What is BACnet?

Price has chosen BACnet, the ASHRAE building automation and control networking protocol, for its products since it has many benefi ts. Some of the benefi ts of BACnet include: Low cost hardware allows networking almost any device Supports multiple LAN technologies (Ethernet/MSTP) BACnet is an ANSI/ASHRAE standard All networked Price products use the BACnet standard for communication, meaning all products will work together as a system without any special programming or protocol converters (gateways). This ensures reliable operation in the fi eld and allows the building owner to expand their system around a standard communication protocol.

The Price Radiant Test Chamber is essentially a room within a room. The lab started with the shell of a walk-in freezer, into which was built a fl oor, four walls and a ceiling of Radiant Panel allowing the control of each surface temperature in the room. Below the active ceiling is a Price HDCR test ceiling that retains the panels or beams under test and allows for quick reconfi guration and adjustment. The tests are controlled by four water loops: a chilled water loop, a hot water loop, room surface loop and a test product loop. A computer measures and controls the temperature and water fl ow in each of these loops, along with the power of the EN standard load simulators in the room. The supply air volume and temperature required for the testing of active chilled beams on the system can also control hybrid systems.

Product Testing

The vast majority of the data available on the market today is highly dependent on interpretation by the engineer. The lack of industry wide testing procedures for radiant products and chilled beams has led to confusion in performance as well as diffi culty in comparing between manufacturers. Recently, benchmark testing for Radiant Panels and Chilled Beams has become available, in the form of European Norm (EN) standards. The Price Radiant Test Chamber has the capability of testing to EN standards 14037, 14240, 14518 and 15116 relating to the heating and cooling with Radiant Panels as well as the performance of Passive and Active Chilled Beams, respectively. This Chamber will be used to generate the fi rst comprehensive set of standardized and accurate performance data in the industry.

Completed in 2007, the Price Noise Control Sound Lab is a second generation state of the art acoustical testing facility. From ground breaking through commissioning, great care has been taken to ensure that the sound data being produced by the lab is accurate, repeatable and the most reliable in the industry.

Control Center

Reverberant Sound Chamber

The solid concrete Sound Source Chambers generate up to 120 decibels of overall sound pressure level using 4,000 watts of power. These high sound levels allow us to attain accurate insertion loss measurements for long silencers, and give us the fl exibility to test a very wide range of products. All components of the lab have been designed to meet or exceed Test Duct Work the current ASTM E-477 standard for testing acoustical duct silencers. As you enter the Price Noise Control Sound Lab, you immediately see an acoustical plenum and two branch ducts that extend above to the full height of the 17 foot ceiling. One 36 inch duct loops down to the Straight Duct Testing Source Chamber and the other 28 inch duct hugs the ceiling and travels 60 feet to the second Source Chamber that is used for testing elbow silencers. The Control Center houses the heart of the operation; a data acquisition system, frequency analyzer and sound generator leaves nothing to chance.

The Test Duct Work employed in the system had to be designed ROOM 2 MOCK-UP to minimize sound break-out and break-in of the high test signals produced by the Source Chambers. Multiple layers of sheet metal, drywall mass, and insulation were employed to keep the sound power levels in the general lab area below 70dB. SOUND ROOM The Noise Control Fan Room consists of a 30,000 CFM bi- REVERBERANT directional axial fan that can ramp up to 4 inches of static Branch Duct Work pressure. To ensure that quiet acoustically treated air is used for silencer testing, a range of different noise control solutions were employed including Axial Fan Silencers (AFS), Rectangular EQUIPMENT Silencers (RL), Acoustical Plenums (Price Quiet-Line), and MECHANICAL Custom Elbow Plenums. Two airfl ow measuring stations are used to attain accurate airfl ow and pressure drop data.

Adjacent to the large Reverberation Sound Chamber, we have CHAMBER made provision for a second Reverberation Sound Chamber that RADIANT TEST will allow us to perform transmission loss testing for products like Acoustical Panels, Louvers and Cross-Talk Silencers. SOUND LAB NOISE CONTROL www.price-hvac.com 27 NOISE CONTROL SOUND LAB

Reverberant Sound Chamber The key to any successfully constructed sound lab is the Reverberation Sound Chamber where the sound levels are measured. To achieve a high level of accuracy for measurements as high as 10,000 Hz and as low as 50 Hz, the Reverberation Sound Chamber was constructed with size, dimensions, mass and acoustic isolation in mind. The result is an amazing looking structure that weighs over 750,000 lbs, fl oats on spring isolators and is completely isolated from the rest of the building for both vibration and sound infi ltration. The room is designed with a Discharge Silencer that can handle up to 60,000 CFM of airfl ow for testing Axial Fan Silencing systems and can accommodate up to a 12 foot x 12 foot duct connection through the test wall.
