Renewable energy sources: analysis of two different alternatives of the heat pumps

摘要

As the energy prices are constantly rising, the energy management is currently a very important issue. One of the main reasons is that obtaining the primary energy sources like oil is much more difficult than in the past. This may lead to the exhaustion of worldwide resources. The use of different sources e.g. solar and geothermal energy etc. could be seen as a potential way of improving thermal energy management. The implementation of heat pumps as the primary source of heating and cooling in buildings, compared to installations using fossil fuels has become increasingly economical. This is due to increasing prices of fossil fuels, which is directly influenced by their accessibility and limited quantity. In addition, heat pumps contribute to the energy objectives of the European Union set for 2020. It specifically deals with achieving energy savings, reducing CO_2 emissions and increasing the share of renewable energy by 20%.
