Mechanics, 2011 An original rotary heat pump suggested by the authors is described in the presented paper. All thermodynamic processes of working fluid (evaporation – compression – condensation) based on the principle of heat pipe are provided in one volume of mushroom form closed vessel. The transportation of external heat flows is combined in the unit as well.
