Modeling and Testing of an Automobile AC Scroll Compressor, Part I: Model Development
نویسندگان
چکیده
This paper presents the details of an overall simulation model that predicts the performance of an automobile air conditioning scroll compressor. Using the overall model, the compressor performance and discharge temperature can be predicted at specific operating conditions. The model will be used in the future to optimize the design of automobile air conditioning scroll compressors. The model was developed based on an investigation of the geometric characteristic of an existing compressor, the modeling of the compression process, and an efficiency analysis. The pre-compression at the end of the suction process and re-compression at the discharge angle are taken into account in the process model. Tangential leakage and radial leakage during the compression process are investigated within the efficiency analysis. The influence of superheat and heat transfer during the compression process on performance are also taken into account within the efficiency analysis.
