The investigation of using phase change material for solar pond insulation

Solar ponds are systems that store solar energy in salt water as heat energy. In order to for a long time pond, the insulation should be done well. this study, effect of phase change materials was investigated improve pond and longer time. The melting temperature is key parameter selection materials. distribution examined with temperatures range average ?10?C were selected. Three different used walls insulation. enthalpy changes system calculated numerically year. storage ratio determined by using obtained radiation data. Consequently, glass-wool maximum 20.95% July minimum 7.92% January. which paraffin C18, capric acid 44 32.22%, 34.85%, 47.81% December, respectively. It observed appropriate provided ponds.
