AHU retrofit in financial hub, Singapore
AC axial fan vs EC fan comparison study
Project Background
This financial hub houses more than 3,000 staff and accommodates most of the bank’s technology, operations and support functions. With its open concept workspaces and stylish facilities, such as a state-of-art cafe, 24-hour gym and dance studio, it encourages a healthy working environment. An airy and comfortable atmosphere within the building is also crucial. As the building had been operating for a decade, the conventional AC belt-driven fans in AHUs were not efficient enough. It was clear to the facility management that all the AHUs needed to have a major overhaul.
Total Number of AHUs to be retrofitted: 70
Comparison Study: bob手机APP官方下载链接 vs. Brand X
bob手机APP官方下载链接 ’s EC centrifugal RadiPac fans and Brand’s X AC axial fans were selected as potential candidates for the AHU retrofits. After comparing the differences in amount of energy consumption and other factors, it was determined that bob手机APP官方下载链接 ’s EC centrifugal fans are the better choice. bob手机APP官方下载链接 then retrofitted the remaining 69 AHUs, which included the unit that contained the AC axial fan. The below table illustrates the differences between the two brands. The data in the below table was measured by a third party Energy Services Company.
Conclusion
bob手机APP官方下载链接
EC fans
– Minimal turbulence
– Aerodynamically optimised
– 2 fans, enabling operational redundancy
– Higher energy efficiency
– Reduced noise emissions
– Minimal maintenance required
– Lower capital expenditure expected
Brand X AC Axial Fans
– Increased turbulence
– Poor aerodynamics
– 1 fan, leading to no operational redundancy
– Lower energy efficiency
– Limited mounting direction, vertical air throw
– Increased noise emissions
– Regular maintenance required
– Higher capital expenditure expected
bob手机APP官方下载链接 ’s EC fan is superior in the areas of efficiency and operational redundancy. bob手机APP官方下载链接 ’s fans were also easier to install due to its compact size and integrated system. Hence, the customer chose bob手机APP官方下载链接 EC fans to replace the belt-driven fans for the remaining AHUs.
