This paper focuses on the development of a dynamic multi-level model for simulating of a solar cooling system adopting an adsorption chiller. The model integrates detailed simulation of the adsorption cycle (component level) into the transient simulation of the solar cooling system (system...

The manufacture of low-cost parabolic trough collectors (PTCs) for industrial process heat applications ranging from 70 to 250 °C is crucial for the widespread availability of this solar technology. Thus, we present a prototype of a PTC with a 90° rim angle and a small concentration ratio of...

The site-specific nature of renewable sources, the need to involve citizens in the energy-planning process and the perspective of local governments, who are the first governmental stakeholders involved in the implementation of energy-saving initiatives, has recently emphasised the strategic role...

This paper deals with the efficiency of electrical energy generation in the thermopower plants in Italy. A method based on the principles of Data Envelopment Analysis (DEA) was used to assess the conversion efficiency of each power plant based on a set of input data. The analysis was conducted...
