Dynamic model of a hermetic reciprocating compressor in on-off cycling operation (Abbreviation: Compressor dynamic model)

摘要

This paper presents a dynamic model of a hermetic reciprocating compressor in on-off cycling operation. The proposed model is detailed enough to account for the important phenomena influencing the suction and discharge mass flow rates and the electrical power drawn by the compressor, but simple enough to be usable for different reciprocating compressor designs with readily available data from manufacturers. The experimental validation of the model under steady-state and transient conditions in both heating and cooling modes confirms the good performance of the model.
