- Abstract:
- A thermodynamic model is established to make a theoretical analysis on conventional compressionrefrigeration systems ( CRS ),throttling losses under various operating conditions are simulated with MatlabR2010a.R134a is chosen as refrigerant in the model and its thermo-physical properties are obtained fromREFPROP 9.0.The results show that:1. throttling losses in CRS accounts for 13 to 31.9 of compressor pow-er; 2.throttling losses of double temperature CRS are about 50% higher than that of the single temperatureCRS; 3.throtling losses change with operating conditions. According to the characteristics of CRS, three com-monly used ways to recover throttling losses are analyzed. COP of C/ERS is simulated under various operatingconditions and compared with the simply recover throttling losses scheme,the results verify the feasibility of u-sing ejector in CRS.
