METHODS AND SYSTEMS FOR CONTROLLING DELIVERY OF FIRE SUPRESSANT
Methods and operations for controlling effective delivery of fire suppressant are disclosed. The fire suppression system comprises a control valve operatively coupled with a cylinder containing a fire suppressant. The system comprises a controller operatively coupled with the control valve. The controller is configured to command the control valve to open, discharging a flow of the fire suppressant at a first flow rate; and adjust the flow of the fire suppressant to a second flow rate during the discharge.
1 . A fire suppression system comprising:
a control valve operatively coupled with a cylinder containing a fire suppressant; and
a controller operatively coupled with the control valve, wherein the controller is configured to:
command the control valve to open, discharging a flow of the fire suppressant at a first flow rate; and
adjust the flow of the fire suppressant to a second flow rate during the discharge.
2 . The fire suppression system of claim 1 , wherein the second flow rate is lower than the first flow rate.
3 . The fire suppression system of claim 1 , further comprising:
one or more sensors configured to generate output signals conveying information related to fire conditions; and wherein
the controller is configured to:
determine one or more control parameters based on the output signals; and
adjust the first flow rate based on the one or more control parameters.
4 . The fire suppression system of claim 3 , wherein the controller is configured to
adjust the first flow rate based on one or more of the control parameters reaching a parameter threshold.
5 . The fire suppression system of claim 1 , wherein the controller is configured to:
adjust the second flow rate to a subsequent flow rate.
6 . The fire suppression system of claim 5 , wherein the subsequent flow rate is lower than the second flow rate.
7 . The fire suppression system of claim 5 , wherein the subsequent flow rate is higher than the second flow rate.
8 . The fire suppression system of claim 1 , wherein the second flow rate is different than a flow rate resulting from a decay in pressure in the fire suppressant source.
9 . A method for controlling delivery of fire suppressant, the fire suppression system comprising a control valve, a fire suppressant source, and a controller, the method comprising:
discharging a flow of the fire suppressant at a first flow rate; and
adjusting the flow of the fire suppressant to a second flow rate during the discharge.
10 . The method of claim 9 , wherein the second flow rate is lower than the first flow rate.
11 . The method of claim 9 , further comprising:
determining one or more control parameters based on the output signals from one or more sensors; and
adjusting the first flow rate based on the one or more control parameters.
12 . The method of claim 11 , wherein the first flow rate is adjusted based on one or more of the control parameters reaching a parameter threshold.
13 . The method of claim 9 , further comprising:
adjusting the second flow rate to a subsequent flow rate.
14 . A fire suppression system comprising:
a control valve operatively coupled with a cylinder containing a fire suppressant; and
a controller operatively coupled with the control valve, wherein the controller is configured to:
command the control valve to open and close, discharging the fire suppressant intermittently, the control valve being commanded to:
discharge a flow of the fire suppressant at a first flow rate;
stop the discharge; and
discharge a second flow of the fire suppressant at a second flow rate.
15 . The fire suppression system of claim 14 , wherein the control valve is commanded to:
discharge the fire suppressant at the first flow rate for a first discharge period of time; and
stop the discharge for a first shut-off period of time.
16 . The fire suppression system of claim 14 , wherein:
the controller is configured to determine the first discharge and/or the first shut off period of time.
17 . The fire suppression system of claim 14 , wherein:
the control valve is configured to stop the discharge after a second discharge period of the second flow.
18 . The fire suppression system of claim 15 , further comprising:
one or more sensors configured to generate output signals conveying information related to fire conditions; and
the controller is configured to:
determine one or more control parameters based on the output signals; and
determine the first discharge and/or the first shut off period of time based on the control parameters.
19 . The fire suppression system of claim 18 , wherein the controller is configured to:
determine the first flow rate based on the determined control parameters.
20 . The fire suppression system of claim 18 , wherein:
the controller is configured to determine the second flow rate based on the determined control parameters reaching a parameter threshold.
