Bivalent Heat Pump Plant serving a Multi-Family Dwelling - Quantification of the Impact of Different Control Strategies and Parameterisations

This article shows the effects of different control strategies and controller parameterisations on the KPIs energy purchase costs and non-renewable primary energy consumption for a bivalent air-to-water heat pump plant. This demonstrates the importance of system automation and the commissioning phase for energy-efficient operation. The study showed that KPIs were up to 39% exaggerated due to unfavourable parameterisation. If the optimum parameterisation cannot be determined on the basis of preliminary technical considerations, simulation-based variant studies are a suitable method for identifying a sound parameterisation. This is exemplified for some parameters in this article.
