Abstract
A control is provided for a facility which has at least one pressurized room which control facilitates the making of selected changes in offset between the room and a space external thereto while maintaining a desired air flow balance. This is accomplished at least in part by making changes in the air flow for the external space in connection with such offset changes.
Claims18
A control for maintaining a desired air flow balance between at least one pressurized room and an external space connected to such room, there normally being a selected air flow offset between each room and the external space, the control comprising:
- an element which generates a signal indicative of a selected offset changing condition for at least one of said air flow offsets;
- and
- an air flow control for said external space which control is responsive to said signal for changing the air flow in at least said external space to achieve the selected changed offset while maintaining said desired air flow balance.
