Cloud-based simulation allows for more accurate HVAC designs

MUNICH—Radiation heat transfer analyses using computational fluid dynamics (CFD) are now available within the SimScale platform, SimScale said in a press release. SimScale is the provider of what is reported to be the  first production-ready software-as-a-service (SaaS) application for engineering simulation.

Heating, ventilation, and air conditioning (HVAC)  engineers continually seek optimal temperature and airflow levels for the comfort of building occupants, and to meet or exceed industry standards. In the initial design phase of an HVAC project, engineers can now simulate radiation as part of thermal comfort analyses within the cloud-based SimScale platform. As a result, they can more accurately and efficiently iterate their HVAC designs, the company said.

“The inclusion of radiation, along with standard conduction and convection analyses, is a key ingredient to accurately predicting how placement of HVAC components, such as outlets, air conditioning units, or heaters, will affect the temperatures and airflow felt by occupants,” said Jon Wilde, vice president of customer success at SimScale, in the release. “Accurate thermal comfort analysis means better wellness and productivity for occupants and the avoidance of expensive HVAC configuration changes later.”

SimScale users can simulate the effects of radiation to optimize a comfortable environment within a room or an entire building, including office spaces, residential dwellings, or theaters.

According to a University of Chicago study, hot weather can cause people’s regular productivity rate to drop by 4 percent per degree. Conversely, if employees are too cold, they may become distracted from work or even type more slowly. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) developed the standard ASHRAE 55, which is used for specifying the combinations of factors that produce thermally comfortable environmental conditions that will be acceptable to a majority of the occupants.
