Abstract
This study conducted a thermodynamic analysis of an air-source heat pump using R32 refrigerant to assess its effectiveness in meeting the heating needs of a residence in Kırıkkale province during winter. The air temperature in Kırıkkale was obtained from the Turkish State Meteorological Service according to the average of last ten years. Calculations were based on the heating season between October and April for the years 2022-2023. In the study, parameters such as heat gained from the environment, compressor energy consumption, the system's performance coefficient, and second-law efficiency have been examined. As the external air temperature decreases, the amount of gained heat decreases by approximately 9%. In this regard, the energy consumption of the compressor to meet heating demand has increased by approximately 40%. The results showed that the system performance was calculated as 5.545 and 3.957 for October and January, respectively. However, the second-law efficiency was observed to be 0.3266 for January and 0.2103 for October. The findings emphasize the varying performance of air-source heat pumps depending on climatic conditions.
