The chemical-free air curtains
from Berner International, based in New Castle, Pa.
For designs that include air curtains
, they are generally created using a couple of linear slot diffusers with supply plenums, which, similarly, are designed to deliver air evenly over the length of the air slot.
The corresponding air curtain
velocities are measured by a Sierra-600 hot wire anemometer having an accuracy of 1% of the measured value in the range of 0-2 m/s (0-6.
The airflow from the vertical air curtains
was directed at a 45-degree angle across the doorway.
However, flow field visualization tests showed that when more than one air curtain
was operating, the curtain closest to the dissemination room showed some instability.
The air curtain
, an invisible wall made up of jets of air, has been used as a baffle to direct flow to a more desired path.
Based on similar experiences following Hurricane Andrew, the engineering consultant supplied technical specifications on the operation of refractory type air curtain
burners and air quality test results.
The Walk-In cooler Efficiency Kit includes a pre-wired control/load center with enclosure, magnetic reed on/off door switch and a K-Zone air curtain
that's engineered specifically for walk-in coolers/freezers, according to company officials.
Having identified the need for the tools which enable identification of the performance of a tilted air jet, the objective of this present work is to develop a model-based design methodology for the establishment of tilted air jet plane, that will facilitate the design and or evaluate existing designs and in particular the effects of the inclination angle of the jet on the performance of the air curtain
Visualizing the OR as being negatively pressurized by means of exhausts covering all four walls would make it easier to picture just how an air curtain
Biddle--the company whose research led to a breakthrough in air curtain
technology--has launched a short film to highlight the problems associated with inefficient barriers between internal and external environments in coldstores.
After a number of years of painstaking research, trials and in-situ improvements, the end product--an 'airwall'--has resolved the snags of conventional air curtain
technology in this type of application.
