Une nouvelle approche d'optimisation de pompe à chaleur tenant compte du couplage entre les réservoirs thermiques et le cycle.

Author(s) : FEIDT M., COSTEA M.

Type of article: IJR article

Summary

The available literature on heat pumps shows that thermodynamic models lead to minimization of energy expense, very often in endoreversible configurations, sometimes irreversibles. The present paper purpose is to revisit and complete the heat pumps irreversible model by adding the coupling constraint between the cycle and the thermal reservoirs assumed to be thermostats. This constraint is in fact an essential condition for the cycle existence, practically always ignored. This modeling leads to a set of new results, including new expressions for the COP corresponding to minimum energy expense. The fundamental consequences of this new approach also show the limits of the equipartition theorem of heat exchange area, as well as of the entropy minimization method (EGM).
