Diagrammes de rendement frigorifique d'une pompe à chaleur à hydride de métal entraînée par compresseur.

Cooling power efficiency diagrams for a compressor-driven metal hydride heat pump.

Résumé

Finite-time thermodynamics is used to develop cooling power/efficiency diagrams for a compressor-driven metal hydride refrigerator. The two most important parameters, resistance to heat transfer between the reactors and the reservoirs and the thermal capacities of the system, are included in the analysis in a detailed and realistic way. A simple quasi-steady-state model is used to investigate this effect and its relation to cooling power and efficiency of the system. Another interesting aspect is that increased finning outside the reactors reduces the efficiency, a trade-off exists between cooling power and COP. The effect of compression ratio on the system performance is also investigated.
