis of heat and mass transfer in a solar desalination system. A desalination device was designed to test the evaporation process with seawater temperature heated using halogen lamp light. Results show that increasing seawater temperature from 27°C to 42°C results in condensation when the temperature reaches about 30°C, affecting the water surface pressure and evaporation rate. Evaporation and condensation efficiencies are affected by convection and evaporation heat transfer, resulting in a convection heat transfer (0.84296 W/m2. °C) and evaporation heat transfer coefficient (23.81353 W/m2.°C). This research demonstrates the potential of solar desalination technology in producing clean water.

Abstract

Air bersih semakin langka di seluruh dunia akibat polusi, perubahan iklim, dan pertumbuhan penduduk. Salah satu solusi adalah desalinasi air laut dengan metode solar still yang ramah lingkungan. Penelitian ini fokus pada forced flow solar still yang memanfaatkan aliran udara untuk meningkatkan laju penguapan dan produktivitas air tawar. Temperatur air mempengaruhi kinerja solar still; semakin tinggi temperatur air dan kecepatan aliran udara di dalam solar still, maka penguapannya juga akan meningkat. Penelitian ini bertujuan menentukan laju penguapan air laut dalam forced flow solar still. Perangkat desalinasi ini menggunakan kondensor dan pengukuran parameter seperti temperatur dan kecepatan aliran udara, dengan data penguapan dikumpulkan setiap 15 menit selama 2 hari. Hasil penelitian menunjukkan bahwa forced flow solar still efektif meningkatkan laju penguapan. Temuan ini dapat membantu meningkatkan efisiensi desalinasi menggunakan solar still dengan mempertimbangkan faktor iklim lokal.
