Abstract


Hot water is required for bathing and cleaning of utensils in the morning and evening hours in Indian homes. People in rural areas use fossil fuels, cooking gas and rarely electricity for hot water production. Present day solar collectors cannot help in instant hot water generation. A system involving a parabolic trough, an evacuated tube and Therminol D-12 oil is developed and studied for instant hot water generation. The developed system works satisfactorily during low incident solar radiation. Experiments on the developed new system show that Therminol D-12 helps to generate hot water at a temperature of 60°C within 10 minutes of time with low solar radiation.
