HVAC simulation technology provider SimScale is streaming a 30-minute webinar Dec. 19 (11:30 p.m. EST, 10:30 p.m. CST, 8:30 p.m. PST) that will teach engineers how to virtually test, compare and optimize ventilation systems from any computer at any time with cloud-based simulation. Company CEO David Heiny will evaluate the air-conditioning performance in a partitioned room using two different ventilation systems: mixing ventilation and displacement ventilation.
A displacement ventilation system is an air distribution strategy that introduces conditioned outdoor air at a low velocity from air supply diffusers usually located near floor level. With this system, the cool air accelerates because of the buoyancy force, pooling near the floor level, and is then carried up into the thermal plumes that are formed by heat sources. This type of air distribution strategy can effectively deliver fresh air to occupants and remove contaminants.
However, the right design strategy must consider a variety of factors. For example, supplying air from diffusers located near floor level has significant design implications. The air must be supplied at higher temperatures and lower velocity in order to avoid uncomfortable drafts. This implies that the air diffusers need to be much larger than those of other ventilation systems. At the same time, delivering air at a lower velocity allows fans to run more slowly, lowering the energy consumption.
Engineering simulation is one of the tools that play a fundamental role in those early product development stages, allowing engineers to make more informed design decisions earlier in the process. For the final product, this can mean lower production costs, more efficient energy consumption and lower failure risk.
During the “Displacement Ventilation Design with CFD” webinar, six scenarios will be discussed by Heiny and computational fluid dynamic simulations will be performed in the web browser with SimScale to examine temperature distribution and local thermal comfort.
Attending doesn’t require any simulation or engineering knowledge. As for the software needed, SimScale provides free access to its Community account. As it is a cloud-based tool, the only thing you need is a normal PC or laptop and an Internet connection.
If you are in a different time zone or cannot attend the live webinar, the organizers will be sending all the recordings by email. All you need to do is register.
