Abstract

In this paper, an organic Rankine cycle driven vapor compression refrigeration (ORC-VCR) system for heavy-duty trucks’ cab and sleeper air conditioning using the waste heat in engine coolant is analyzed. R245fa and R134a are, respectively, selected as working fluids for the power and cooling cycles. Assuming 5.0 kW cooling capacity needed, the study shows that under the typical working conditions, the overall coefficient of performance (COP) and heat requirement of the ORC-VCR system are about 0.224 and 22.343 kW, respectively. The effects of operating parameters on the system performance are also discussed.
