Energy converters
Basic concepts of energy converters

An energy converter (Σ _c ) is a special (thermodynamic) system capable of transferring energy from one system to another (tanks or any other system) by changing the type of energy. This energy conversion must be able to continue (at least theoretically) through cyclic operation of the device. A converter is considered perfect when it performs reversible cycles, and heat exchanges with reservoirs are also reversible.

In the thermodynamic sense of the term, a reservoir (source or sink) of energy of a certain type is a particular system whose intensive variable (In) remains constant and uniform throughout the system (which is then in a state of equilibrium) when it...
