Pressure Control Strategy Creates Silent Airflow for Hospital Patients

The Beckley ARH Hospital in Beckley, WV is the second largest provider in Raleigh County, WV with a 173-bed, acute care facility that includes 60 psychiatric beds and a level IV Trauma Center Emergency Room.  Quiet and consistent airflow was a priority during its construction in 2013.

The isolation rooms at the hospital were designed using a volumetric offset pressure control strategy for stable and straightforward room pressure control in each space. Utilizing Price Critical Controls low-pressure venture valves with tracking controllers and integrated packless silencers, the facility was able to maintain whisper-quiet and consistent airflow offset to each isolation room while also providing reheat control without the need for a secondary controller.

The Native BACnet TC facilitated simple, “gateway free” integration with the building management system for convenient monitoring, adjustment and trending of room conditions and settings. To ensure conformance with ASHRAE 170, each isolation room included a Native BACnet Room Pressure Monitor with LCD display and room status LED sidebars for easy visual verification of room pressure controls.  Onsite startup and commissioning for all room pressure monitors and controllers was performed by Price factory technicians.
