The purpose of this study is to explore the impact of installing an axial fan in the evaporator of a domestic refrigerator. A test rig was designed and fabricated, and experiments were conducted using R134a refrigerant to evaluate the refrigerator’s performance with and without an axial fan.
To further understand system behavior and performance, a refrigeration unit analysis was performed using CoolPack simulation tools version 1.50 to model the system’s behavior. The results demonstrated a significant improvement in the coefficient of performance (COP) and refrigeration effect, with the system achieving an 11.2% performance increase when the axial fan was installed. Moreover, compressor work was reduced by 6.8%, indicating a decrease in energy consumption.
Beyond performance gains, this study demonstrated that equipping the evaporator with an axial fan can significantly enhance the performance of domestic refrigerators. This reduction directly correlates to improve energy efficiency, indicating that the integration of an axial fan not only boosts cooling effectiveness but also lowers energy consumption—an essential factor in residential energy use.
