This work explains the set-up of a Hardware-in-the-Loop experiment to test an energy flexible heat pump controller under realistic conditions. The developed simple, low-cost model-predictive control algorithm can easily be integrated with a traditional heat pump controller.enThermische Systeme und Gebäudetechnikheat pumpenergieeffizientes GebäudeGebäudesystemtechnik621697Model-Predictive Control for Testing Energy Flexible Heat Pump Operation within a Hardware-in-the-Loop Settingconference paper
