CONSIDERATIONS ABOUT EFFICIENT USE OF GEOTHERMAL HEAT PUMPS

Autor/autori: Lecturer Eng. Roxana GRIGORE, PhD, Prof. Eng. Aneta HAZI, PhD

Rezumat: Pompele de caldura sunt vazute ca niste solutii rationale, durabile de valorificare a cantitatilor de caldura preluate din mediul ambiant, cu un consum redus de energie si in conditii de poluare minime. Lucrarea studiaza patru cazuri distincte, diferentiate de temperatura aerului exterior, caracteristica fiecareia dintre cele 4 zone climatice in care este impartita Romania. Se determina eficienta energetica si economica a utilizarii pompelor de caldura pentru incalzirea unei locuinte unifamiliale in fiecare dintre cele patru cazuri analizate.

Cuvinte cheie: pompe de caldura geotermale, coeficient de performanta la incalzire, valoarea investitiei.

Abstract: Heat pumps are seen as some sustainable and rational solutions to use the heat taken from the environment, with low electricity consumption and in minimal pollution conditions. This paper studies four different cases, differentiated by outdoor air temperature characteristic each of the four climate areas where is divided Romania. Thus are determined the energy efficiency and economic use of heat pumps for heating for a house in each of the four analyzed cases

Keywords: geothermal heat pumps, heating seasonal performance factor, investment value
