Single Slope Modification Design for Experimental Study of Solar Desalination System Performance

Abstract

Fresh water from the desalination process is expected to be commercially produced in large quantities for world consumption needs. In this paper, experimental testing is carried out to obtain the overall characteristics of the desalination device to suit the placement of the test area. The single slope passive desalination tool model with a slope of 35^o is still used as the object being tested because of its low cost and environmentally friendly use of solar energy. It is hoped that the performance improvement can be made after obtaining the characteristics of the desalination tool as a whole. It is obtained that the heat energy absorbed reaches 0.31 kWh with a solar intensity of 534.40 W/m² at the same time. The production of fresh water during the test always follows the brightness and solar intensity. Experimentally obtained the allergy from the desalination device of 0.53 kW/m² with an energy efficiency of 58.4% with the highest amount of hourly fresh water production of 2.6 kg.
