Analysis of possibilities for heating and cooling of Faculty of Engineering University of Kragujevac with heat pump

Abstract

Humankind needs enormous amounts of energy, from which a large portion is consumed for heating and cooling homes and buildings. A huge amount of consumed energy causes high bills, especially when it comes to the old, big and energy-inefficient buildings. For that reason, in this paper is shown a study of replacement of existing heating methods in building B, Faculty of Engineering University of Kragujevac. A new method of heating involves the use of geothermal heat pump, which is reliable, comfortable and environmentally friendly way to use renewable energy sources. The calculation of heat losses is done, on the basis of which appropriate heat pump was chosen. Then, according to the investment costs and savings in consumed energy, payback period of the system is calculate in three different versions, depending on the number of operating hours of the heat pump and different electricity tariffs during the day.
