摘要：
This study analyses off-design performance of combined cooling and power cycle with CO2-based mixture mounted in refrigeration truck. Engine operating conditions is classified first according to the parameters of road conditions; then, thermodynamic model and off-design model are established. Results show that the best CO2 mass fractions are different for various engine operating points; on the other hand, for the comprehensive performance of the whole road condition, the best designed CO2 mass fractions are equal when considering thermodynamic design and off-design operation. © 2023 Science Press.
