MONITORING OF SYSTEM PERFORMANCES OF A FULL THERMAL ENERGY PLANT-UNCERTAINTY EVALUATIONS

摘要

This work proposes the development and characterization of innovative domestic heating system driven by solar assisted heat pump in order to increase the system efficiency. A suitable on-line measurement system of overall observable quantities has been integrated in the plant, to give accurate and updated measurements of all the variables interesting the whole system. A more detailed analysis of quantities that main influence the system performances has been carried out, developing a suitable mathematic model able to describe and control the behaviour of interested phenomena. Finally some information about reliability degree of model has been provided. The use of advanced control and monitoring of several interested quantities has allowed optimising the global system efficiency.
