Mesures et simulation de la mise en route et de la mise à l'arrêt des pompes à chaleur.

Measurement and simulation of start-up and shut down of heat pumps.

Auteurs : UHLMANN M., BERTSCH S. S.

Résumé

The reduction in heating capacity due to on/off cycling of a heat pump can lead to a performance reduction of 5-30%. In order to get a better understanding of the important parameters to improve the performance of heat pumps, a physics based model is being developed and validated with according measurements. The aim of the model is to achieve a stable and accurate solver with only few empirical tuning parameters. While most "dynamic" models in the literature are actually steady state models calculated for different operating conditions throughout the year, the aim of this project is to characterize the unsteady behaviour during the first minutes of runtime and shutdown. Start-up and shut down measurements of brine and air source heat pumps are presented, as well as a preliminary model for the simulation routines.
