Derivation of heat transfer equations for a closed solar desalination pond to predict the produced mass of potable water

摘要

In many developing countries, access to clean and drinkable water is a major necessity. The sweetening of saline water in these areas is used to provide water for different requirements. The solar distillation is based on solar technology. The aim of this study is to calculate the efficiency of a solar desalination pond to produce freshwater. To achieve the purpose of research and validation of the obtained mathematical results, the experimental measurements are used. The conservation law of energy is considered and mathematics is applied to predict the required heat for the evaporation process. Finally, a new mass transfer equation on the basis of experimental data is introduced to predict the efficiency of solar desalination pond performance. The obtained results show the maximum deviation between the experimental and theoretical condensation rates. In October, the deviation is 4.93%, approximately, whereas, this deviation for June is 1.75%, approximately. So, the mathematical equation can predict the efficiency of a solar desalination pond precisely.
