This study proposes an absorption-compression cascade refrigeration cycle. The cycle consists of a high-temperature stage combined absorption-compression refrigeration cycle
which is driven by the waste heat of the internal combustion engine
and a low-temperature stage CO2 subcritical compression refrigeration cycle
which is driven by power. The performances of different refrigerant pairs in the cycle are compared
and the influence of key parameters on the performance of the cycle is further discussed. Finally
an economic analysis is performed. The results show that under the same condensation temperature of 40 °C and evaporation temperature of ?35 °C
R124-DMAC/R744 exhibits excellent performance with a coefficient of performance of 2.864. It is an ideal working pair
and the annual total cost of the system is 15 150.14 USD.
