| Summary: | Addressing water scarcity issues in rural area by solar distillation method is commonly used because of its simple process, fabrication and low energy cost. Low productivity of a conventional solar still encourages many modifications and novel design including pre-heating of inlet water to solar distillation system for higher water yield. This dissertation studies the enhanced performance of solar distillation system with multiple linear facet concentrator. The maximum inlet water temperature of the solar distillation system as pre-heated by multiple linear facet concentrator is up to 80.05oC under the flow rate of 5LPH. It is concluded that the flow rate 5LPH has the highest water yield rate under the inlet water temperature of 70oC to 80oC. The highest water yield efficiency is found to be 45.59% at the flow rate of 3LPH. A mathematical model of the system is developed to simulate the solar distillation system which allows study of the system without on-site experiment, hence reduce the burden and cost of conducting experiment. Under steady state condition, the highest fresh water productivity of 10.45kg for 6 hours constant sun exposure is achieved at the flow rate 5LPH under ambient temperature of 30oC and solar irradiance of 800W/m2 . |
