Low-grade waste heat
WebLets say that we are using low grade heat with a temperature gradient to a heat sink of 60 degrees, we might get 7 to 15% upper total efficiency. Without turning this heat to electricity, which easily gives us high grade head, but at the added expense of the electrical system, that is what I am looking to avoid. WebIn this paper, the most promising methods and technologies for recovering data center low-grade waste heat in an effective and economically reasonable way are identified and discussed. A number of currently available and developmental low-grade waste heat recovery techniques including district/plant/water heating, absorption cooling, ...
