Abstract

Air bersih merupakan keperluan sehari-hari masyarakat terutama untuk minum dan memasak terutama bagi masyarakat yang berada di kawasan pesisir pantai dan kepulauan. Sedangkan garam merupakan sumber elektrolit bagi tubuh manusia. Kebutuhan akan garam dan air tawar masih belum dapat terpenuhi oleh pemerintah. Untuk memenuhi kebutuhan garam dalam negeri saja Indonesia masih harus mengimpor garam. Hal ini sangatlah tidak wajar bagi Indonesia sebagai negara maritim yang memiliki laut dan pantai terpanjang nomor dua di dunia. Air laut yang tersedia sangat banyak dapat diolah menjadi air tawar dan garam. Ada beberapa cara untuk mengolah air laut menjadi air bersih dan garam, salah satunya dengan cara destilasi. Proses destilasi air laut memerlukan energi panas untuk menguapkan air laut sebelum diembunkan dan menghasilkan air tawar. Energi panas untuk proses destilasi dapat berasal dari matahari yang dikenal dengan energi surya. Sebenarnya energi surya merupakan sumber energi yang sangat potensial, murah dan gratis. Penelitian ini bertujuan untuk melihat dan mengetahui unjuk kerja yang dihasilkan alat destilasi surya yang menggunakan penutup kolektor dua kemiringan. Hasil pengujian menunjukkan alat destilasi surya dapat menghasilkan garam sebanyak 2.600 gram dan air tawar sebanyak 2.012 mili liter per hari dengan intensitas rata-rata 451 W/m2

Abstract

Due to the near-universal presence of air conditioning systems in Indonesian buildings, the development of solar-powered air conditioning units has accelerated recently. The tropical country of Indonesia benefits from year-round sunlight. In this study, a photovoltaic (PV) system that includes a battery, a photovoltaic system composed of PV panels, a solar charger, a DC power controller/inverter, and a battery is combined with a solar-powered air conditioning system to analyze its design and performance. In locations without electricity, this air conditioning technology is usable. Obtaining approximately 1 ton of refrigeration (3.52 kW) through the first step of this research's cooling load calculation for the space to be conditioned. An estimated photovoltaic (PV) system that includes all the required connections has been constructed based on this cooling load. Temperature measurements at crucial cycle locations, including the compressor's inlet and outlet as well as the evaporator and condenser, have been made using a data logging system. All day long, measurements were made of the system's input power and coefficient of performance (COP) under Indonesia's climate. The results are compared to the performance of traditional systems and the coefficient of performance for the system ranges from 2.9 to 8.5. for the system and these results are compared with the performance of conventional systems
