•An innovative solar energy storage concept for providing refrigeration is proposed.•A possible form of load management for photovoltaic energy.•Phase change materials are used as low-temperature thermal energy storage.•Parameter study to evaluate the energetic efficiency of the new storage concept.•Economic evaluation compares the presented storage concept with battery storage.
In this paper a thermodynamic analysis of a concept approach based on a possible form of load management for photovoltaic energy is presented. By using the surplus electricity for driving a compression chiller it is possible to load a low temperature thermal storage. This cold storage can be used to cover the cooling demand of domestic refrigerator and freezers. A parameter study was performed to evaluate the energetic efficiency for this system in a single family home. A short economic evaluation compares the concept to a system without storage and to a system with battery storage.
