DuctSox says its new C-Series Fabric Diffuser offers a 360-degree air distribution solution for HVAC systems. Ideal for a variety of spaces, including warehouses, manufacturing plants, retail, fitness, and convention centers, the C-Series drop-down plenum diffuser provides facilities with directional control of their indoor airflow system in spaces where traditional ductwork is not an option.

Education will always be an important aspect of the HVAC and engineering industry.

Greenheck has added Model RBD-15 to its line of remote balancing dampers. Constructed of heavy gauge galvanized steel, Model RBD-15 is a multi-blade balancing damper rated for pressure differential up to 4 inch wg. and velocities up to 2,000 fpm.

Commercial kitchen ventilation (CKV) has been a challenge to mechanical engineers for years. Part of the challenge comes from the fact that the mechanical engineer is normally not the “kitchen consultant.

This article describes the remodeling of a hospital kitchen in which workers experienced high temperature and humidity levels, as well as turbulent airflows most of the year.

Titus has released the TJD, a standard OMNI diffuser designed specifically to address low air volume codes. According to the company, while most air outlets typically work at 100 cfms, the patent pending TJD performs at 20 to 50 cfms and throws air at 50 ft per minute up to 9 ft from the diffuser. The high mixing increases the discharge isovel and its throw, providing uniform temperatures and equally distributed outside air throughout the space.

Air distribution in a space and diffuser selection is simple, right?

Spot exhaust is a unique design engineering challenge. The 2015 ASHRAE Handbook – HVAC Applicationscovers a broad spectrum of applications in just about all the comfort applications (chapters 1 through 13) and industrial applications (chapters 14 through 33) with personal safety an integral part of chapter 32. But spot return air doesn’t get much press in ASHRAE.

In last November’s Back2Basics, I created a test for the readers based on the idea that the patient room design was similar to a pharmaceutical cleanroom, with an air lock for people to enter and leave the room.
