THERMODYNAMIC CHARACTERISTICS OF RECIPROCATING COMPRESSORS FOR MOTOR VEHICLES

Abstract

Validation of thermodynamic characteristics of reciprocating compressors for motor vehicles is performed on test bench which allows measurement of cylinder pressure of compressor depending on the angular position of the compressor crankshaft. This paper presents the characteristics of the test bench and measurement results of compressor's indicator diagram. The measurement results are compared to simulation results and results obtained by other authors from measurement on similar compressors. Good agreement between the results of measurements and the results of simulation and literature data are obtained.
