Summary

In this study, a working fluid selection was conducted for an organic Rankine cycle (ORC). The ORC used in this study adopted the district heat source, which is rarely utilized in the cooling season. The power and heat generated from the ORC was used for a liquid desiccant system. Considering the environmental impact, nPentane, R1233zd(E), and Novec649 were utilized and compared with R245fa, which is one of the hydrofluorocarbons. Thermodynamic analyses of all the fluids were conducted, and Novec649 was selected owing to the high total net power and heat output. The testbed for ORC driven liquid desiccant system was developed using Novec649, and it can provide the desiccant solution at over 50°C to enter the regenerator of liquid desiccant system without requiring an auxiliary heater.
