Improving the Traditional Heat Pump System Control through Prediction of Daily Solar Radiation
It's sunny outside: does your heat pump know? Traditional control approaches for heat pump systems in residential buildings are based on the "heating curve" setting, where the supply temperature to the heating (or cooling) distribution system is defined as a function of the outdoor temperature. If the outdoor temperature is the only control input available, the heat pump system cannot take into account important additional inputs, like solar radiation, that can substantially vary on a daily basis throughout the year and negatively affect the indoor comfort and the energy-saving possibilities.
