This research paper entitled Investigation of Organic Rankine Cycle using different working fluids for conversion of low grade heat sources, is studied in Final Year Project I and Final Year Project II. This paper is reviewed on type of Rankine cycles that produces electrical power of heat sources, including conventional Rankine cycle and especially organic Rankine cycle. Water as the common working fluid for Rankine cycle when the heat input is from high grade heat sources, example coal and fuel. High molecular weight working fluids example, R22, R134a and R141b are ideal for Organic Rankine Cycle, this is because is boiling point of those working fluids are relatively very smaller compared to water. Besides that, ORC uses low grade heat sources like, solar and waste heat energy. The main purpose of this research project is to identify suitable organic working fluid which gives better work net, back work ratio and efficiency.
