Getting the right airflow from a fan is critical to the overall performance of any refrigeration equipment. Manufacturers run many exhaustive tests to ensure that the correct motor power, speed, fan blade diameter and pitch are selected to give the best overall performance for their piece of equipment. With the introduction of the energy saving EC (electronically commutated) fan motors, many companies are retro-fitting stores refrigeration equipment to achieve much improved energy consumption but are they fitting the correct fan/motor combinations in line with the original equipment design?
The fundamental of wind tunnel design concept is acquired from international standards set up by American National Standards Institute (ANSI) and the European ISO standards. Figure 4 illustrates the wind tunnel/test designed by Samuel and Jordan at the School of Engineering, University of Lincoln.
On completion of the wind tunnel/ test rig experimental measurements, Computational Fluid Dynamics (CFD) will be employed to quantify detailed flow structures for the wind tunnel system and performance assessment.
Conclusively, the new facility will give Pole Star Products the ability to thoroughly test new products (specifically EC fans) ensuring that they meet the specifications of the original cabinet manufacturers. Working with the University of Lincoln’s School of Engineering students enables them to put into practice some of the theories learned and helps them to “get a feel” for working in industry.
