Abstract (en)
The device has a closed circuit (10) provided with a compression pump (12) for fluid i.e. water, in liquid form. A heat exchanger (18) i.e. evaporator, is swept by a hot source (24) for evaporation of the fluid. An expansion machine i.e. expander, is utilized for expanding the fluid in vapor form. A cooling exchanger (36) or condenser is swept by a cold source (F) for condensation of the working fluid. A fluid collection tank (52) is utilized for draining the circuit. The tank comprises a heating system (66) for heating the liquid contained in the tank. The tank is an insulated tank and an expansible tank. An independent claim is also included for a method for controlling working fluid with low freezing point circulating in a closed circuit operating according to a Rankine cycle.
