Abstract

The focus of this study is an experiment and simulation of an Organic Rankine Cycle (ORC) system to produce electricity. The experimental equipment consisted of four main components: fluid pumps (for refrigerant and water); a condenser as a heat exchanger to condense the working fluid; an evaporator (boiler) as a heat exchanger to evaporate the refrigerant; and an expander (turbine) as a driver to produce electricity. The expander was a modification of a scroll air conditioning (AC) compressor, with a capacity of 1-3 kilowatts and connected to the generator to produce electricity in line with the design estimate. Furthermore, based on the application of the ORC experiment in the form of a small-scale power plant, a pre-determined temperature setting was set for the heat source, ranging between 80 and 100°C. The working fluid used in the study was R-134a. Optimum power estimation was obtained by processing the experimental result data using a software cycle tempo simulation that measured several electrical power outputs between 1.76 and 2.74 kilowatts.
