Heating, ventilation and air conditioning (HVAC) equipment manufacturers face challenges in achieving and maintaining technology leadership. There is fierce global competition and continuous customer demands to consistently develop and deliver new, higher-performing products in terms of noise reduction, energy efficiency and reliability. Moreover, there is a growing pressure to design HVAC components faster so that they can be delivered to the market more quickly. Simulation Driven Product Development is the solution from ANSYS to these challenges. Through virtual prototyping, a designer analyzes the performance of various equipment designs during the early stages of product development. Because solutions from ANSYS have unparalleled breadth across multiple disciplines, engineers can apply mechanical, fluids, and multiphysics software to a wide range of HVAC equipment design including:
For example, computer simulation is being applied to fan design. Modeling techniques using ANSYS tools provide engineers with the ability to accurately model the performance of design concepts; consequently, this reduces the number of physical prototypes that are tested. This makes it possible to evaluate many more designs, usually resulting in a substantial improvement in performance. At the same time, the lower cost and shorter design cycles that accompany simulation (compared to using physical testing only) provide faster time to market and reduced development costs. Design analysis of parts and assemblies in the HVAC industry may involve complex computer-aided design (CAD) assemblies. To accurately handle these geometries in the design process, ANSYS offers close connection with CAD to access geometry and material parameters; it also allows quick turnaround while preparing geometry for analysis. Geometry creation and editing tools allow geometry manipulation for physics-based meshing and analysis. Engineers use software from ANSYS to design rotating equipment in industrial chillers and air conditioning equipment using rotordynamics simulation capability. The ability to import full 3-D CAD models into the ANSYS Workbench environment allows engineers to analyze accurate 3-D models instead of creating simplified 1-D representations of the geometry. Productivity tools, such as automatic contact detection, allow for easy problem setup and more time spent on engineering design decisions. To survive in today’s global economy, manufacturers need to be inventive in terms of factory equipment and raw materials as well as with the processes they develop. Using simulation-driven design efforts can bring value and innovation to a wide range of product development applications. HVAC manufacturing companies have reported that the software tools and services from ANSYS related to design and analysis help them trim several weeks off time to market. |
