“…The combination of solar energy and heatpumps have been studied as well in other literature such as (e.g., [2,5,7,8,11,12,15,16]. In all of these cases the source of the heatpump was not air but ground or water.…”

In this paper agent-based simulation is used to analyse the efficiency of domestic heating based on a heatpump together with photovoltaic (PV) solar energy production. A simulation model for the cost (in terms of required kWh per day) of a heating agent based on a heatpump over a year is used, in addition to a simulation model for the yields of a PV production agent estimating the produced solar energy (in kWh per day). In particular, for the heating agent it is analysed how its performance depends on the outdoor temperature, and for the PV-installation agent how the yields depend on irradiation. Based on empirical temperature and irradiation data over a year it is found out which fraction of the energy required per year for heating can be covered by the yields of the PV installation.

“…Another extension of the presented approach is to allow for partial allocation, in which can the allocation is not exclusive, but also have the form of allocation both agents at the same time, but each for a certain fraction of the heating task. Finally, another interesting extension is to analyse the current approach when it is combined with electricity production by solar panels (e.g., [2,8,10,11,15]). …”

Abstract. In this paper a multi-agent model for a domestic heating task is introduced and analysed. The model includes two alternative heating agents (for gas-based heating and for heatpump-based heating), and a third allocation agent which determines the most economic allocation of the heating task to these heating agents over the days in a year. For allocation decisions it is analysed how the performance of a heatpump depends on the outdoor temperature. One method discussed is a what-if analysis method using agent-based simulation, another method is by mathematical analysis to derive more precise knowledge about the most optimal allocation choice. These methods can be used by the allocation agent to determine in a dynamic, adaptive manner per day a most economic allocation, depending on the (predicted) outdoor temperature.

“…It is better to drive the ABS chiller by a renewable energy or waste heat source, for instance, a solar thermal source. The final temperature of the processed CO 2 can be reduced to below 30 • C. Furthermore, the fitting equation [19,25] shows that the optimal discharge pressure of the compressor is directly related to the outlet temperature of the gas cooler, when the system operates in a steady state. Thus, it is possible to decrease the discharge pressure below 9 MPa by the assistedcooling input and in turn reduce the electricity consumption of the compressor.…”
