Rezumat
In lucrare este prezentat un model matematic de optimizare a unui sistem PVT integrat intr-o unitate
industriala, in care este folosita continuu caldura obtinuta din sistem. Functia obiectiv a modelului este eficienta
energetica globala si eficienta exergetica globala a sistemului. Tinand seama de posibilitatea de variatie, s-au ales 3
parametri independenti: inclinarea panourilor, debitul de apa in PVT si configuratia serie-paralel a modulelor. Sunt prezentate cateva din restrictiile de tip egalitate care sunt relatii de definitie a diferitilor parametri dependenti.
Restrictiile de tip inegalitate sunt date de domeniul de variatie al parametrilor independenti. Este prezentata o simulare numerica care sta la baza concluziilor obtinute in lucrare.
