Abstract

A MATLAB code has been developed based on REFPROP software for the design and analysis of Organic Rankine Cycle (ORC) systems. A small-scale ORC system using a scroll expander was designed using this code, and the effects of varying the expander pressure ratio, cycle maximum temperature, and presence of a recuperator were investigated. It was discovered that the fixed pressure ratio of a positive displacement device has a significant effect on the behaviour of the system although any losses incurred by not fully utilising the waste heat due to small expansion ratios can be mitigated by the use of a recuperator. The results will be presented and discussed in detail.
