Use of the Lorenz Cycle in Heat Pumps

The use of the Lorenz cycle together with the inverse Carnot cycle increases the conversion efficiency of a heat pump by 25–30%. The Lorenz cycle may be implemented either through the use of nonazeatropic substances or by multistage circuits. The Lorenz cycle is more efficient at low temperature differences of the working substances. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
