Experimental Study of the Recovery of Low Heat Using the Organic Rankine Cycle

Abstract

Nowadays, Organic Rankine Cycle (ORC) poses a good solution for waste heat recovery. In this research, we have chosen the appropriate working fluid for ORC to be tested and worked out among a range of wet and isentropic working fluids available to us in the domestic market. A test bench for the ORC has been developed to recover heat at temperature $85^{\circ}\mathrm{C}$ using R141b, which resulted in a thermal efficiency about 2.24% due to the low efficiency of the equipment. In spite of the low thermal efficiency of ORC, it is effective in heat recovery processes.
