System and method for injecting a fluid additive into a fluid dispensation system
First Claim
1. A method for operating a fluid additive control system to inject a fluid additive into a fluid dispensation system comprising:
- receiving a first control signal indicating that a fluid dispensation device within the fluid dispensation system is active;
determining a fluid additive quantity based upon the identity of the fluid dispensation device;
instructing a fluid additive injection system to inject the fluid additive into the fluid dispensation system in response to the activation and to maintain backpressure on the fluid additive to sustain a steady injection flowrate and prevent backflow;
receiving a second control signal from the fluid additive injection system when the fluid additive quantity for the fluid dispensation device has been injected into the fluid dispensation system; and
deactivating the fluid additive injection in response to the second control signal,wherein instructing the fluid additive injection system comprises activating a valve coupled to a pressurized fluid;
wherein activating the valve comprises receiving pressurized fluid from a pressurized fluid supply and transmitting the pressurized fluid into a piston cylinder coupled with a piston; and
wherein the pressurized fluid moves the piston from an initial position, injecting fluid additive into the fluid dispensation system in response to the pressurized fluid entering the piston cylinder.

Abstract
A method for operating a fluid additive control system to inject a fluid additive into a fluid dispensation system is provided. The method includes receiving a first control signal indicating that a fluid dispensation device within the fluid dispensation system is active, and determining a fluid additive quantity based upon the identity of the fluid dispensation device. The method also includes activating a fluid additive injection system, where the fluid additive dispensation system injects the fluid additive into the fluid dispensation system in response to the activation. The method further includes receiving a second control signal from the fluid additive injection system when the fluid additive quantity for the zone has been injected into the fluid dispensation system, and deactivating the fluid additive dispensation system in response to the second control signal.

5. A fluid additive system for injecting a fluid additive into a fluid dispensation system comprising:
-
a communication interface configured to receive and transmit control signals; a processing system coupled to the communication interface, and configured to; receive a first control signal through the communication interface indicating that a fluid dispensation device within the fluid dispensation system is active; determine a fluid additive quantity based on the identity of the fluid dispensation device; transmit a second control signal to a fluid additive injection system through a communication interface, wherein the second control signal activates the fluid additive injection system, and the fluid additive injection system injects the fluid additive into the fluid dispensation system in response to the activation; maintain backpressure on the fluid additive to sustain a steady injection flowrate and prevent backflow in response to the activation; receive a third control signal from the fluid additive injection system through the communication interface when the fluid additive quantity for the fluid dispensation device has been injected into the fluid dispensation system; transmit a fourth control signal to the fluid additive injection system through the communication interface in response to the second control signal, wherein the fourth control signal deactivates the fluid additive injection system; and receive a fifth control signal, and determine the fluid additive quantity based on the identity of the fluid dispensation device and the fifth control signal. - View Dependent Claims (6)
