The aim of the paper is to identify the optimal energy production system and its optimal operation strategy required to satisfy the energy demand of a set of users in an industrial area. A distributed energy supply system is made up of a district heating network, a solar thermal plant with long...

This paper goes further with the aim at demonstrating the capabilities of the thermoeconomic approach to the diagnosis of energy utility systems. This paper deals with a common vocabulary, definitions of concepts and mathematical principles, and above all, focuses on the concept of malfunction,...

This work is the first part of a wider project aiming at demonstrating the capabilities offered by the thermoeconomic approach to the diagnosis of malfunctions in energy utility systems (TADEUS problem). The final goal is to create a common basis of work for people interested in applying...

The work deals with the realization, the experimental testing and the modelization of a small-size ORC (Organic Rankine Cycle) prototype. The main components of the circuit, filled with the refrigerant R245fa, are a plate condenser, an inverter-driven diaphragm pump, an electric boiler and a...

Small scale Organic Rankine Cycle (ORC) systems has been the object of a large number of studies in the last decade, because of their suitability for energy recovery and cogenerative applications.

Recently, several efforts have been devoted to the improvement of the thermal efficiency of small gas turbines, in order to approach the typical values of the internal combustion engines in the same range of power. One possibility is represented by a combined cycle, obtained coupling the gas...
