ASSESSMENT OF HIGH TEMPERATURE HEAT PUMP LAYOUTS EQUIPPED WITH A BLADELESS TURBOEXPANDER

pursuing the ambitious targets of electrification of industrial processes and thermal generation via renewable power. This work evaluates the optimal thermodynamic performance features of heat pump cycles comparing conventional layouts with those adopting a Tesla turboexpander, for recovering pressure drop in high temperature applications. The paper focuses on n-pentane (R601), a natural refrigerant, being a favorable substitute of synthetic refrigerants thanks to
