What is the purpose of the pump in the absorber of the lithium bromide refrigeration system?

In a lithium bromide refrigeration system, the purpose of the pump in the absorber is primarily to facilitate and enhance the absorption process of water vapor into the lithium bromide solution. The lithium bromide acts as the absorbent, and when water vapor enters the absorber, the presence of the pump ensures that there is efficient mixing and contact between the vapor and the absorbent. This process maximizes the surface area for absorption, leading to a quicker and more effective removal of water vapor from the system.

By speeding up the absorption of water vapor, the pump helps maintain the effectiveness of the refrigeration cycle by ensuring that the system operates efficiently and at the desired performance levels. This results in a more stable and effective refrigeration process.
