In this application, several isolation rooms and the corridor comprise an isolation wing. The corridor is supplied and exhausted with a constant flow of air to meet the ventilation, pressurization, and thermal requirements. The corridor's pressurization is maintained be a switched volumetric offset created between its supply and exhaust air flow rates. The corridor exhaust flow inversely tracks the total room offset of all isolation rooms to maintain proper pressurization in the isolation wing. As a result, negatively pressurized isolation rooms are provided with sufficient offset from a positively pressurized corridor and visa versa.
Temperature is controlled by a local thermostat which modulates a reheat coil valve.
Phoenix Controls airflow controls systems have long been relied upon for fume hood containment and room pressurization in chemistry laboratories. The same precise control and repeatability also makes the system ideal for cleanroom facilities. All material on this site is subject to change without notice.
