Rezumat
Recuperarea caldurii uleiului de racire a transformatoarelor de putere este in atentia specialistilor atat din
domeniul electric cat si termic. O solutie de recuperare a acestei calduri pentru obtinerea unui agent termic cu
temperatura ridicata ce poate fi utilizat atat pentru incalzire, racire, cat si pentru apa calda menajera, este propusa in aceasta lucrare. Sunt prezentate modelul termic al transformatorului si modelul analitic al pompelor de caldura cu
compresie si cu absorbtie. In final, este aratat un exemplu numeric

Abstract
Heat recovery from cooling oil of power transformers is in the attention of specialists from both electrical and
thermal field. A solution of this heat recovery to getting a high temperature of thermal agent which can be used both for
heating, cooling and domestic hot water is proposed in this paper. The thermal model of transformer and analytical model
of compression heat pumps and absorption heat pumps are presented. Finally, a numerical example is shown
