The New Facility is Operational!

After several months of construction, and much longer planning, the new Krueger Lab, Training, and Demonstration Center is operational. We held an Open House a couple weeks ago and the first of our revamped Krueger Institute of Technology training sessions last week. During training, we demonstrated diffuser performance with smoke at several different discharge temperatures, including tests against our unique double sided Cold Wall.

The Reverb Room is operational, nearly twice the size of the one in Tucson AZ, and with far greater airflow and sound isolation capabilities than ever before. The Throw Bay is twice as long as our previous one. In Tucson, with the highly accurate omni-directional anemometers and computer acquisition system, we discovered that one could see the effect of an opposite wall when within 20 feet of it, severely limiting the ability to get accurate throw data at high airflow rates. The ceiling is up to 12 feet high against the Cold Wall on one side, against a raised floor on the other.

We have a full scale Hospital Operating Room set up with our Sterilflo particulate control system (air curtain and downblow panel). We give thanks to Steris for their lighting and operating table donations, which help demonstrate real world velocities at the patient location to assure compliance to ASHRAE 170.

We have a “standard” 2400 cu.ft. Acoustical Demonstration Room (‘In-Situ”) for demonstrating the radiated sound transfer from ceiling plenum located sound sources, such as fan terminals and fan coils. This space has a 3ft deep plenum with open sides, as required by many acoustical demonstration specifications; in addition, we have installed rails and a winch so we can rapidly change out units as requested.

We have an operational Fume Hood Laboratory with several operational variable volume vertical sash fume hoods and Krueger ceiling displacement TAD and RadiaFlo diffusers to demonstrate face velocities at the hoods with full airflow.

We have installed a raised floor against one wall of the double-sided Cold Wall. This raised floor has several different perimeter systems as well as an array of passive interior floor high induction swirl air outlets. The air system is configured to demonstrate displacement ventilation air outlets as well. This room also has several operational chilled beam units in the ceiling and includes a humidifier to show the response of the sensible cooling coils to room humidity levels.

Finally, we have a theater type training room with seating for 40 and power and internet connections for all. This space is conditioned using displacement ventilation.

The entire space surrounding these individual areas, including the workshop, has exposed duct work, which showcase the complex system of space conditioning and laboratory air delivery. All systems are controlled through an internally programmed LabView system with over 50 pressure transducers, several theatrical smoke generators, and connected flat panel monitors with iPad accessible on-screen displays.

We look forward to having many visitors come through to see this new series of spaces for both training and product evaluation, development, and demonstration.
