PRODUCTION OF ELECTRICITY BY EXPANSION AND CONTRACTION IN VOLUME OF SOLVENT USING SOLAR ENERGY

摘要

An environment friendly process for conversion of solar energy to electrical energy is provided. The system includes solar collectors having cardinal points to collect the solar energy provided with turbine. The difference between boiling point of heat storage liquid/ ionic liquid and solvent is stored using parabolic solar collectors and is later transferred from heat storage liquid to solvent, leading to change in form of solvent from liquid to vapour inside heat exchanger. This increases the volume and pressure causing the rotation of turbine for generation of electricity. The solvent steam is later condensed to liquid form using condenser leading to decrease in its volume and pressure. The pressure differential between inter-connected equipment from heat exchanger to turbine to condenser, in the closed system, causes movement of vapour from high pressure to low pressure leading to mechanical movement of turbine and generation of electricity. Large amount of heat transfer liquid can be heated using parabolic solar collector during whole day and can be stored for 24 X 7 uses inside insulated tank. And hence, electricity production can be run 24 X 7.
