What is the function of an inhibitor added to brine?

The addition of an inhibitor to brine serves the primary function of preventing corrosion and scale build-up. Inhibitors are chemicals specifically formulated to protect the metal components of refrigeration systems by forming a protective layer on metal surfaces, which reduces the reaction between the metal and the brine solution. This is particularly important in brine systems, as the interaction of salty brine can lead to corrosion of pipes, pumps, and other critical components, potentially leading to system failures and increased maintenance costs.

Moreover, scale build-up can result from mineral deposits that crystallize within the system, leading to blockages and reduced efficiency. By using inhibitors, the integrity and operational efficiency of the refrigeration system can be maintained over a longer period, thereby enhancing reliability and minimizing the need for repairs.

While there may be other benefits related to the stability of brine solutions or aspects of efficiency, the most crucial and direct function of inhibitors in this context clearly lies in their role in safeguarding the system's materials from damage due to corrosion and scale accumulation.
