Lithium Bromide chillers, also known as Lithium Bromide absorption chillers, use a solution of lithium bromide as the absorbent and water as the refrigerant. The cooling is achieved by utilizing the heat absorption of water vaporization in a high vacuum. In the lithium bromide chiller, the refrigerant water vapor, after evaporation, is absorbed by the lithium bromide solution, causing the solution to become diluted. This process occurs in the absorber, and then, using heat energy, the solution is heated to separate out the water, making the solution more concentrated. The steam obtained in the generator condenses into water in the condenser, is throttled, and then sent back to the evaporator for evaporation. This cycle continues to achieve continuous refrigeration.
