Storing surplus solar energy in low temperature thermal storage for refrigeration applications
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. (C) 2016 Elsevier B.V. All rights reserved.
