What is the main function of the concentrator in a lithium bromide refrigeration system?

The main function of the concentrator in a lithium bromide refrigeration system is to increase the absorbency potential of the used absorbent. In this context, lithium bromide serves as the absorbent, which removes water vapor from the refrigerant. After absorption occurs, the solution becomes diluted, and concentrating this solution helps to restore its efficiency.

By increasing the absorbency potential, the concentrator ensures that the lithium bromide solution can effectively attract and remove more water vapor in subsequent cycles. This is critical for maintaining the refrigeration cycle's efficacy, optimizing the system's overall performance, and ensuring energy efficiency. A well-concentrated absorbent also aids in enhancing the system's cooling capacity, making the concentrator a vital component in sustaining the desired function of the refrigeration cycle.
