Ventilation & Comfort Modeling

Developing heating, ventilation and air conditioning (HVAC) systems takes into account factors such as room temperature, humidity and expected occupancy as well as heat loss through doors, windows and walls. Understanding air flow in a building, vehicle or any other environment is key to creating the best design of an HVAC system.

Cost containment and eco-friendliness are important considerations as well. Virtual modeling gives engineers the opportunity to test a large number of options in a short period of time. In this way, designers can come up with the most cost-effective, energy-efficient, and comfortable and appropriate system possible.

Software from ANSYS helps engineers model and analyze the complex geometries of a room or structure; at the same time, it offers powerful meshing utilities and CAD integration. 

Whether the project requires a simple analysis of room dynamics or more complex situations in which temperature, moisture, acoustics or sustainability must be considered, ANSYS software offers:

  • A wide range of turbulence models including RANS and LES
  • State-of-the-art grey and spectral radiation solvers that consider short-wave and long-wave radiation, window performance, shading, and solar gain
  • Conjugate heat transfer capabilities
  • Full one-way and two-way thermal and mechanical coupling of fluid and structural models for assessment of wind-induced distortion and vibration.
