3E Analysis of the Effect of Different Type of Fans on Cooling Performance Applied to an Industrial Deep Freezer

In this study, two different industrial refrigerators were designed, manufactured and tested to analyze the impact of types fans (Type 1 Type 2) used in cooling systems on performance system. order test fan airflow effects, axial configurations with structures motor technology (EC shaded-pole induction) separate refrigerator rooms accordance TS EN ISO 23953-2 standards. R290 (Propane) was as a refrigerant systems. The average temperature relative humidity values environment where experiment conducted measured 25 °C 60 % (Class 3), respectively. During experiments, total 51.71 kWh energy consumed system 1, while 54.22 2 difference between consumption calculated 4.85%. temperatures inlet outlet evaporator -21.57 °C, -18.97 -23.43 -20.94 for -24.65 -26.44 While coefficient value type 1.74, it 1.54 second-law efficiencies 30.85 29.81 %, addition, environmental economy analysis carried out using amount CO2 that prevented from emitting emission price accordingly.
