Utilizing Excess Heat from a Supermarket Refrigeration System in a District Heating Grid

摘要

In light of the continuous requirements for increased energy efficiency, utilisation of renewable and surplus sources, more and more new flexible sources are utilized in the smart energy system. This article is focusing on utilization of excess heat from a supermarket refrigeration system for the district heating system. Furthermore, introduction of related electric and thermal energy flexibility is addressed, within a smart energy system development perspective, where the 4th generation district heating concept is an important part of the envisioned energy infrastructure.
