What is function of decoupler line?

A decoupler line is used in various engineering and technical contexts to separate different sections of a system, allowing them to operate independently without interference. In control systems, it helps to isolate disturbances, ensuring that changes in one part do not adversely affect another. This enhances the overall stability and performance of the system by minimizing cross-coupling effects. In systems like HVAC, decouplers can also improve efficiency by allowing for independent control of different zones.
