Abstract. Introduction. In recent years, the application of energy-efficient technologies, particularly heat pump systems (HPS), has been rapidly developing in autonomous heating and cooling supply systems. Methods and materials. This article investigates the application methods of HPS in heating and cooling systems, as well as their energy and exergy analysis using thermal engineering calculation methods. Results. A thermal scheme of a geothermal heat pump-based heating and cooling system for rural houses was developed. It was determined that when the compressor power of the HPS is 2 kW, the heat obtained in the evaporator reaches 7.5 kW, while the heat power delivered to the consumer through the condenser equals 9.5 kW. The ideal coefficient of performance (COP) was 4.75, whereas the real COP, considering additional electricity consumption, was 3.8. Conclusion. The calculation results demonstrated that the geothermal heat pump-based heating and cooling system for rural houses is energetically efficient.
