| description | To meet the need for energy efficiency improvement and substitution of traditional refrigerants in the field of supermarket refrigeration, a supermarket booster refrigeration system using the eco-friendly zeotropic refrigerant CO2/R1234yf is proposed in this study. A thermodynamic model is established and compared with that of a pure CO2 booster refrigeration system. The results show that the maximum COP (1.40) of the system using CO2/R1234yf was obtained under the optimal CO2 mass fraction (0.94) and discharge pressure (8.81 MPa). The COP of the CO2/R1234yf booster refrigeration system was significantly improved compared with the pure CO2 system, which increased by 7.25% when the ambient temperature was 35 ℃. The APF improvement of the CO2/R1234yf booster system was 2.68%–4.72%. The APF increased with an increase in the latitude of typical cities. The exergy efficiency of the CO2/R1234yf booster system first increased and then decreased with increasing CO2 mass fraction. The CO2/R1234yf booster refrigeration system exhibited the highest exergy efficiency (0.18) when the CO2 mass fraction was 0.95, which was 4.62% higher than that of the CO2 system. |
