Optimize HVAC Designs

CAE for Heating, Air Conditioning and Ventilation Applications

SimScale is a 100% cloud-based CAE software for HVAC simulation that lets you test, validate, and optimize your designs through CFD, heat transfer and thermal analysis.

Staying competitive requires engineers to constantly innovate and find new ways to improve their designs while reducing the development costs and time to market. Computer-aided engineering (CAE), also called engineering simulation, is becoming the industry standard for developing HVAC products better, faster and cheaper. Using cloud-based CAE with SimScale, HVAC engineers worldwide are performing computational fluid dynamics, conjugate heat transfer and thermal analyses for testing and optimization of heating and cooling equipment, air conditioning, ventilation systems and more. The SimScale platform enables you to test several design versions early in the design process and make fast product improvements within minutes, based on the results. Simulate the cooling and heating performance, energy efficiency, thermal comfort, air quality and structural integrity of your design with SimScale! All 100% in your web browser.

HVAC Equipment Optimization

 With CAE, you can predict the performance of rotating machinery like industrial fans, vents, compressors, pumps or blowers. In addition, CAE helps to minimize pressure drops across ducts and other components. SimScale can also be used to optimize heating equipment. Everything with one simulation tool, 100% in the web browser.

Energy efficiency

Reduce energy consumption for HVAC systems via better heat exchanger designs, ducting, fan or cooling unit placement and get energy efficiency certification for buildings, data centers and equipment. SimScale helps engineers develop products that comply with and exceed current quality standards and regulatory provisions.

Cooling and heating

Improve thermal management of machinery, heat sinks or engines. Optimize electronics cooling on all levels (from chip to room), predict resulting temperatures in product’s case, reduce failure risk and decide on fan placement, sizing and speed for cost-efficient cooling.

Thermal comfort

In HVAC system design, it is crucial to ensure optimal thermal comfort for people, whether it’s at home, in the office, a plane or a car. SimScale can help predict thermal comfort by testing different air supply outlets, their placement or number, and evaluating the temperature gradients, air distribution or velocity plots.

Contamination Control

Air quality is essential in interior spaces. Use SimScale to ensure a fast and efficient removal of high contaminant concentrations in parking garages, predict smoke propagation for safety control in tunnels or subway stations, develop an intelligent ventilation strategy and optimize cleanroom designs.

Wind Engineering

SimScale is used in wind engineering, to predict wind loads on structures or visualize the effects of new buildings on urban airflow fields. Civil engineers can now use cloud CFD to test architectural designs or reduce contaminant dispersal from industrial facilities, by analyzing environmental flows.

I am really satisfied with the results that I’ve gotten for my heat exchanger simulation. And in this regard, I should mention that SimScale has a nice built-in option to control results by tracking values of different fields while a computation is running. It’s a bit tricky to implement such a thing on your local PC.
