Abstract: The energy transition will not succeed without a fundamental transformation of the building heat supply. Preliminary studies have shown that improving the thermal insulation of buildings will not yield sufficient reduction in energy demand and greenhouse gas emissions. New efficient heat supply systems are needed to enhance the use of renewable energy in the building sector. Electrically driven heat pumps are promoted for the heating sector, currently dominated by fossil fired boilers. Aiming at best adaptation to the fluctuating availability of electricity from renewable sources, grid-serving operation of heat pumps is required, allowing temporal decoupling of electricity consumption and heat demand of buildings. As an alternative to electrical energy storage, heat pumps with integrated latent heat storage can offer the desired flexibility. To design these systems and to describe the interaction of the individual components, a simulation model has been created using the Engineering Equation Solver (EES) software. The model has then been validated by comparison to measurement data obtained by laboratory tests of a pilot plant.
