Achieving net-zero carbon emissions by 2050 is a global priority, making energy-saving essential for enhancing competitiveness. However, to many companies' dismay, factories struggle to go green due to the overwhelming complexity of their electrical equipment.

In buildings, the biggest energy-saving opportunities lie in the HVAC systems and fluid equipment, especially in motors. A study in 2017 by Taiwan’s Industrial Technology Research Institute found that motors consume nearly 70% of industrial electricity in Taiwan. Globally, motors in refrigeration, air compressors, fans, and pumps consume about 45% of all electricity. By making motors more efficient, energy consumption can be greatly reduced.

Three major trends in HVAC and fluid equipment include improving energy efficiency, reducing harmonics, and creating user-friendly interfaces. As carbon reduction regulations come into effect globally, making motors more efficient is critical. Harmonics can damage power quality and cause equipment failures, which is why the IEC 61000-3-12 standard requires that commercial HVAC systems keep total harmonic distortion below 48%. Additionally, with the growth of the Industrial Internet of Things (IIoT), equipment such as pumps, chillers, and compressors can now be monitored remotely. This enables predictive maintenance to prevent unexpected downtime and increase equipment reliability.

Delta offers comprehensive green solutions for the HVAC and fluid equipment sectors, including the High-Speed Fluid Solution, PMa Synchronous Reluctance Motor MSI Series, and Direct-Drive Variable Frequency Cooling Tower Solution:

● High-Speed Fluid Solution:
The secret behind enhanced space and cost efficiency is maglev technology. Moreover, this solution integrates motor drives, high-speed motors, magnetic bearings, and power management systems. The oil-free magnetic bearings remove the need for traditional gearboxes and oil cooling, simplifying installation and maintenance, and cutting space and costs. Delta's HMI one-touch setup with built-in programs also speeds up implementation.

● PMa Synchronous Reluctance Motor MSI Series:
Designed for the fluid industry, the MSI Series meets high-efficiency IEC standards. It’s ideal for long-duration, low-load operations. Compared to induction motors of the same power, the MSI Series is more compact, offering higher installation flexibility and enhanced efficiency. For example, a Delta factory installed the MSI Series motors in its refrigeration pumps and reduced energy consumption by 9.6%.

● Direct-Drive Variable Frequency Cooling Tower Solution:
Combining Delta's High Performance Compact Drive MH300 Series and permanent magnet motors, this solution follows a direct-drive design that cuts maintenance costs. Tests show a 19.7% increase in energy efficiency compared to traditional equipment. The system meets Taiwan's IE3 standards and can achieve the stricter IE4 or IE5 standards required in Europe and the US.

Delta helps clients in various industries adopt HVAC and fluid equipment solutions, starting with energy consulting to site condition assessment and identifying key issues. By combining high-efficiency products with comprehensive solutions, Delta maximizes energy savings, speeds up green transformations, and balances economic and environmental benefits for a win-win outcome.
