Abstract: The invention relates to a thermodynamic cycle apparatus, comprising: a working medium; an evaporator for evaporating the working medium; an expansion machine for generating mechanical energy while expanding the evaporated working medium; a condenser for condensing the working medium, and a pump for pumping the condensed working medium to the condenser, wherein the geometrical arrangement of the evaporator is selected such that, prior to starting the pump, the condensed working medium can flow from the condenser to the evaporator by force of gravity and the working medium can circulate in a closed circuit via the evaporator and the condenser, whereby in particular a predetermined head height of the liquid working medium can be provided at the pump. The invention additionally relates to a method of starting the thermodynamic cycle apparatus according to the present invention, the method comprising the following steps: applying heat to the evaporator and evaporating the working medium in the evaporator, whereby working medium is caused to flow to the condenser; condensing the working medium in the condenser; starting the pump when a predetermined head height of the working medium at the pump is reached or exceeded.
