| Özet |
| This study presents the exergetic investigation of an automotive air conditioning (AAC) system with the refrigerant R1234yf experimentally. The air-conditioning system is based on the conventional mechanical compression refrigeration cycle. An internal heat exchanger (IHX) has been added to the system in order to provide performance enhancement. The influence of the IHX investigated at different compressor speeds and air stream temperatures. Experimental measurements were collected by using a data-acquisition system, and the results were obtained by performing exergetic analysis. The exergy destruction, exergy efficiency and the total exergy destruction per cooling capacity were calculated. The analysis results were compared with a baseline system which operates with the refrigerant R134a. Furthermore, an empirical correlation was proposed for the determination of the total exergy destruction per cooling capacity for various compressor speeds for evaluating the system performance without doing further experiments. As a result, the exergetic efficiency of the system was improved by introducing IHX to the system. Moreover, it was observed that the temperature rise in the air stream decreased the exergy efficiency and increased the total exergy destruction per cooling capacity. |
