Temperature glide matching in a zeotropic mixture heat pump [PDF]
The use of zeotropic mixtures in heat pumps should lead to a reduction of the exergy losses within the heat exchangers due to the temperature glide (TG) and thus to an improvement of the entire process. In a previous publication (ECOS 2016), the coefficient of performance (COP) as a function of evaporation / condensation temperature, compressor ...

Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...
