Energetische Evaluierung von Kältespeichern und Abwärmenutzung für Kühl‐ und Gefrieranwendungen

A thermodynamic analysis of cold storage systems and waste heat usage for refrigeration and freezing applications is presented. The focus is set mainly on the energetic efficiency of the systems. The environment is considered as an infinite heat sink to which the heat from the refrigeration compartment can be transported directly. Five different concepts are presented and evaluated based on the annual electric energy and primary energy demand.
