Fluid Mechanical Modelling of the Scroll Compressor
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Mathematical Institute Eprints Archive Fluid mechanical modelling of the scroll compressor by Peter Howell University of Oxford Mathematical Institute, 24{29 St Giles', Oxford OX1 3LB, UK Preface. This case-study concerns the flow of gas in a so-called Scroll Compressor. In this device a number of chambers of gas at different temperatures and pressures are separated by narrow channels through which leakage can occur. Using compressible lubrication theory, an estimate for the leakage rate is found in terms of the material properties of the gas and the geometry of the compressor. Thus a simple functional is obtained which allows the efficiency of different compressor designs to be compared. Next we derive a set of ordinary differential equations for the temperature and pressure in each chamber; the coupling between them arises from the leakage. The numerical solution of these equations allows a realistic simulation of a working compressor, and suggests some interesting possibilities for future designs. This problem arose at the 32nd European Study Group with Industry held in September 1998 at the Technical University of Denmark | the first ever to be held outside the United Kingdom. It was presented by Stig Helmer Jørgensen from DANFOSS, which is Denmark's largest industrial group and specialises in controls for refrigeration and heating. The Danish Study Group was a great success and is expected to be repeated annually henceforth. The feedback from DANFOSS has also been encouraging and hopefully this represents the start of a long-term collaboration. -

Exergy Analysis and Thermodynamic Model for Reciprocating and Scroll Compressors Used in an Air Conditioning Packaged Unit
Journal of Engineering and Development, Vol. 18, No.5, September 2014, ISSN 1813- 7822 Exergy Analysis and Thermodynamic Model for Reciprocating and Scroll Compressors Used in an Air Conditioning Packaged Unit Prof. Dr. Sabah Tarik Ahmad Prof. Dr. Wahid S. Mohammad Lecturer. Dr. Louay Abd-Alazez Mahdi Machine and Equipment department., University of Technology Abstract : An exergical thermodynamic model was used to analyze and optimize reciprocating and scroll compressors of an air condition packaged unit. The experimental work was carried out using 3.0 TR packaged unit manufactured by Carrier Company. The experimental and the analysis show that the exergy dissipative due to friction losses in bearings, suction and discharge valves and the transformation of power are larger than the heat losses. The exergy efficiency for the compressor was varying between (60-68) %. The scroll compressor was found to be better than the reciprocating compressor at an environmental temperature of 35℃ due to its low total losses which is 10% less than the reciprocating compressor ones . The heat losses percentages were 3% for scroll and 2% for the reciprocating of the total power input. The thermodynamic model has shown to be reliable in dealing with a change in the environmental temperatures and such system components and size.
