Summary

The paper is concerned with the study of the application of capacity control devices on heat pump reciprocating compressors. Five typical control systems have been studied: variable speed, variable clearance volume, by-pass of the discharge gas, throttling of the suction gas and suction valve cut-off. A simulation model was developed for the analysis. The heating COP and the compressor discharge temperature were chosen for the comparison between these five mechanisms. Model predictions revealed that variable speed and variable clearance volume should present the best results. Worst performances went to suction throttling and discharge gas by-passing, both of which present highly irreversible processes.
