In an absorption system, what is the primary function of the absorber?

In an absorption system, the primary function of the absorber is to absorb heat. This process is essential for the operation of the system, which utilizes a refrigerant that absorbs heat from the environment.

In the absorber, a refrigerant vapor is brought into contact with a desiccant or absorption fluid, which has a strong affinity for the refrigerant. As the vapor enters the absorber, it is absorbed by the absorption fluid, causing the fluid to increase in temperature. This step is critical as it facilitates the transfer of heat from the surrounding environment into the refrigerant, creating a cooling effect.

The process of heat absorption enables the cycle to continue, allowing the system to extract heat from the source (like indoor air or water) and ultimately transfer it away where it can be released. Thus, the function of absorbing heat makes the absorber a key component in the overall efficiency and effectiveness of an absorption refrigeration system.
