Thermodynamic and Exergetic Analyses of Power and Cooling Systems

This work is focused on setting up a methodology aimed to find the optimal CHP plant designs for users with thermal needs of various temperature level. A fundamental condition to ensure the Combined Heat and Power efficiency is that the thermal and the electrical power follow the user needs, in order to match with them. The thermal characterization is a necessary step to reach the goal: in fact, a qualitative temperature analysis must be done in addition to a quantitative thermal power one. In order to analyze the interaction between CHP unit and user needs, is essential to characterize the user thermal power and thermal efficiency: this analysis represents the central point of this work. The methodology is based on a multi-variable multi-objective procedure and it's adopted to examine which solutions would be able to achieve the best results in term of the Total primary Energy Saving (TPES) and the Simple pay Back (SPB) at the same time. The results of this methodology are shown with reference to three users, two hospitals and a pasta manufacturing plant.
