Daikin Applied remains the largest HVAC manufacturing company in the world by staying competitive. This is in part achieved via vigilant research and development, which means staying in touch with leading technology and keeping up with trends and best design practices and methods. For Guy Phuong, Development Engineer at Daikin Applied, 3D Inverse Design methodology seemed like a way to effectively and quickly develop viable designs. Based on his research and product demonstrations, Phuong found that turnaround times using 3D Inverse Design were faster than with traditional methods, especially when training a younger generation of designers. He decided it was the design practice to use.
In the past, Phuong’s team used traditional approaches, such as using blade and flow angles, which required in-depth familiarity with both impeller aerodynamics and with the design software programs just to be able to even come close to viable designs. It was a slow, cumbersome practice that needed to change.
“We are always constrained by development time,” said Phuong. “So, we were looking for ways to cut development time in addition to achieving the efficiency goals. TURBOdesign Suite was the only commercially avialable 3D inverse design software. We decided to use it.”
Implementing TURBOdesign Suite did not require very much in terms of time, training or hardware. Phuong had used the software at a previous employer. According to Phuong, becoming an advanced user was easy, taking only a few days working with ADT engineers. It took just three months for Phuong to feel completely comfortable and confident with it. For others at Daikin, training took about two days, and going from beginner to immediate took about three months.
TURBOdesign Suite software is not hardware intensive. It runs on Windows systems and operates on mid-range workstations with 2.4 Ghz or better processors, 2 GB RAM and 1Gb disk space, so it can be installed on most personal laptops. Therefore, no additional hardware was required to implement it at Daikin Applied.
The main TURBOdesign Suite feature used by Daikin Applied in developing their new HVAC compressor design was the blade loading window. Blade loading has the largest impact on the blade shape and thus blade performance, so this is what was changed the most to come up with the optimum blade design. Phuong found that it was easy to implement design changes without having to worry about blade and flow angles. TURBOdesign Suite enables quick geometry generation and thus quick optimization as well.
