Gelžinis M. Analysis of efficiency for renewable energy sources/ supervisor dr. assoc. prof E. V. Nevardauskas; Šiauliai university, Technological faculty, Electric department. Šiauliai, 2010. 49p. Issue of this paper is the efficiency of the heating system with heat pump . Aim of this paper is evaluate the heating system with heat pum efficiency. The main tasks is to calculate building heat demand , to examine the potential of energy saving measures and their cost, explore operating principle of heat pump, suggest possible directions in development of heat pumps, compare theoretical calculations with measured data .The paper olso provides evalution of alternative heating systems, comparation of energy costs for different heating systems, calculation of pay back period for heat pump. The conclusions and recomendations are given. This thesis cam be useful in selection of heating system for building , and selection of heat pump type. |
