Summary

The measurement of the kinematics of reciprocating compressors, such as position, speed and acceleration, is an important part of a wide range of tests. Examples of these tests are the determination of the indicator diagram, which depends on the measurement of the piston position; the determination of the Coefficient of Performance (COP), which requires the measurement of angular speed; and friction loss experiments, which require the rotational speed and the deceleration of the compressor. Due to their importance for research and development of reciprocating compressors, this paper presents a review of the kinematic measuring methods for reciprocating compressors. Additionally, a test rig was designed to perform static and dynamic measurements of the piston and crankshaft kinematics. The applicability of a linear variable inductance transducer in a reciprocating compressor was evaluated by comparing its response to the measurements obtained from an encoder.
