| Summary: | The thermodynamic model to analyze the scroll compressor refrigeration with twice-vapor injection system has been set up and the calculation program is designed. The two suitable middle pressures are calculated, and the recommended empirical formulas are provided to calculate most suitable two stage middle pressure. Based on one scroll compressor, the method of how to make injection hole is developed. At last, the system performance is calculated, and the simulation results demonstrate that the cooling COP of new system with twice-vapor injection can be about 2.8% and 12.4% higher than that of the one hole vapor injection system and normal single stage system, the discharge temperature can decrease 3 - 4 ℃. |
