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

Abstract

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.
