<p>The present invention relates to an arrangement and a method for converting thermal energy to mechanical energy. The arrangement comprises a line circuit (3), circulation means (4) for circulating a zeotropic refrigerant mixture in the line circuit (3), an evaporator (6) in which the refrigerant mixture is intended to be vaporised by a heat source (7), a turbine (9) adapted to being driven by the vaporised refrigerant mixture, and a condenser (12) in which the refrigerant mixture is intended to be cooled so that it condenses. The arrangement comprises control means adapted to assessing whether the refrigerant mixture does not become fully vaporised in the evaporator (6) and, when such is the case, to leading the incompletely vaporised refrigerant mixture leaving the evaporator to a separating device (14) in which the portion of the refrigerant mixture which is in liquid form is separated from the portion of the refrigerant mixture which is in gaseous form, after which only the gaseous portion of the refrigerant mixture proceeds towards the turbine in the line circuit (3).</p> |
