Daikin Applied achieves performance improvement using TURBOdesign Suite

Daikin Applied of Minneapolis, Minn, a fortune 1000 company and the largest heating, ventilation, air conditioning (HVAC), and refrigeration company in the world developed a new, ultra-efficient compressor design potentially capable of achieving multimillion dollar performance gains by using TURBOdesign Suite. Turbomachinery design engineers and original equipment manufacturers (OEMs) worked to achieve higher performance levels to meet U.S. and international efficiency standards can take advantage of the 3D inverse design software system, TURBOdesign Suite.

"Daikin Applied’s target performance gain for this project using the TURBOdesign Suite software is 2.5 points of efficiency gain. We already have achieved more than a two-point compressor efficiency improvement."

The HVAC system represents a large percentage of a building’s energy use. Since the 1980s, manufacturers of HVAC equipment like Daikin Applied have worked to make their systems more efficient. This was originally driven by rising energy costs and therefore customer demand. It was mandated by governmental standards like those set by the U.S. Environmental Protection Agency Engine Testing Regulations and Europe’s Ecodesign Directive. There are several methods for making HVAC systems that meet or exceed new standards, including making individual components such as air conditioning system compressors more efficient.

"Our 3D inverse design optimization technology provides innovative solutions while reducing development time and costs," said Professor Mehrdad Zangeneh, founder and managing director of ADT. "By using the TURBOdesign Suite, Daikin Applied engineers were able to apply the 3D inverse design approach to directly use knowledge of detailed fluid dynamics, as provided by computational fluid dynamics (CFD) and detailed measurements, to arrive at a breakthrough solution that met efficiency goals."

In the 3D inverse design approach enabled by the TURBOdesign Suite, the blade geometry is computed for a given pressure or loading distribution. Since 3D pressure distribution controls the viscous behaviour of the flow, by controlling the 3D pressure field, it is possible to directly use the detailed information provided by CFD solutions to arrive at a choice of optimum loading and control particular sources of performance loss in turbomachines.

Register for our webinar

On Wednesday 1st February, we are running a free 1 hour webinar that will show how using the different modules in TURBOdesign Suite you can design high efficiency compressors rapidly from scratch. We will use an example of a small heat pump and show the following design process:

- Creation of real gas property tables (RGP) from REFPRO for the new refrigerant. - Meanline design of the compressor by using TURBOdesign Pre and the RGP files. - 3D design of the impeller by TURBOdesign1. - Optimization of the impeller geometry for multiple operating points by TURBOdesign Optima. - This webinar is offered several times. Select (click) the time that works best for you.
