Abstract
In recent years, energy-efficient technologies, particularly Heat Pump Systems (HPS), have experienced rapid development in autonomous heating and cooling applications. This study evaluates the energy and exergy performance of a geothermal heat pump-based heating and cooling system designed for rural residential buildings.
Materials and MethodsThe study investigates the application of heat pump systems in heating and cooling installations using thermal engineering calculation methods. Energy and exergy analyses were performed, and the thermodynamic performance of a geothermal heat pump system was evaluated through analytical calculations.
ResultsA geothermal heat pump-based heating and cooling system for rural houses was developed. The results showed that with a compressor power of 2 kW, the evaporator extracts 7.5 kW of heat, while the condenser supplies 9.5 kW of heating power to the consumer. The ideal coefficient of performance (COP) was 4.75, whereas the actual COP, considering additional electrical energy consumption, was 3.8.
ConclusionThe obtained results demonstrate that the proposed geothermal heat pump system provides an energy-efficient solution for heating and cooling rural residential buildings. The system contributes to reduced energy consumption and promotes the effective utilization of renewable geothermal energy resources.
