Where is the weak liquor found in an ammonia absorber?

The weak liquor is found in the absorber of an ammonia absorption refrigeration system. In this context, the absorber plays a crucial role in the ammonia absorption process, where the ammonia vapor from the evaporator is absorbed into the weak liquor, typically a water-ammonia solution.

As the vapor enters the absorber, it comes into contact with the weak liquor, allowing ammonia to dissolve in the liquid. This process enriches the liquor with ammonia, increasing its concentration and transforming it into a stronger solution. The design of the absorber facilitates this exchange effectively, as it maximizes the contact between the vapor and the liquid, ensuring efficient absorption of ammonia.

In contrast, the other components mentioned — the condenser, evaporator, and generator — each have distinct functions in the refrigeration cycle and do not serve as locations for the weak liquor. The condenser is responsible for condensing the ammonia vapor into a liquid, the evaporator transforms the liquid ammonia into vapor for cooling purposes, and the generator creates a concentrated ammonia solution by heating the strong liquor. Thus, the absorber is the only part of the system where the weak liquor is specifically present and actively involved in the absorption process.
