The Heat Pump Systems – an Option for Energy Efficiency and Innovation of Technologies


  • Stefan Ditchev University of Food Technologies – Plovdiv, Bulgaria



heat pump systems, energy efficiency, refrigeration processing


The report refers to the wider practical application of heat pumps in terms of rational use of energy resources; energy efficiency; environmental efficiency and technology innovation. Energy conservation, reduction of carbon footprint in energy production and consumption and technology innovation are global issues. The paper focuses on low potential energy sources needed to heat pumps, types of heat pumps, main guidelines and challenges when using heat pumps and the experience of experts from the Bulgarian school.
