The design of the swash plate compressor is complex so that it requires considerable contributions from different fields of engineering viz. engineering mechanics, heat transfer and fluid dynamics. An estimate of compressor performance through an analytical/ mathematical model at the early stages of design and development serves as a useful tool for the designer. The input power, refrigerant mass flow rate, compression ratio and volumetric efficiency are important parameters to characterise the compressor performance. This paper presents an analytical/mathematical model for a 10-cylinder swash plate compressor with the emphasis on predicting its performance in terms of shaft torque and mass flow rate for a given rpm. A kinematic model is developed to obtain the piston displacement as an explicit function of angle of rotation of the swash plate. The model of piston and swash plate dynamics is developed then by analysing the interactions between forces and moments. The compression process model is formulated to determine the temperature and pressure inside the cylinder during one revolution of the swash plate along with the total mass flow rate in and out of the compressor. A time-varying model for the compressor is developed by combining the above three sub-models. Some experimental validation comparing predicted and measured drive torque has been done to verify the analytical/ mathematical model The predicted torque is in close agreement with the measured value. dc.description.peerreviewed Yes dc.publisher American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) dc.publisher.uri https://www.ashrae.org/technical-resources/ashrae-transactions dc.relation.ispartofconferencename 2020 Winter Conference of the American Society of Heating, Refrigerating and Air-Conditioning Engineers dc.relation.ispartofconferencetitle ASHRAE Transactions dc.relation.ispartofdatefrom 2020-02-01 dc.relation.ispartofdateto 2020-02-05 dc.relation.ispartoflocation Orlando, USA dc.relation.ispartofpagefrom 351 dc.relation.ispartofpageto 359 dc.relation.ispartofvolume 126 dc.subject.fieldofresearch Mechanical Engineering dc.subject.fieldofresearch Microelectromechanical Systems (MEMS) dc.subject.fieldofresearch Nanotechnology dc.subject.fieldofresearchcode 0913 dc.subject.fieldofresearchcode 091306 dc.subject.fieldofresearchcode 1007 dc.title Analytical model for a 10 cylinder swash plate electric compressor dc.type Conference output dc.type.description E1 - Conferences dcterms.bibliographicCitation Arqam, M; Dao, DV; Jahangiri, A; Yan, H; Mitchell, M; Woodfield, PL, Analytical model for a 10 cylinder swash plate electric compressor, ASHRAE Transactions, 2020, 126, pp. 351-359 dc.date.updated 2021-02-11T01:27:13Z dc.description.version Version of Record (VoR) gro.rights.copyright © 2020.
