BACKGROUND OF THE INVENTION
As the global concern for environmental issues, particularly Global Warming, continues to grow, there is an increasing need for sustainable and energy-efficient solutions. One significant area of focus is the design of systems that contribute to human comfort, especially in cooling applications where substantial energy is consumed.

Yet another objective of the present invention is to provide a system that minimizes energy consumption and contributes to environmental sustainability.
Yet another objective of the present invention is to focus on refining the Axial Fan's characteristics to enhance its overall performance, thereby positively impacting the efficiency and effectiveness of the entire cooling system.
Yet another objective of the present invention is to optimize the Axial Fan design to minimize noise generation during operation, promoting a quieter and more user-friendly cooling system.

The orifice is fitted in conjunction with the optimized axial fan, the optimized axial fan is placed between the condenser coil and the orifice. Herein, the condenser assembly acts as a resistance to the airflow causing a pressure drop and hence a high static pressure is required to complement this pressure drop. Herein, the optimized axial fan generates high static pressure that helps to suck more air from the ambient towards the condenser assembly thus causing fast cooling of the condenser assembly that reduces the power consumption for rotating the optimized axial fan. Herein, the blade angle is kept low on the leading edge and is kept high on the trailing edge, thus air enters the leading edge with low speed and high static pressure and exists the trailing edge with high speed and low static pressure that generates high static pressure that helps to suck the air from the ambient. Herein, the blade tip angle helps reduce vortex generation and increase the flow stability and velocity, that reduces the pressure loss and increases the overall static pressure generation. Herein, the groove reduces the noise and optimizes the power consumption. In an embodiment, the fan hub includes a bush and a motor. The motor is connected to the bush.
