For other applications, please contact your local Phoenix Controls representative . The isolation room is supplied and exhausted with a constant flow of air to meet the ventilation, pressurization, and thermal requirements. The room's pressurization is maintained by a fixed volumetric offset between the supply and exhaust air flow rates. Temperature is controlled by a local room thermostat which modulates a reheat coil valve. Each room's pressurization is maintained by a fixed volumetric offset between its exhaust and supply air flow rates.

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.
