Evaluation de la performance d'une pompe à chaleur au CO2 transcritique utilisant un compresseur à piston.

Performance assessment of a transcritical CO2 heat pump using a reciprocating compressor.

Auteurs : IBRAHIM A. G., FLEMING J. S.

Résumé

A performance assessment of a transcritical CO2 heat pump designed for residential applications and using a hermetic reciprocating compressor is presented. A mathematical model of a reciprocating compressor suitable for heating/cooling cycles in which the working fluid is carbon dioxide is described. The performance of the compressor as predicted by the model is examined over a range of operating conditions. The compressor model is incorporated into a heating/cooling cycle analysis and used to examine the heating/cooling performance over a range of evaporator and gas cooler pressures. The influence of compressor speed and internal leakage on cycle efficiency is examined quantitatively and discussed.
