ORC HEAT ENGINE

摘要

An ORC heat engine including a working fluid circuit having an evaporator for heating and evaporating a working fluid, a condenser for cooling and condensing the working fluid, and a positive displacement expander-generator having an inlet in fluid communication with the evaporator and an outlet in fluid communication with the condenser. The ORC heat engine further includes a control system coupled to the positive displacement expander-generator having a switch and driving means, the switch being switchable between a first state and a second state, wherein in the first state the switch is coupled to the driving means, and the positive displacement expander-generator is drivable by the driving means, and in the second state the switch is not coupled to the driving means or the driving means is switched off, and the positive displacement expander-generator is not drivable by the driving means.
