Experimental Study on an Inverter-Driven Scroll Compressor with an Injection System
نویسندگان
چکیده
For an inverter-driven compressor, the discharge temperature increased with a rise of frequency. Therefore, it is necessary to control the discharge temperature at high frequencies in order to obtain system reliability and efficiency. This paper describes the effects of an injection system on the perfonnance of an inverter-driven scroll compressor. As results of the present work, the refrigerant discharge temperature for the injection system dropped approximately 10~20°C as compared to those for the non-injection system. The COP of the compressor was improved approximately 0.8~9.3% at high frequencies (75, 90, and 105Hz). The injection port at 180° showed a lower discharge temperature and a higher COP as compared to those at 90°.
