Application of Air to Water Heat Pump in Serbian Climate Conditions

Abstract

According to Article 20 of the Treaty establishing the Energy Community, the Republic of Serbia has accepted the obligation to implement European Directives in the field of energy efficiency and use of renewable energy sources (hereinafter RES). The introduction of the Directives into National legislation has resulted in numerous changes and amendments to the laws and bylaws, followed by national action plans and strategies. The paper gives an overview of National Action Plan for Renewable Energy Sources developed by Ministry of Energy, Development and Environmental Protection of the Republic of Serbia, analyzing available potential of RES use. The major goal is to decrease energy consumption in the field of heating and cooling by combining energy-efficient techiques and application of RES. In this paper, special emphasis is placed on the application of heat pumps using outdoor air as a heat source. Analyzed are operating conditions of the heat pump during heating seasone, using weather data for Belgrade. The estimated energy savings and reduced heating costs are presented in comparison with the measurement results. The results are discussed in terms of reduction of energy consumption and cost effectivness of heat pump application.
