Our recently released product Autonomous HVAC CFD aka AHC is a CFD software for indoor room thermal comfort modeling. For a long time, it was necessary to know about CFD modeling, fluid properties, and mesh expertise for CFD analysis. The struggle was real and the time required from conceptual design, heat load analysis to CFD simulation was significant. AHC is such an autonomous software that only requires HVAC inputs such as diffuser size and type, heat load/loss report, and terminal unit details. All these parameters and you are set for performing CFD analysis. Our team consisting of technical CFD, software, and mechanical engineers have worked in coordination to deliver a full package product that can deliver richer and more visually appealing CFD results. From 2D reference to building a 3D model automatically using design automation feature without worrying about high-performance computing ability, our product has proven results to empower AEC industry to new levels.

AHC is a combination of multiple sets of solvers and a code designed in such a way that in fewer user inputs you can receive insights such as thermal comfort scale, temperature and velocity contour plots at every point, predictive mean vote, draft rating, mean age of air and so on the list goes on. AHC is regressively tested on its design results and the actual received results values. From variable air volume to constant air volume, the application can showcase your design conditions and simulated instance conditions with the space temperature achieved based on your thermostat location. Users can view the air stream in the form of a flow line coming from supply terminals up to the return terminals. A visual presentation of air movement behaviour that can affect room conditions can be easily achieved. A user can also simulate a condition in which the effect of high occupant density on HVAC apparatus can be viewed.

A contour plot is a two-dimensional representation in which all points with the same response are joined to form contour lines with constant responses. These are useful in order to indicate velocity and temperature distribution. It is a powerful tool for conveying information as well as for on-screen and presentational data analysis. Contour plots can be used to evaluate desired response values and operating scenarios. These are one of the major aspects of post-processing which displays a band of colors that can be classified according to Velocity, Temperature, Predicted Mean Vote (PMV), Effective Draft Temperature (EDT), % people dissatisfied, Draft Rating % (RH), Relative Humidity % and Mean Age of Air. AHC provides a feature of a cut plane which makes understanding contour plots easier as the user gets an option of viewing contour plots at various locations in space.

AHC is an interesting application that can open the gate for your technical and visual experience to deal with air conditioning problems. No more spending on issues faced post-installation. Get our early release application with free credits and give it a try!
