Heat knowledge: Efficiently using waste heat and solar energy in hotels

Hotels generate usable heat sources in many places—for example, from air conditioning and refrigeration systems or PVT modules. However, this heat is often generated at a temperature that is too low to be used directly for heating or hot water. The eXergiemaschine can efficiently raise the temperature of such heat sources to a higher level while simultaneously ensuring a cool return flow. In this in-depth technical article, you’ll learn how waste heat and solar heat can be effectively utilized in hotels, what additional efficiency benefits this brings for refrigeration and PVT systems, and how this can help reduce reliance on fossil fuels.
