Abstract

Energy systems such as district heating systems require that different forms of energy can easily be converted into one another. A heat pump is a device which is able to achieve this, by converting electric energy into thermal energy. This is executed by means of the heat pump cycle, containing a compressor, condenser, valve and evaporator. In this thesis, the physics behind the cycle and its components are investigated, and written out in a dynamical model. The dynamical model couples a low temperature heat source to a district heating network via the heat pump cycle. It describes the dynamic behavior of the heat pump, based on the pressure of the refrigerant in the different components. One the one hand, this approach simplifies complex state-of-the-art physical models that are incompatible to couple in district heating context. On the other hand, it provides advanced physical detail in comparison to simplified heat pump models that were already developed for district-heating cases. Eventually, the physics-based modeling approach is verified through simulation, and design of a state feedback controller after linearization
