A CFD Classroom Case Study
Obtaining efficient ventilation with overhead mixing systems for applications in heating climates can be a challenge. Not only does the positive buoyancy of the supply air work against the air distribution system, but most overhead mixing systems are designed with low supply air volumes (relative to cooling) and high supply air temperatures (more than 15°F above room temperature).

Defining Sensible and Latent Heating and Their Importance in HVAC Applications
In the HVAC industry, it is common to hear about having to handle sensible and latent loads to condition a space. Since we tend to associate heating or cooling with a change in temperature, confusion can arise when multiple forms of heating are mentioned. In this post, we’re going to clarify the difference between sensible and latent heating and why the distinction is important in HVAC systems.

Measures to Mitigate Condensation Concerns
More than ever before, engineers, contractors and building owners are choosing chilled beams for their projects. This energy-efficient technology uses the heat transfer capabilities of air and water to provide heating and cooling in a space. But the concept of installing a water coil within the housing of the chilled beam raises some very important questions: will there be condensation, and are drain pans required?
