The valve is a fast responding, pressure-independent device with a proven history of reliable performance. More detailed information on applying the valve in patient isolation rooms is provided. 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. Temperature is controlled by a local room thermostat which modulates a reheat coil valve. 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.
