The Science of ComfortTM
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.

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?

Integrated operating room ceiling systems consolidate multiple services in a single system to streamline supply, installation and on-site coordination. Price Industries’ Ultrasuite® system (pat. 10,401,049) combines hospital-grade LED lighting with precision-equalized laminar airflow diffusers to eliminate the traditional “light ring” and open valuable ceiling space for surgical equipment – all while mitigating contamination in the surgical zone.

The main goal of operating room air distribution design is to maintain a hygienic surgical zone around the patient and surgical team. Patient well-being is critical, and a well-designed air distribution system can help mitigate surgical site infections.

Laminar flow is a type of fluid motion characterized by smooth parallel layers, or laminae, that can slide relative to each other with little to no mixing. This is in contrast to turbulent flows, where chaotic changes in pressure and velocity can be observed as vortices, or eddies (reverse swirling currents), and where much more mixing occurs within the fluid.
